                 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 September 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 September 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 during the third quarter of 1999 totaled
$11,721,458, which represents an increase of approximately 13.5% compared with
the third quarter of 1998. On a year to date basis, sales and lease revenues for
the first nine months of 1999 total $37,172,628 which is an increase of
approximately 13.2% over the first nine months of 1998. During 1999, revenues
from the sale of fasteners have increased approximately 16% when compared with
both the third quarter and the first nine months of 1998. Revenues within the
assembly equipment segment have also increased when compared to both the third
quarter and the first nine months of 1998, although the increase has been a more
modest 4%.
     Net income improved to $816,774, or $.71 per share on 1,152,139 average
shares outstanding during the third quarter of 1999, compared with $718,506, or
$.62 per share on 1,155,535 average shares outstanding during the third quarter
of 1998. The increase in net income, compared with the third quarter of 1998, is
primarily attributable to increased sales volume, offset, in part, by increases
in depreciation and certain administrative costs. During the third quarter of
1999, gross margins increased compared with the third quarter of 1998. Most of
this increase is attributable to the increased level of sales recorded during
the third quarter of 1999. Excluding the effect of an adjustment to certain
estimates recorded in the third quarter of 1998, the gross margin percentage in
1999 is approximately equal to that of the prior year. Selling and
administrative expenses for the quarter were approximately $250,000 higher in
1999 than during the third quarter of 1998. The major factors contributing to
the increase include higher consulting expenses related to data processing of
$110,000, higher freight and shipping expenses of $74,000, higher state tax
expense of $44,000, and a $31,000 increase in depreciation expense. These
increases were partially offset by reductions in travel and non-data processing
consulting.

     The Company's financial condition remains sound. Working capital
increased by approximately $0.4 million during the quarter and totaled $12.9
million at the end of the quarter. Capital expenditures during the quarter
amounted to $138,000, which was expended primarily for new equipment used in the
manufacture of fasteners.

     The Company continues to make scheduled quarterly principal payments of
$450,000 plus interest, at a variable rate, on its term note. At September 30,
1999, the principal balance of this note was $3.6 million and the interest rate
was approximately 6.4%. The Company also has a $1.0 million line of credit from
Bank of America. This line is currently 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 meet the Company's needs through the
next twelve months.

     During the third quarter of 1999, the Company purchased 1,600 shares of
its stock under the terms of its existing stock repurchase program. The program
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 $64,131, bringing the total purchases made under the
current program to 137,796 shares at an average price of $14.63 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




                                       10
<PAGE>   12
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.
     Previously, the Company determined that its information technology
systems were not Y2K compliant and further determined that its existing software
would 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 would better meet the needs of the organization
while also addressing the Y2K issues. At this time, one facility has completed
its conversion to new data processing systems. At all other facilities, hardware
and software are installed, and we are currently processing data on both our new
software and our older software in order to be certain that the new software is
functioning properly. This testing has been successfully underway for some time,
and we expect the changeover to the new software will be completed in early
November. The completion of this phase of our data processing initiative will
eliminate all critical Y2K deficiencies in our current information systems and
we believe that it will also provide 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. The final phase of this project encompasses enhancements to information
management with respect to manufacturing systems. The final phase, which was
originally scheduled for completion during 1999 has been delayed and is not
expected to be completed until mid-2000. While this final phase is expected to
yield improvements over the manufacturing systems currently in place, it should
be recognized that these current systems are not expected to be significantly
affected by any Y2K issues.
     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. This project has recently exceeded budget due
to unexpected costs related to data conversion and other issues associated with
implementation. As a result, the overall project budget has been revised to
reflect these additional costs, and now totals approximately $1.6 million.
Actual expenditures related to this project, through the first nine months of
1999, totaled approximately $1.1 million. This project encompasses the Company's
solution to Y2K issues as well as significant improvements in information
systems. As such, nearly all 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 are currently in the final stages of testing for this project,
and 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, thus 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 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


                                       11
<PAGE>   13

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. Based upon our current state of readiness, we do not anticipate any
significant disruptions due to internal Y2K issues. Further, 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 in the event of an unexpected failure of data processing systems
or microprocessor controlled manufacturing equipment. 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
have ordered additional supplies of raw material and critical operating supplies
and anticipate delivery of this material late in December. However, if our
customers' plans include a similar contingency, it is possible that we will use
such safety stock to satisfy our customers' requests that we, in turn, supply
them with safety stock. The Company is dependent upon its utility suppliers for
both heat and electricity and has concluded that adequate alternate sources are
not available. Accordingly, a disruption in the supply of natural gas or
electric power would significantly disrupt our operations. Although we have
received notification of Y2K compliance from our utility suppliers, we have also
developed plans to protect the Company's facilities from the effects of cold
weather in the event that utility service is disrupted for a short period of
time.

         Overall, the first nine months of 1999 have been successful for the
Company. Revenues have increased substantially. Earnings have improved
measurably despite significant costs incurred in connection with data processing
initiatives and a product recall. The Company's financial condition continues to
be sound and we expect the fourth quarter will be another successful quarter.



         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.
