Fastenal is one of the largest industrial distributors in the US, supplying goods used in both the final manufactured product and the running of the factories of its many customers. The company's roots are in the distribution of fasteners (screws, nuts and bolts) but today the business excels at distributing other categories of industrial products such as safety equipment and tools.

Fastenal offers its customers innovative distribution solutions such as industrial vending, vendor-managed inventory and an on-premise store to improve inventory availability and reduce supply chain costs.
