                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)


1. In the opinion of the Company, the accompanying unaudited interim financial
statements contain all adjustments necessary to present fairly the financial
position of the Company as of June 30, 2004 and December 31,2003 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 on a portion of its operations. 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 and six-month period ending June 30,
2004 are not necessarily indicative of the results to be expected for the year.

3. The Company extends credit on the basis of terms that are customary within
our markets to various companies doing business primarily in the automotive
industry. 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, 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.

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

         Overall, results for the second quarter of 2004 were positive. For the
quarter, revenues increased by approximately $232,000, and net income grew by
approximately $165,000, compared with the second quarter of 2003. Despite the
relatively strong second quarter results, net income for the first six months of
2004 trails that of 2003 by about $10,000.

         In 2004, second quarter revenues within the fastener segment were 6%
higher than in the second quarter of 2003. In addition to increased volumes
during the second quarter, the Company benefited from reductions in expenditures
for tooling and repairs and maintenance. These benefits were partially offset by
significant increases in the cost of raw materials. Our efforts to recover these
higher costs have included price increases and the implementation of raw
material surcharges. However, prices for nearly all metals increased during the
quarter, and our suppliers recently announced an additional price increase for
steel wire and rod, our primary raw materials. The net, unrecovered cost
associated with higher raw material prices was approximately $180,000 during the
second quarter and $305,000 for the first six months. We have seen no indication
that prices for raw materials will decline in the near term, and we are
vigorously continuing our efforts to recover these higher costs.

         For the first six months, fastener segment revenues are 2% above
those recorded in the first six months of 2003. Indirect labor and repairs and
maintenance expense were lower during 2004 than during the first six months of
2003. The company incurred significant tooling costs late in 2003 and early in
2004 in connection with pre-production approval for a number of new parts. While
these costs are behind us, and the new parts are beginning to go into
production, the impact of these higher costs in the first quarter of 2004
contributed to year to date tooling costs being disproportionately high for the
first half of 2004. Raw material costs are also higher than during the first
half of 2003 due to the price increases discussed above, and similar increases
that were incurred in the first quarter of 2004.

         Weak demand for our products within the assembly equipment segment
contributed to an 11% decline in revenues within this segment during the second
quarter of 2004 compared to the second quarter of 2003. Reductions in indirect
labor and depreciation expense partially offset this decline in revenues. Raw
material costs have also increased within this segment, although the impact has
not been as significant as in the fastener segment. On a year to date basis,
revenues within this segment trail last year by nearly 5%. As was the case in
the second quarter, year to date reductions in indirect labor and depreciation
expense were not sufficient to offset the impact of lower sales revenues and
higher raw material prices.

         Selling and administrative expenses have declined approximately $52,000
in 2004 compared to 2003, even though these expenses increased by approximately
$46,000 during the second quarter of 2004. The year to date decline primarily
relates to lower depreciation on office equipment. During the second quarter of
2004, commissions expense increased approximately $18,000 compared to 2003 due
to higher sales in the quarter, and profit sharing expense increased $26,000,
due to improved profitability.

         Total inventory levels at the end of the second quarter were slightly
below those at the beginning of the year, although raw material inventories are
somewhat higher than at the beginning of the year. We anticipate continuing to
carry somewhat more raw materials as availability continues to be of concern in
the face of rising global demand for basic raw materials. Accounts receivable
declined slightly during the quarter and are at levels consistent with recent
sales volumes. With the exception of trade payables, the company has no
outstanding debt. The Company placed an order for new equipment to be used in
the manufacture of fasteners, valued at approximately $690,000, for which
delivery is expected in the third quarter of 2004. The Company's $1.0 million
dollar line of credit was extended through May 2005, and as of June 30, 2004 it
remained unused. Management believes that the Company's current cash, cash
equivalents, operating cash flow and available line of credit will be sufficient
to provide adequate working capital for the foreseeable future.

         While general economic conditions continue to improve, our business has
not enjoyed a proportionate improvement. This is especially true within the
assembly equipment segment where demand for new assembly equipment and for
perishable tooling remains weak. While fastener sales have shown some
improvement, the lack of a similar improvement in demand for assembly equipment
is troubling and may be an indication that demand for these products will not
return to levels enjoyed in the past. We continue to be concerned with the
escalating price of raw materials and have some continuing uncertainty with
respect to supply availability. Although the market for fasteners has shown some
improvement, especially compared to the recent past, excess market capacity
continues to limit our pricing ability,





                                       10

and we expect margins will remain under pressure as long as these conditions
persist. On the positive side, efforts to win new business have met with some
success, and we will continue our efforts in that regard.


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, our ability to maintain our
relationships with our significant customers; increased global competition;
increases in the prices of, or limitations on the availability of, our primary
raw materials; or a downturn in the automotive industry, upon which we rely for
sales revenue, and which is cyclical and dependent on, among other things,
consumer spending, international economic conditions and regulations and

Item 4. Controls and Procedures.

         (a) Disclosure Controls and Procedures. The Company's management, with
the participation of the Company's Chief Executive Officer and Chief Financial
Officer, has evaluated the effectiveness of the Company's disclosure controls
and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under
the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of the
end of the period covered by this report. Based on such evaluation, the
Company's Chief Executive Officer and Chief Financial Officer have concluded
that, as of the end of such period, the Company's disclosure controls and
procedures are effective in recording, processing, summarizing and reporting, on
a timely basis, information required to be disclosed by the Company in the
reports that it files or submits under the Exchange Act.

         (b) Internal Control Over Financial Reporting. There have not been any
changes in the Company's internal control over financial reporting (as such term
is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the
fiscal quarter to which this report relates that have materially affected, or
are reasonably likely to materially affect, the Company's internal control over
financial reporting.
