                           CHICAGO RIVET & MACHINE CO.
                 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 March 31, 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-month period ended March 31, 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, 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.

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

         Results for the first quarter of 2004 were somewhat encouraging.
Revenues and profits were both stronger than those of the prior three quarters,
although both fell short of the results achieved during the first quarter of
2003. In addition, demand for some of our products seems to be improving, albeit
modestly.

         Within the fastener segment, revenues amounted to $8,261,283, which is
slightly more than 1% below fastener segment revenues recorded in the first
quarter of 2003. However, while there was not a significant change in total
revenues within this segment, a larger portion of the total revenues was related
to the shipment of lower margin parts than was the case during the first quarter
of 2003. In addition, we incurred significant costs related to pre-production
approval for many new parts. While it is normal to incur such costs prior to
launching full production, it is unusual to have so many new parts in such a
short span of time. These costs amounted to approximately 4% of segment revenues
during the quarter, and were the primary reason that manufacturing costs
increased compared to the first quarter of 2003. We anticipate that revenues
from the shipment of these new parts will ramp up during the remainder of the
year and that this business will have a positive impact upon results.

         Revenues within the assembly equipment segment, improved slightly
compared with the first quarter of 2003 and amounted to $1,907,681. Gross
margins within this segment were essentially unchanged from the year earlier
period. Slight increases in the cost of raw materials were offset by modest
improvements in efficiency and a reduction in depreciation expense. Demand for
assembly equipment, while exhibiting some signs of improvement, remains soft.

         During the quarter, inventory balances increased slightly. In response
to concerns over the availability of raw materials, brought on by surging global
demand, we have increased our stock of raw materials used in the manufacture of
fasteners and are likely to further increase our supplies during the second
quarter, unless market conditions improve. Nevertheless, our overall inventory
levels are well below those of one year ago. The increase in the accounts
receivable balance at the end of the first quarter of 2004, compared to the end
of 2003 is due to higher sales during the current period and this increase was
not unexpected. Trade payables are slightly higher than one year ago, primarily
due to purchases associated with the new fastener segment business discussed
above. Management believes that the company's current cash, cash equivalents,
and operating cash flow will be sufficient to provide adequate working capital
for the foreseeable future.

         The economic recovery has finally begun to manifest itself in our
business. Certainly, conditions are not as robust as we would like, but what we
have seen is a welcome change from the recent past. Our markets remain extremely
competitive and industry capacity still exceeds demand, suggesting that margins
will remain under pressure. As previously reported, price and availability of
raw materials continues to be a concern. Global demand has caused material
prices to increase substantially and has had an impact upon material
availability. We have implemented temporary material surcharges in an effort to
recover these higher costs. To date, this effort has had mixed results, as many
customers have agreed to the surcharges; however, there are customers with whom
we have longer term supply agreements who have, so far, refused to accept these
surcharges. Our ability to recover these higher costs without losing market
share will have a significant impact on our success in the months ahead. We
continue to seek out new, profitable business and to focus on reducing costs to
remain competitive in our marketplace.

for the periods covered. Additional information is contained in our Form 10-Q,

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

which is cyclical and dependent on, among other things, consumer spending,
international economic conditions and regulations and policies regarding
international trade. Many of these factors are beyond our ability to control or
predict. Readers are cautioned not to place undue reliance on these
forward-looking statements. We undertake no obligation to publish revised
forward-looking statements to reflect events or circumstances after the date
hereof or to reflect the occurrence of unanticipated events.

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.
