              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  June 30, 2004

Note 1.  Condensed Consolidated Financial Statements (Unaudited).

         The accompanying condensed consolidated financial statements and notes
should be read in conjunction with the annual financial statements and notes
thereto included in the Company's Annual Report for the year ended December 31,
2003. The information contained in this report is unaudited and, in the opinion
of management, reflects all adjustments (which include only normal recurring
adjustments) necessary for a fair presentation of the Company's condensed
consolidated financial position at June 30, 2004 and 2003 and the condensed
consolidated statements of income and cash flows for the six-month periods then
ended. The results of operations for the three and six months ended June 30,
2004 are not necessarily indicative of the results of operations to be expected
for the year ending December 31, 2004.

Note 2.  Inventories.

         Substantially all of the Company's domestic fastener inventories are
priced on the last-in, first-out (LIFO) method, at the lower of cost or market.
The remainder of the inventories are priced on the first-in, first-out (FIFO)
method, at the lower of cost or market. Inventories are as follows:

         (Dollars in thousands)

                      June 30, 2004   December 31, 2003
                      -------------   -----------------
Raw material             $ 2,749          $ 2,807
Tooling                    6,171            5,540
Work-in-process           11,755           11,541
Finished goods            24,762           28,624
                         -------          -------
TOTAL                    $45,437          $48,512
                         =======          =======

         If the FIFO method of inventory valuation had been used by the Company
for all inventories, inventories would have been $10,259,000 and $10,072,000
higher than reported at June 30, 2004 and December 31, 2003, respectively, and
net income would have been $127,000 and $230,000 higher than reported for the
six months ended June 30, 2004 and 2003, respectively. Long-term tooling
inventory totaling $1,290,000 at June 30, 2004 and $1,285,000 at December 31,
2003 is included in Other Assets.

Note 3.  Bank Debt.

                  As of June 30, 2004, the Company had five unsecured
line-of-credit facilities available, all of which bear interest at interest rate
options provided in the facilities and are reviewed annually by the banks for
renewal. The facilities are as follows:

                                       5
<PAGE>

         o        a working capital facility that permits maximum borrowings of
                  $7,000,000, due on demand, under which no amounts were
                  outstanding at June 30, 2004;

         o        general facility that allows for borrowings of up to
                  $12,000,000, under which no amounts were outstanding at June
                  30, 2004;

         o        a facility that allows for borrowings of up to $15,000,000,
                  under which a short-term loan of $1,823,000 was outstanding at
                  June 30, 2004 at an interest rate of 2.74%;

         o        a facility that permits borrowings of up to $30,000,000, under
                  which a short-term loan of $3,312,000 was outstanding at June
                  30, 2004 at an interests rate of 1.90%; and

         o        a committed line-of-credit that permits borrowings of up to
                  $8,000,000, under which no amounts were outstanding at June
                  30, 2004.

         These line of credit facilities require that the Company comply with
certain financial covenants. At June 30, 2004, the Company was in compliance
with all financial covenants under these faculties.

         In addition to the above domestic line-of-credit facilities, the
Company's subsidiary, M.A.E. S.p.A. (MAE), has two short-term credit facilities
under which $461,000 was outstanding at June 30, 2004. MAE also has an
outstanding mortgage on its building, of which $558,000 is classified as
short-term debt and $2,789,000 is classified as long-term debt at June 30, 2004.

Note 4.  Comprehensive Income.

         Total comprehensive income amounted to $5,501,000 and $2,912,000 for
the three months ended June 30, 2004 and 2003, respectively, and $11,543,000 and
$4,105,000 for the six months ended June 30, 2004 and 2003, respectively.

Note 5.  Accounting for Stock Options.

         The Company follows Accounting Principles Board Opinion No. 25 ("APB
25"), "Accounting for Stock Issued to Employees" and related interpretations in
accounting for stock options. Under APB 25, if the exercise price of stock
options granted equals or exceeds the market price of the underlying common
stock on the date of grant, no compensation expense is recognized. Statement of
Financial Accounting Standards No. 123 ("SFAS No. 123") requires pro forma
information regarding net income and earnings per share as if the Company had
accounted for its employee stock options under the fair value method of SFAS No.
123. The fair value of each option granted was estimated on the date of grant
using the Black-Scholes option-pricing model. For purposes of pro forma
disclosures, the estimated fair value of the options is amortized to expense
over the options' vesting period. Had compensation costs for the Company's plans


                                       6

been determined based on the fair value at the grant date for awards under these
plans consistently with the method of SFAS No. 123, the impact on the Company's
financial results would have been as follows:

Note 6.  Use of Estimates.

         The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that may affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

Note 7.  Components of Net Periodic Pension Cost.

         Net pension costs included the following components:

Item 2.  Management's Discussion and Analysis of Financial Condition and
         Results of Operations.

Quarter Ended June 30, 2004 vs.  Quarter Ended June 30, 2003

         Consolidated net sales for the quarter ended June 30, 2004 were $61.7
million, versus $47.4 million for the quarter ended June 30, 2003, a 30.2%
increase. Net sales to customers outside the United States for the quarter ended
June 30, 2004 were $25.4 million, versus $18.7 million for the quarter ended
June 30, 2003, a 35.8% increase. Net sales for the Fastening Technologies
segment for the quarter ended June 30, 2004 were $32.8 million, versus $24.9
million for the quarter ended June 30, 2003, a 31.7% increase. Net sales for the
Motion Technologies segment were $12.4 million for the quarter ended June 30,
2004, versus $11.3 million recorded for the quarter ended June 30, 2003, a 9.7%
increase. Net sales for the Distribution segment for the quarter ended June 30,
2004 were $16.5 million, versus $11.3 million for the quarter ended June 30,
2003, a 46.0% increase.

         Within the Fastening Technologies segment, sales volume increased 26.0%
in both the domestic and international markets from the second quarter of 2003
compared to the second quarter of 2004, while the average selling price
increased approximately 5.3% due to a change in product mix as well as a 2.0%
price increase that went into effect January 1, 2004. Within the Motion
Technologies segment, the number of motors sold under the Pittman brand
increased approximately 14.0% in the second quarter of 2004 compared to the
second quarter of 2003, while the average selling price per motor increased
approximately 9.3%, primarily due to a price increase effective January 1, 2004.
Motor sales from MAE were $2.5 million in the second quarter of 2004 compared to
$3.0 million in the second quarter of 2003. Within the Distribution segment,
sales into Europe increased approximately 48.8%, sales into North America
increased 19.9%, while sales into Asia increased approximately 86.4% from the
second quarter of 2003 to the second quarter of 2004. This segment continues to
experience international growth as personal computer and electronics companies
shift production to other global areas to take advantage of lower assembly
costs.

         Consolidated gross profit for the second quarter of 2004 was $20.6
million, versus $13.0 million for the second quarter of 2003, an increase of
58.5%. Gross profit as a percent of sales increased from 27.4% in the second
quarter of 2003 to 33.4% in the second quarter of 2004. The Company continues to
benefit from increased volume, especially in the manufacturing of fasteners
where increased plant and machinery utilization occurred without corresponding
increases in fixed costs.

         Consolidated selling, general, and administrative expenses ("SG&A") for
the second quarter of 2004 were $13.0 million, versus $11.6 million for the
second quarter of 2003, a 12.1% increase. This increase was caused mainly by
increased wages and benefits, including an approximate 13.4% increase in medical
costs and a 16.7% increase in pension costs.

                                       10
<PAGE>

         Consolidated net income for the second quarter of 2004 was $5.3
million, versus $1.3 million for the second quarter of 2003. The effective tax
rate increased from 21.6% in the second quarter of 2003 to 32.5% in the second
quarter of 2004 due to the fact that a greater proportion of income was produced
in the United States, with a higher corporate income tax rate compared to the
locations in which income was generated in the second quarter of 2003.

Six Months Ended June 30, 2004 vs.  Six Months Ended June 30, 2003

         Consolidated net sales for the six months ended June 30, 2004 were
$125.0 million, versus $92.3 million for the six months ended June 30, 2003, a
35.4% increase. Net sales to customers outside the United States for the six
months ended June 30, 2004 were $52.7 million, versus $35.9 million for the six
months ended June 30, 2003, an increase of 46.8%. Net sales for the Fastening
Technologies segment for the six months ended June 30, 2004 were $66.5 million,
versus $48.5 million for the six months ended June 30, 2003, a 37.1% increase.
Net sales for the Motion Technologies segment were $25.0 for the six months
ended June 30, 2004, versus $21.2 million for the six months ended June 30,
2003, a 17.9% increase. Net sales for the Distribution segment for the six
months ended June 30, 2004 were $33.6 million, versus $22.6 million for the six
months ended June 30, 2003, a 48.7% increase.

         Within the Fastening Technologies segment, sales volume increased 28.9%
from the first six months of 2003 compared to the first six months of 2004,
while the average selling price increased 7.0%. This segment continues to
benefit from the improved economy, especially in the gaming, security, and
medical markets as well as the segment's traditional telecommunications and
datacommunications markets. In addition, a 2.0% price increase went into effect
on January 1, 2004 as well as an additional 2.0% surcharge in May, 2004 to cover
additional raw material cost increases. Within the Motion Technologies segment,
the number of motors sold under the Pittman brand increased approximately 17.5%
in the first six months of 2004 compared to the first six months of 2003, while
the average selling price increased approximately 7.2%. Within the Distribution
segment, the Company experienced strong international growth during the first
six months of 2004 compared to the same period in 2003 as the Asian market
increased 92.0% and the European market increased 42.8%. The domestic market
continues to strengthen also as sales increased 25.8% in North America.

         Consolidated gross profit for the first six months of 2004 was $43.1
million, versus $25.6 million for the first six months of 2003, a 68.4%
increase. Increased volume led to the improvement in gross margin in all
segments as increased costs for wages and benefits were offset by productivity
improvements and better utilization of capacity.

         Consolidated SG&A expenses for the first six months of 2004 were $26.8
million, or 21.4% of sales, versus $23.1 million, or 25.0% of sales, for the
first six months of 2003, an increase of 16.0%. In addition to increased wages
and employee benefits, legal and professional fees increased approximately 80%
from 2003 to 2004 due mainly to increased audit and Sarbanes-Oxley related
expenses.

                                       11
<PAGE>

         Consolidated net income for the first six months of 2004 was $11.2
million, versus $1.9 million for the first six months of 2003. Interest expense
decreased from $524,000 in the first six months of 2003 to $167,000 in the first
six months of 2004 due to less debt outstanding. The effective tax rate
increased from 27.1% in the first six months of 2003 to 32.0% in the first six
months of 2004 due to the fact that a greater proportion of income was produced
in the United States, with a higher corporate income tax rate compared to the
locations where income was generated in the first six months of 2003.

Liquidity and Capital Resources

         Cash and cash equivalents at June 30, 2004 were $22.4 million compared
to $8.4 million at December 31, 2003. Working capital totaled $85.8 million at
June 30, 2004 compared to $69.5 million at December 31, 2003.

         Net cash of $17.7 million was provided by operating activities for the
six months ended June 30, 2004 compared to $12.5 million provided by operating
activities for the six months ended June 30, 2003. The Company continued to
generate cash from further reductions in overall inventory levels during the
first half of 2004. However, as sales volume increased, the level of accounts
receivable also increased, particularly in the European region where payment
terms are generally longer than domestic payment terms.

         Net cash used in investing activities totaled $1.2 million for the six
months ended June 30, 2004. The Company continues to exercise caution with its
capital expenditures as it attempts to utilize current capacity during the
economic recovery.

         Net cash used in financing activities totaled $3.7 million for the six
months ended June 30, 2004 compared to $14.6 million for the six months ended
June 30, 2003. Because of the decreased capital expenditures, the Company repaid
short-term debt during both years.

         The Company's principal contractual obligations are the repayment of
its short-term debt (see Note 3) and the payment of operating lease commitments
covering certain automobiles, office space, and office equipment that are listed
in Note 12 to the Company's Annual Report for the year ended December 31, 2003.
The Company anticipates that its existing capital resources and cash flow
generated from future operations as well as existing short-term lines of credit
will enable it to maintain its current level of operations and its planned
growth for the foreseeable future.

Critical Accounting Policies

         The Company has identified a number of its accounting polices that it
has determined to be critical. These critical accounting policies primarily
relate to financial statement assertions that are based on the estimates and
assumptions of management, and the effect of changing those estimates and


                                       12
<PAGE>

assumptions could have a material effect on the Company's financial statements.
The following is a summary of those critical accounting policies.

Inventories

         The Company's domestic fastener inventories are priced on the last-in,
first-out (LIFO) method of accounting. Other inventories, representing
approximately 78% and 79% of total inventories at June 30, 2004 and December 31,
2003, respectively, are priced on the first-in, first-out (FIFO) method.
Reserves are recorded for obsolete, excess, and slow-moving inventories based on
management's estimates about future demand and market conditions. At June 30,
2004, the Company's inventory balance of $45,437,000 was net of a reserve for
obsolete, excess, and slow-moving inventories of approximately $3,532,000. At
December 31, 2003, the Company's inventory balance of $48,512,000 was net of a
reserve for obsolete, excess, and slow-moving inventories of approximately
$3,512,000. If the estimated reserves for obsolete, excess, and slow-moving
inventories are not sufficient based on actual future demand, additions to the
reserve may be required.

Accounts Receivable

         The Company maintains an allowance for doubtful accounts for trade
receivables for which collectability is uncertain. At June 30, 2004 and December
31, 2003, this allowance was approximately $1,014,000 and $886,000,
respectively. In estimating uncollectible accounts, the Company considers
factors such as current overall economic conditions, industry-specific economic
conditions, and historical and anticipated customer performance. While the
Company believes that its procedures effectively address exposure for doubtful
accounts, changes in the economy, industry, or specific customer conditions may
require adjustments to the allowance.

Goodwill

         SFAS No. 142 requires that goodwill no longer be amortized, and
instead, be tested for impairment on a periodic basis. At June 30, 2004, the
Company had $41,111,000 in goodwill. The process of evaluating the potential
impairment of goodwill is highly subjective and requires significant judgments
at many points during the analysis. In estimating the fair value of the
reporting units with recognized goodwill for the purposes of the Company's 2003
financial statements, the Company made estimates and judgments about the future
cash flows of these reporting units. The Company's cash flow forecasts were
based on assumptions that are consistent with the plans and estimates the
Company is using to manage the underlying businesses. In addition, the Company
made certain judgments about allocating shared assets to the balance sheet for
those reporting units. Based on its estimates, the Company has concluded that
there is no impairment of its goodwill as of December 31, 2003. However, changes
in these estimates could cause one or more of the reporting units to be valued


                                       13
<PAGE>

differently in the future. The Company will evaluate its goodwill again for
impairment as of October 1, 2004, or sooner if deemed necessary by management.

Pensions

         Accounting for the Company's defined benefit plan requires that amounts
recognized in the financial statements be determined on an actuarial basis. The
most significant elements in determining the Company's pension expense are
pension liability discount rates and the expected return on plan assets. The
pension discount rate reflects the current interest rate at which pension
liabilities could be settled at the end of the year. At the end of each year,
the Company determines the discount rate to be used to discount plan
liabilities. In estimating this rate, the Company looks to rates of return on
high-quality, fixed-income investments. At December 31, 2003, the Company
determined this rate to be 6.25% and no adjustment to this rate has been made
for the six months ended June 30, 2004. Historically, the Company has assumed
that the expected long-term rate of return on plan assets will be 8.00%, and
this expected rate of return has been used for many years. Because the Company's
pension plan assets have earned substantially less than 8.00% in the last two
years, the Company reduced the expected long-term rate of return to 7.00% in
2003 and no adjustment has been made for the six months ended June 30, 2004.
Should the downward trend in return on pension assets continue, future pension
expense would likely increase. The net effect of changes in the discount rate,
as well as the effect of differences between the expected return and the actual
return on plan assets, have been deferred in accordance with SFAS No. 132 and
will ultimately affect future pension expense.

Derivative Instruments and Hedging

         The Company manages risks associated with foreign exchange rates and
interest rates with derivative instruments. The Company does not use derivative
instruments for trading or speculative purposes, and only uses derivatives when
there is an underlying exposure. The evaluation of hedge effectiveness is
subject to assumptions based on the terms and the timing of the underlying
exposures. All derivative instruments are recognized in the Consolidated Balance
Sheet at fair value, which is generally based on quoted market prices.

Forward-Looking Statements

         Forward-looking statements, within the meaning of Section 27A of the
Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934
under the Private Securities Litigation Reform Act of 1995, are made throughout
this Management's Discussion and Analysis. The Company's results may differ
materially from those in the forward-looking statements. Forward-looking
statements are based on management's current views and assumptions, and involve
risks and uncertainties that significantly affect expected results. For example,
operating results may be affected by external factors such as: changes in laws
and regulations, changes in accounting standards, fluctuations in demand in


                                       14

markets served by the Company, particularly the computer and telecommunications
markets, fluctuations in the cost and availability of the supply chain
resources, and foreign economic conditions, including currency rate
fluctuations.

         Reference is made to Part 2, Item 7A of the Company's Form 10-K Annual

Item 4.  Controls and Procedures.

         Evaluation of Disclosure Controls and Procedures

         As required by Rule 13a-15 under the Securities Exchange Act of 1934,
as of the end of the period covered by this report, the Company carried out an
evaluation, under the supervision and with the participation of the Company's
management, including the Chief Executive Officer and the Chief Financial
Officer, of the effectiveness of the design and operation of the Company's
disclosure controls and procedures. Based on this evaluation, the Company's
management, including the Chief Executive Officer and the Chief Financial
Officer, concluded that the Company's disclosure controls and procedures are
effective for recording, processing, summarizing, and reporting the information
the Company is required to disclose in the reports it files under the Securities
Exchange Act of 1934, within the time periods specified in the SEC's rules and
forms.

         Changes in Internal Control Over Financial Reporting

         There have been no significant changes in the Company's internal
controls over financial reporting (as such term is defined in Rules 13a-15 and
15d-15) during the three months and six months ended June 30, 2004 that have
materially affected, or are reasonably likely to materially affect, the
Company's internal control over financial reporting.
