Nuts and Washers
FSC 5310: Nuts and Washers
Federal Supply Class (FSC) 5310 covers nuts and washers, the threaded and bearing components that complete bolted and screwed joints. The catalog includes active, obsolete, and last-time-buy items built to NAS, AN, MS, and MIL-SPEC specifications.
Nuts engage threaded fasteners to clamp joints, while washers spread load and protect surfaces. Together they set and maintain the preload that holds a joint secure.
Common types include hex nuts, lock nuts, castle nuts, and wing nuts, along with flat, lock, and spring washers. Materials include alloy steel, stainless steel, and brass with finishes such as cadmium and zinc.
