                          CHICAGO RIVET & MACHINE CO.
            NOTES TO THE CONDENSED 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, 2006 (unaudited) and December 31, 2005
(audited) and the results of operations and changes in cash flows for the
indicated periods.

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,
2006 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 and contract disputes, 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.

5. On May 30, 2006 the Board of Directors of Chicago Rivet & Machine Co.
determined that the Company would close its fastener operation in Jefferson,
Iowa and transfer production activities to its facility in Tyrone, Pennsylvania.
The Jefferson, Iowa facility had been operating below capacity, and the Company
determined to close the facility as part of its cost savings efforts. While the
exact timing is unknown at this time, it is expected that the transfer will be
substantially complete by December 31, 2006.

The Company recorded a one-time charge of $400,401 relating to termination
benefits in connection with the closing of the Jefferson facility. The Company
does not anticipate that it will record a material charge related to asset
impairment as a result of this closing. Additional costs associated with the
relocation of equipment and closing and disposal of the facility are
anticipated, but the amount and timing of such costs are not known at this time.

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

     Results for the second quarter of 2006, as well as the current year to
date, reflect continued improvement over the results for the same periods last
year. For the quarter, sales have increased $993,000, bringing the increase for
the year to $1,851,000. The combination of improved sales volume and the
reduction in certain expenses has helped the Company to report net income of
$469,000 in the quarter and $858,000 for the first half of the year, compared to
net losses in the year earlier periods.

     Within the fastener segment, revenues increased from $8,445,000 to
$9,529,000, or 12.8%, during the second quarter of 2006. The increase in sales,
combined with a reduction in tooling expense of $353,000, contributed to an
increase in gross margin of approximately $1,234,000 compared to the second
quarter of 2005. Two factors contributed to the tooling reduction in 2006: the
first was the greater than normal expenditure for tool development during 2005
when parts were being designed prior to shipment to customers, the second was
the overall longer life on certain tools during the current year. Margins were
further improved due to higher production volume in the current year that has
allowed for greater utilization of labor and overhead costs compared to 2005.

     For the first six months, fastener segment revenues increased by
$1,918,000, or 11.4%, from $16,792,000 to $18,710,000. Gross margins for the
first six months of 2006 increased $1,790,000 compared to the first half of
2005. Higher sales volume was the primary factor behind the improvement in
margins. Tooling expense has declined $537,000 year to date for the reasons
outlined above.

     Revenues within the assembly equipment segment totaled $1,528,000 in the
second quarter of 2006, a decline of $92,000, or 5.7%, compared to the second
quarter of 2005, when revenues were $1,620,000. Demand for our products in this
segment continues to show weakness after rebounding slightly in the first
quarter. Gross margins for this segment improved approximately $27,000 in the
quarter, however, as headcount reductions that took place during the second
quarter of 2005 have resulted in lower payroll and related benefits in the
current year. For the first six months of 2006, revenues in this segment
amounted to $3,288,000, a decline of approximately $67,000, or 2%, compared to
the first six months of 2005. The current year to date reduction in payroll and
related benefits offset the year to date decline in revenues and resulted in an
improvement in gross margin of approximately $23,000.

     Selling and administrative expenses for the second quarter of 2006 were
approximately $46,000 lower than during the second quarter of 2005. Professional
services were $85,000 lower in the quarter primarily due to procedures performed
in 2005 related to compliance with the Sarbanes-Oxley Act of 2002, while legal
fees declined $35,000 due to litigation and other matters resolved in 2005.
Further, salaries and wages declined $42,000 during the second quarter due to
reduced headcount. These decreases were partially offset by an increase in
profit sharing expense of $125,000 resulting from more profitable operations in
the current year. On a year to date basis, selling and administrative expenses
declined $166,000 compared to the first six months of 2005. Professional
services were $217,000 lower, legal fees declined $108,000 and salaries and
wages declined by $29,000, for the reasons stated above. These reductions were
partially offset by profit sharing expense which has increased by $190,000 due
to the return to profitability in the current year.

     During May of the current year, a decision was made to close our fastener
operation located in Jefferson, Iowa and transfer production activities to our
facility in Tyrone, Pennsylvania to better utilize manufacturing capacity.
Approximately $400,000 was accrued during the quarter for one-time termination
benefits related to the closing. While the exact timing is unknown, the process
of transferring activities is underway and is expected to be substantially
completed by December 31, 2006. Additional costs associated with the relocation
of equipment and closing and disposal of the facility are anticipated, but the
amount and timing of such costs are not known at this time.

     Working capital at June 30, 2006 amounted to $15 million, an increase of
$.2 million from the beginning of the year. Holdings in cash, cash equivalents
and certificates of deposit amounted to $4.8 million at the end of the second
quarter, a year to date decline of $.9 million, which is approximately equal to
capital outlays in 2006 that have been primarily to expand our fastener segment
production capabilities. Offsetting this decline, accounts receivable balances
have increased by $1.9 million this year. This increase is expected as sales in
the latter portion of the second quarter typically exceed those towards the end
of the calendar year. Current liabilities are $.6 million higher than at the
beginning of the year, primarily due to the accrual of termination benefits
related to the Jefferson, Iowa plant closing.

     The Company has a $1.0 million line of credit, which expires May 31, 2007.
This line of credit remains unused. Management believes that current cash, cash
equivalents, operating cash flow and the available line of credit will provide
adequate working capital for the foreseeable future.

     The second quarter of 2006 reflects the continued improvement in customer
demand that began in the first quarter. Along with the 9.9% improvement in
sales, we were able to once again realize improved gross margins on a comparable
quarter basis due to a significant reduction in tooling expense and greater
utilization of plant capacity. However, we rely on the domestic automotive
industry for revenue, and that reliance keeps us cautious as we look ahead. The
domestic automotive industry has been declining for some time as it faces
challenges related to labor issues, over-capacity and lower-cost foreign
competition. Overall, raw material costs in the first half of 2006 receded
slightly compared to the first half of 2005. However, some prices have increased
again recently, and they remain significantly higher than historical levels.
Competition for available market share continues to restrict our ability to
raise prices. Although costs associated with Sarbanes-Oxley compliance have been
lower thus far in 2006, final regulations as they relate to companies our size
may change, resulting in further expenses that cannot be estimated at this time.
While we are pleased with the return to profitability we have achieved in
the first six months of 2006, the competitive landscape remains challenging, and
we must continue to focus on controlling costs while investing wisely for the
future.

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, those disclosed under "Risk Factors" in our
Annual Report on Form 10-K and in the other filings we make with the United
States Securities and Exchange Commission. These factors, include among other
things: conditions in the domestic automotive industry, upon which we rely for
sales revenue, the intense competition in our markets, the concentration of our
sales to two major customers, the price and availability of raw materials, labor
relations issues, losses related to product liability, warranty and recall
claims, costs relating to environmental laws and regulations, the loss of the
services of our key employees and difficulties in achieving expected cost
savings. 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.
