Section 1 – Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

This report for the year ended December 31, 2023 has been prepared by management of Chicago Rivet & Machine Co. (the “Company,” “we,” “us,” and “our”) to comply with Section 13(p) of the Securities Exchange Act of 1934, as amended, and Rule 13p-1 (the “Rule”) promulgated thereunder. The Rule was adopted by the Securities and Exchange Commission (“SEC”) as required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and imposes certain reporting obligations on SEC registrants whose manufactured products contain so-called “conflict minerals” that are necessary to the functionality or production of those products. As used in this report, the term “conflict minerals” includes columbite-tantalite, cassiterite, gold, wolframite, and their derivatives tantalum, tin and tungsten.

A copy of this report is made available on our website at www.chicagorivet.com, under the heading “Investor Relations”. The website and the information accessible through it are not incorporated into this specialized disclosure report.

Company Overview

The Company operates in two segments of the fastener industry: fasteners and assembly equipment. The fastener segment consists of the manufacture and sale of rivets, cold-formed fasteners and parts and screw machine products. The assembly equipment segment consists primarily of the manufacture of automatic rivet setting machines, automatic assembly equipment and parts and tools for such machines.

For the year ended December 31, 2023, we determined that the plating of certain products in the fastener segment contained tin and that our rivet setting machines include electronic components that also may contain conflict minerals. As required by the Rule, we conducted a reasonable country of origin inquiry to determine whether those conflict minerals originated in the Democratic Republic of the Congo or an adjoining country (collectively, “Covered Countries”).

Reasonable Country of Origin Inquiry

Because there are multiple tiers between us and the mines from which conflict minerals are sourced, we rely on the information provided by our direct suppliers to determine the origin of the conflict minerals contained in the components and materials supplied to us, including the conflict minerals provided to our suppliers from sub-tier suppliers. Accordingly, the methods we used to determine the origin of those conflict minerals included the following:

Results

All of our suppliers of tin included in our fastener products responded to our surveys and indicated that such tin did not originate in the Covered Countries. While we did not receive survey responses from all of our suppliers of the electronic components included in our rivet setting machines, none of the supplier responses received to date have indicated that the conflict minerals contained in those components originated in the Covered Countries. Accordingly, based on our reasonable country of origin inquiry, we have concluded that we have no reason to believe that the conflict minerals contained in our products may have originated in the Covered Countries.
