Collection: Screws

Mil-spec screws cover machine screws, structural screws and set screws — precision-threaded, material-controlled, and inspected to a military drawing rather than a commercial standard. Head styles track the application: 100° flush heads for aerodynamic surfaces, pan and fillister heads for equipment mounting, socket heads for high-strength internal wrenching.

High-volume families include MS24693/MS24694 cross-recessed machine screws, MS27039 structural pan-head screws, NAS1351/NAS1352 socket-head cap screws, AN565 set screws, and the NAS514 and NAS1102 flush-head series. Materials range from cadmium-plated carbon and alloy steel to 18-8 stainless, with A286 (NAS1351N, NAS1102E) for elevated-temperature joints. Drive recesses — Phillips, offset cruciform, Torq-Set, hex socket — are standardized as well, because cam-out damage starts with the wrong bit.

Every lot ships with a Certificate of Conformance; heat-lot traceable mill material reports are available on request.
