                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)


1. In the opinion of the Company, the accompanying unaudited financial
statements contain all adjustments necessary to present fairly the financial
position of the Company as of June 30, 1999 and December 31, 1998 and the
results of operations and changes in cash flows for the indicated periods.

The Company uses estimated gross profit rates to determine the cost of goods
sold during interim periods. Actual results could differ from those estimates
and will be adjusted, as necessary, following the Company's annual physical
inventory in the fourth quarter.

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.

2. The results of operations for the three-month period ending June 30, 1999 are
not necessarily indicative of the results to be expected for the year.

3. The Company extends credit primarily on the basis of 30-day terms to various
companies doing business primarily in the automotive and appliance industries.
The Company has a concentration of credit risk primarily within the automotive
industry and in the Midwestern United States.

4. The Company is, from time to time involved in litigation, including
environmental claims, in the normal course of business. While it is not possible
at this time to establish the ultimate amount of liability with respect to
contingent liabilities, including those related to legal proceedings, management
is of the opinion that the aggregate amount of any such liabilities, for which
provision has not been made, will not have a material adverse effect on the
Company's financial position.

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

     Net sales and lease revenues for the second quarter of 1999 amounted to
$12,933,690, which represents an increase of 19.5% compared with the second
quarter of 1998. Revenues from the assembly equipment segment increased 11.6%,
compared with the second quarter of 1998, while revenues in the fastener segment
increased 22.2%. These increases are largely attributable to the continued
strength in the automobile industry, which is the Company's primary market. It
should be noted that during the second quarter of 1998, revenues were negatively
affected by a work stoppage experienced by one of the major automobile
manufacturers, which significantly limited revenues during that period.
Nevertheless, revenues have increased appreciably compared to the prior year.

     As previously announced, the Company's 1999 second quarter earnings were
adversely impacted by costs incurred in connection with a recall of vehicles
that contained certain non-conforming parts which were manufactured by the
Company. The Company has negotiated a settlement related to the recall and also
incurred certain internal costs related to repair of the affected vehicles. The
total costs incurred in connection with the recall, and the related settlement,
amounted to $944,000, before taxes ($623,000, after taxes.) Of the pre-tax
amount, approximately $910,000 was charged to cost of goods sold, and is the
primary factor contributing to the reduction in gross profits during the second
quarter of 1999. Gross margins, excluding this adjustment, were approximately
equal to those reported during the second quarter and first six months of 1998.
Shipping, selling and administrative expenses increased approximately $329,000
compared to the second quarter of 1998. The primary factors contributing to this
increase included $76,000 for consulting expenses related to data processing,
higher state tax expense of $64,000, higher freight and shipping expenses of
$50,000, $34,000 in expenses related to the product recall, increases in salary
expense of $30,000 and depreciation expense of $22,000.

     The Company's financial condition continues to be sound. During the
quarter, working capital decreased by approximately $0.2 million and totaled
$12.5 million at the end of the quarter. Accounts receivable balances were
essentially unchanged during the quarter, although the balance has increased
compared to the year-end 1998 balances, largely due to the increase in sales
during the most recent period compared with the fourth quarter of 1998. Capital
expenditures during the second quarter amounted to $520,000, including $81,000
related to computer system conversion costs. Other major expenditures included
$247,000 for cold-heading equipment, $76,000 for a lathe used in production of
tooling for assembly equipment, $60,000 for various test equipment utilized in
quality control and $38,000 for new telephone and voice mail systems at two
facilities.

     The Company continues to make scheduled quarterly principal payments of
$450,000 plus interest at a variable rate on its term note. At June 30, 1999,
the principal balance was $4.05 million and the interest rate was approximately
5.9%. The Company also has a $1.0 million line of credit from the Bank of
America. This line remains unused and is scheduled to expire on May 30, 2000.
The Company believes that its current cash, cash equivalents and existing
borrowings will be sufficient to provide adequate working capital through at
least the next twelve months.

     During the second quarter of 1999, the Company repurchased 1,000 shares of
its stock under the terms of its existing stock repurchase program, which
provides for the repurchase of an aggregate of 200,000 shares, with such
purchases to be made, from time to time, in the open market, or in private
transactions. The most recent purchases were made in the open market, at an
aggregate purchase price of $24,175, bringing the total purchases made under the
current program to 136,196 shares at an average price of $14.51 per share. It is
management's intention to continue this program, provided conditions are
favorable and funding for repurchases is available.

YEAR 2000 COMPLIANCE

     The Company continues to make ongoing assessments of its state of readiness
with respect to Year 2000 ("Y2K") issues. This process can logically be
segregated into two major categories -- information technology and
non-information technology. The first category encompasses issues related to
computer equipment and software used in the operation of the business, while the
second category deals with all other aspects of Y2K issues, including, but not
limited to, manufacturing equipment and systems, supplier and customer
preparedness and facility related issues such as telecommunications equipment,
HVAC systems and facility security.

     The Company has determined that its information technology systems are not
Y2K compliant and has further determined that its existing software will not
meet the needs of the organization in the future. Accordingly, significant
resources have been allocated to the process of implementing a new data
processing solution that will better meet the needs of the organization while
also addressing the Y2K issues. The implementation of this solution is planned
in three phases. The first two phases include hardware and network installation
and the installation of application software related to financial reporting,
inventory control, order processing, purchasing and payroll. Hardware and
network installation has been completed. The software testing and training has
been completed, and one facility has successfully completed implementation and
is now utilizing the new software. Other facilities, which were originally
scheduled to complete implementation during the second quarter, have delayed
implementation until September 1, 1999 due to unanticipated issues related to
data conversion. This delay has resulted in the necessity of delaying
implementation of the final phase, which consists of implementation of the
manufacturing software modules and, while this final phase is currently
underway, implementation is now scheduled to begin late in the fourth quarter.
Given the delays experienced to date, the Company is in the process of
identifying certain mission critical features of its existing data processing
systems that may need to be modified so that they are Y2K compliant in the event
that the final phase of the new software implementation is delayed beyond
December 31, 1999. Implementation of the new data processing systems is expected
to resolve the fundamental Y2K information technology issues, and we believe
that it will also have significant benefits to the organization in terms of more
efficient operations, improved access to information related to production
control and inventory management as well as improvements in customer service.
While it is not possible to segregate the costs of this project into segments
that are solely related to resolution of Y2K issues and costs associated with
the other aspects of the project, the overall investment in information
technology is expected to total approximately $1.3 million. Actual expenditures
related to this project, through the first half of 1999, totaled approximately
$955,000. This project encompasses the Company's solution to Y2K issues as well
as significant improvements in information systems. As such, nearly all of the
information technology budget is committed to this project. No other information
technology projects have been deferred because of resources committed to this
project. Funding for this project is expected to be available from internal
sources.

     While we believe that the timetable for implementation is realistic and
attainable, it is not possible to be absolutely certain of completion within the
scheduled time frame. The failure to correct a material Y2K issue could result
in an interruption in, or failure of, certain normal business activities or
operations. Such failures could materially and adversely affect the Company's
results of operations, liquidity and financial condition. However, manual
systems currently exist for the essential functions covered by this project, and
such manual systems could be utilized on a temporary basis if the project falls
substantially behind schedule, so the potential disruption resulting from a
delay in implementation is expected to be manageable.

     With respect to non-information technology issues, the Company has
completed an inventory of the production and support equipment and systems
currently in use and determined that most such equipment does not contain
microprocessors or embedded microchips and therefore will not be affected by Y2K
issues. Certain, more modern, production equipment contains microprocessors. For
the majority of that equipment, we have received the manufacturer's confirmation
that the equipment is Y2K compliant. In a limited number of cases, we are
awaiting responses from the equipment manufacturer and plan to continue efforts
to ascertain the status of that equipment with respect to Y2K issues. We believe
that we have alternative equipment available that could be utilized on an
interim basis should some of the modern equipment fail unexpectedly. This
eventuality would cause disruptions in our production schedules as the older
equipment is


                                       11


<PAGE>   13



less efficient than the newer equipment, and our manufacturing costs would be
adversely affected as well. At this time, we are unable to quantify the monetary
impact of this potential disruption.

     The Company has also requested that each of its major customers and
critical suppliers advise the Company of their current state of readiness, as
well as their plans to resolve any open Y2K issues. The response to these
requests has been varied. In general, most firms contacted have indicated that
their systems are Y2K compliant, or that Y2K issues will be resolved during
1999. Typically, larger firms are better prepared than smaller concerns. A
number of smaller customers have not, as yet, responded to our inquiries with
respect to Y2K compliance. Ongoing follow up contacts with those vendors and
customers that have not yet indicated Y2K compliance are being made in an effort
to determine that their compliance efforts are progressing. The Company will
continue to monitor the status of its key vendors and customers and will develop
appropriate contingency plans as more information becomes available.

     The Company's contingency plans related to these issues are not complete at
this time. Preliminary work in this area has focused upon information technology
issues and in-house manufacturing issues. While we continue to evaluate the
situation, based upon information currently available, we anticipate that we
will be able to maintain core operations with existing manual systems
supplemented by scheduling overtime to offset the reduced efficiency of manual
systems. Contingency planning with respect to third parties is limited by
incomplete information concerning their state of readiness, and we are unable,
at this time, to make a reasonable estimate of the impact Y2K issues will have
on our customers or suppliers. We are evaluating the desirability of purchasing
additional supplies of raw materials and critical operating supplies during the
second half of 1999. However, if our customers' plans include a similar
contingency, it is possible that we will use any such safety stock to satisfy
our customers' requests that we, in turn, supply them with safety stock. We are
also evaluating what action will be required to protect the Company's facilities
from the effects of cold weather in the event that utility service is disrupted.
To date, we have received notification of Y2K compliance from certain utility
companies, but others have yet to respond to our requests for information. Our
plans will be revised as more information becomes available.

     Overall, our outlook for the second half of the year is positive. Backlogs,
while somewhat lower than one year ago, are adequate for normal operations, and
demand for our products continues to be fairly strong. In general, the overall
economic outlook is for continued growth, and we expect that the Company will
continue to do well in the months ahead.

     THIS DISCUSSION CONTAINS CERTAIN "FORWARD-LOOKING STATEMENTS" WHICH ARE
INHERENTLY SUBJECT TO RISKS AND UNCERTAINTIES THAT MAY CAUSE ACTUAL EVENTS TO
DIFFER MATERIALLY FROM THOSE DISCUSSED HEREIN. FACTORS WHICH MAY CAUSE SUCH
DIFFERENCES IN EVENTS INCLUDE, AMONG OTHER THINGS, FLUCTUATIONS IN GENERAL
ECONOMIC CONDITIONS, CONSUMER DEMAND, THE GAIN OR LOSS OF A KEY CUSTOMER, THE
PRICE AND AVAILABILITY OF THE COMPANY'S PRIMARY RAW MATERIALS, OR Y2K ISSUES
THAT MAY AFFECT THE COMPANY, OR ITS KEY SUPPLIERS OR CUSTOMERS. THEREFORE,
READERS ARE CAUTIONED NOT TO PLACE UNDUE RELIANCE UPON SUCH FORWARD-LOOKING
STATEMENTS.
