                              June 30, 1998                                    
    
                                                       
                                                       
Note 1. Condensed Consolidated Financial Statements (Unaudited)                
---------------------------------------------------------------          
  The accompanying interim financial statements 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, 1997. The
information contained in this report is unaudited and subject to year-end
audit and adjustment. In the opinion of management, all adjustments (which
include only normal recurring adjustments) have been made which are necessary
for a fair presentation of the Company's consolidated financial position at
June 30, 1998 and 1997 and the consolidated statements of income and cash
flows for the six-month periods then ended. The results of operations for the
six months ended June 30, 1998 are not necessarily indicative of the results
of operations to be expected for the year ending December 31, 1998.

Note 2. Inventories
-------------------
  Substantially all of the Company's domestic fastener inventories are
priced on the lower of last-in, first-out (LIFO) cost or market method. 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:                                    
                                  (Unaudited)

                                    ----------              ---------
            TOTAL                  $29,871,999            $26,678,203
                                    ==========             ==========
                                                       
If the FIFO method of inventory valuation had been used by the Company for
all inventories, inventories would have been $8,904,119 and $8,704,119 higher
than reported at June 30, 1998 and December 31, 1997, respectively, and net
income would have been $128,000 and $140,000 higher than reported for the
six months ended June 30, 1998 and 1997, respectively. Included in other 
assets is long-term tooling inventory totaling $3,291,000 and $3,172,000 at
June 30, 1998 and December 31, 1997, respectively.

                 
Note 3. Comprehensive Income
----------------------------
  As of January 1, 1998 the Company adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income". Statement No.
130 establishes new rules for the reporting and display of comprehensive
income and its components; however, the adoption of this statement had no 
impact on the Company's net income or stockholders' equity. Statement No. 
130 requires unrealized gains or losses on the Company's available-for-sale
securities and foreign currency translation adjustments, which prior to 
adoption were reported separately in stockholders' equity, to be included in
comprehensive income. Prior year financial statements have been reclassified 
to conform to the requirements of Statement No. 130.
  During the six months ended June 30, 1998 and 1997, total comprehensive
income amounted to $8,654,655 and $6,271,122, respectively.

Note 4. Accounting Changes
--------------------------
  In June 1998, the Financial Accounting Standards Board issued Statement
No. 133, "Accounting for Derivative Instruments and Hedging Activities", 
which is required to be adopted in years beginning after June 15, 1999. The
Statement will require the Company to recognize all derivatives on the balance
sheet at fair value. Derivatives that are not hedges must be adjusted to fair
value through income. If the derivative is a hedge, depending on the nature
of the hedge, changes in fair value of derivatives will either be offset
against the change in fair value of the hedged assets, liabilities, or firm
commitments through earnings or recognized in other comprehensive income until
the hedged item is recognized in earnings. The ineffective portion of a 
derivative's change in fair value will be immediately recognized in earnings. 
The Company has not yet determined what the effect of Statement No. 133 will
be on the earnings and financial position of the Company.

Note 5. Reclassifications
-------------------------
  Certain reclassifications have been made to prior year amounts and balances
to conform with the 1998 presentation. 

Note 6. Use of Estimates
------------------------
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and 
assumptions that 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.

Quarter Ended June 30, 1998 vs. Quarter Ended June 30, 1997
-----------------------------------------------------------
   Consolidated net sales for the quarter ended June 30, 1998 were $45.0
million, versus $42.0 million for the quarter ended June 30, 1997, a 7.1%
increase. Net sales to customers outside the United States for the quarter
ended June 30, 1998 were $12.8 million, versus $11.2 million for the quarter
ended June 30, 1997, a 14.3% increase. Net sales for the fastener operation
for the quarter ended June 30, 1998 were $36.6 million, versus $34.1 million
for the quarter ended June 30, 1997, a 7.3% increase. Motor sales were $8.4
million for the quarter ended June 30, 1998, versus $7.8 million recorded for
the quarter ended June 30, 1997, a 7.7% increase. 
   The number of fastener units sold to independent customers increased
approximately 8.2% in the second quarter of 1998 compared to the second
quarter of 1997. The number of fastener units sold within North America
increased approximately 6.7% in the second quarter of 1998 compared to the
second quarter of 1997, and represented approximately 69.9% of total fasteners
sold in the second quarter of 1998. The number of fastener units sold into
Europe increased approximately 19.4% in the second quarter of 1998 compared
to the second quarter of 1997 and represented approximately 25.5% of total
fasteners sold in the second quarter of 1998. The increase in the European
market is a direct result of the strong European economy. The number of
fastener units sold into the Asia-Pacific region decreased approximately
17.4% in the second quarter of 1998 compared to the second quarter of 1997,
mainly as a result of the continued economic uncertainty in the region. The 
number of motors sold increased 9.3% in the second quarter of 1998 compared
to the second quarter of 1997.
  The average selling price for fasteners shipped in the second quarter of 
1998 decreased approximately 1.5% from $63.79 per thousand fasteners sold in
the second quarter of 1997 to $62.86 per thousand fasteners sold in the second
quarter of 1998. This decrease is mainly due to a change in product mix due to 
a return to more normal distributor ordering patterns. The average selling
price of Pittman motors decreased approximately 2.3% from the second quarter
of 1997 to the second quarter of 1998 due to a shift towards lower priced
brush motors from the higher priced brushless motors.
  Consolidated gross profit for the second quarter of 1998 was $13.9 million,
versus $13.0 million for the second quarter of 1997, an 6.9% increase. 
Fastener gross profit increased 8.8% in the second quarter of 1998 compared to
the second quarter of 1997 while motor gross profit remained about the same.
   Consolidated selling, general, and administrative expenses ("SG&A") for
the second quarter of 1998 were $8.1 million, versus $7.5 million for the
second quarter of 1997, a 8.0% increase. This increase was mainly caused by 
increased advertising expenses as well as increased technology related
expenses. SG&A , as a percent of sales, remained the same (17.9%) for both the
second quarter 1998 and the second quarter 1997. 
   Consolidated net income for the second quarter of 1998 was $3.9 million,
versus $3.6 million for the second quarter of 1997. Other income was 
negatively impacted in the second quarter of 1998 by realized currency losses
in the Asia-Pacific region.

Six Months Ended June 30, 1998 vs.Six Months Ended June 30, 1997
----------------------------------------------------------------
   Consolidated net sales for the six months ended June 30, 1998 were $91.7
million, versus $81.0 million for the six months ended June 30, 1997, a 13.2% 
increase. Net sales to customers outside the United States for the six months
ended June 30, 1998 were $25.9 million, versus $22.0 million for the six
months ended June 30, 1997, a 17.7% increase. Net sales for the fastener
operation for the six months ended June 30, 1998 were $74.5 million, versus
$66.2 million for the six months ended June 30, 1997, a 12.5% increase. Motor
sales were $17.2 million for the six months ended June 30, 1998, versus
$14.8 million for the six months ended June 30, 1997, a 16.2% increase.
   The number of fastener units sold to independent customers increased
approximately 17.3% in the first six months of 1998 compared to the first six
months of 1997. The number of fastener units sold within North America
increased approximately 17.0% in the first six months of 1998 compared to the
first six months of 1997, and represented approximately 70.4% of total
fasteners shipped in the first six months of 1998. Distributor shipments to
end customers continued strong in the first half of 1998, especially in the
personal computer market. Shipments in the first half of 1997 were still
affected by unusually high distributor inventory levels that have since
stabilized. The number of fastener units sold into Europe increased
approximately 26.0% in the first six months of 1998 compared to the first six
months of 1997 and represented approximately 25.3% of total fasteners sold in
the first six months of 1998. This increase is mainly due to the strong
European economy especially in the automotive sector. The number of fastener
units sold into the Asia-Pacific region decreased approximately 13.7% from
the first six months of 1997 compared to the first six months of 1998 as the
economic turmoil continues in this region. The number of motors sold increased
17.5% in the first six months of 1998 compared to the first six months of 1997
as demand from the semiconductor equipment manufacturing market and the data
storage and retrieval market which strengthened during the latter half of 1997
continued into 1998.
   The average selling price of fasteners shipped in the first six months of
1998 decreased approximately 2.7% from $64.51 per thousand fasteners sold in
the first six months of 1997 to $62.76 per thousand fasteners sold in the 
first six months of 1998. This decrease is mainly due to a change in product
mix toward lower margin fasteners as inventory levels at distributors are once
again replenished. The average selling price of Pittman motors decreased
slightly from $42.59 per motor in the first six months of 1997 to $42.27 per
motor in the first six months of 1998.
   Consolidated gross profit for the first six months of 1998 was $28.5
million, versus $24.7 million for the first six months of 1997, a 15.4%
increase. Fastener gross profit increased 15.6% in the first six months of 
1998 compared to the first six months of 1997 as a result of increased sales
and productivity improvements. Motor gross profit increased 13.7% in the first
six months of 1998 compared to the first six months of 1997. 
   Consolidated selling, general, and administrative expenses ("SG&A") for
the first six months of 1998 were $16.3 million, versus $14.8 million for the
first six months of 1997, a 10.1% increase. This increase was mainly caused by
increased commission expense due to continued strong end customer demand. As
a percent of sales, however, SG&A decreased from 18.3% in the first six months
of 1997 to 17.7% in the first six months of 1998. 
   Consolidated net income for the first six months of 1998 was $8.1 million,
versus $6.5 million for the first six months of 1997. Other income increased 
mainly due to higher investment income as a result of the increased amount of
short-term investments.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
                          RESULTS OF OPERATIONS
                         AND FINANCIAL CONDITION



Liquidity and Capital Resources
-------------------------------
   Net cash provided by operations totaled $10.9 million for the six months
ended June 30, 1998. These funds are being temporarily invested in
anticipation of increased capital spending and working capital needs during
the remaining half of 1998. Short-term investments increased 42.3% from $10.8
million at December 31, 1997 to $15.4 million at June 30, 1998. Accordingly,
the Company anticipates that its existing capital resources and cash flow
generated from future operations will enable it to maintain its current level
of operations and its planned growth for the foreseeable future.

Year 2000 Issues
----------------
   Many companies are currently in the process of determining what corrective
measures, if any, need to be taken in order to ensure that their computer
systems will not be disrupted by the Year 2000 ("Y2K") problem. The Y2K
problem relates to many of the computer systems in use today that have codes 
programmed to read dates as two digits. If the fields containing the two 
digits are not corrected, these programs will not function properly beginning
January 1, 2000 and could result in the creation of erroneous information or 
computer failures. 
   The Company is well underway towards having all critical systems Y2K
compliant by the close of 1998. The scope of the Company's effort includes
(1) information technology ("IT") such as software and hardware; (2) non-IT
systems or embedded technology such as microcontrollers contained in various
manufacturing and lab equipment, environmental and safety systems, and
facilities and utilities; and (3) readiness of key third parties, including 
suppliers and customers. In connection with its Y2K program, the Company's 
mainframe computer system has been updated so that it can be reasonably
assumed that system functions relating to operations, accounting, processing, 
order entry, inventory, production, shipping, and billing are Y2K compliant.
Other areas have been identified, including, a few overseas systems, where a
Y2K compliance program has been implemented, which it can be reasonably
assumed will be completed during 1998. The Company retained the services of an
independent company to review and catalogue its IT and non-IT systems to
determine the remaining task of complying with Y2K. Their efforts identified
357 items of which 311 items were classified as unknown while 46 were found to
be non-compliant. It is expected that all items will be cleared by December
31, 1998, except for internal E-mail and internal scheduler software. The 
latter is expected to be compliant by March, 1999. The cost of completing 
compliance will be $200,000 to $300,000 except for E-mail and scheduler. The
latter will cost approximately $200,000.
   The Company also seeks to address the Y2K activities of its suppliers, 
service providers, distributors, and other business relationships. The Company
is and will be in contact with key suppliers and customers to determine if 
they are Y2K compliant, and if not when they will be. This information will be
used to determine the extent of interruption that could occur in the Company's
operations. If third parties do not convert their systems in a timely manner
and in a way that is compatible with the Company's, the Y2K issue could have a
material adverse effect on the Company's operations. The Company believes that
its communications with its suppliers and customers will minimize these risks.

Forward-Looking Statements
--------------------------
   Forward-looking statements 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 the cost and
availability of the supply chain resources, and foreign economic conditions, 
including currency rate fluctuations.
