Manufacturing Services

At Fastenal Manufacturing, we don't make the common fasteners found on your local Fastenal store shelf — We Make the Unavailable Part Available. That includes everything from complex machined parts and high-volume production fasteners, to large-diameter bolts and complete stud assemblies. Through our nine global manufacturing locations, we produce more than 70,000 jobs per year — each one a solution for a customer in need.

The video below contains more information about the four "pillars" of Fastenal Manufacturing and how we can meet your needs for custom-manufactured parts with unmatched speed, precision, and quality.

Fastenal has been hot-forging custom parts for more than 20 years, and today our Cardinal hot forging division encompasses three facilities, more than 20 experienced forge operators, and a spectrum of presses and materials. With millions of dollars in bolt blank inventory, hundreds of stock dies for common heading needs, and the ability to produce custom tooling within 24 hours for unique head geometries, we're ready to put your specialty bolt project into production.
