Utilizing our massive inventory of blanks, we manufacture fasteners inclusive of custom bolts, nuts, and screws for mining, heavy machinery, military, railroad construction, plus agricultural equipment applications. We work with sizes from 1/4″ to 4″ in diameter and lengths of up to 72″.

In addition to the distribution of standard fasteners, our reputation is also built upon the ability to meet your unique fastener requirements, such as extra-large and extra-long sizes. If you need to drill a hole through a part, fit an extra thread, add a special body diameter, or create a special pattern across the flats, we can do it for you. Blanks in every imaginable head style are stocked at our facility, and they can be modified according to your specifications.

Once we receive your fax or email containing the specification of fasteners, pricing and delivery details are dispatched within minutes. Manufacturing of custom fasteners is undertaken in our plant and deliveries can be made according to your scheduling or lay down needs – be it 24 hours, 7-10 days, or warehousing the parts plus shipping them to your location, when required. We are EDI-capable, and this enables us to provide fully integrated, dock-to-stock supply.

Chicago Nut & Bolt is A2LA-registered, compliant with the Fastener Quality Act, and ISO: 9001 2000 certified. This means you can count on us to meet all chemical and physical certifications you require. We test our fasteners using sophisticated equipment, including a state-of-the-art computerized system, which produces digitally certified tensile and yield test in accordance with ASTM requirements.

Not only do we manufacture and supply custom fasteners, but also package them according to your size, weight, container as well as labeling requirements, facilitating integration with your inventory plus handling systems. From special head marking to custom plating, every step adheres to strict controls to ensure product quality and integrity.
