At a Glance
Overview
FF-S-92 covers machine screws — general-purpose externally threaded fasteners intended for use with a mating nut or in a tapped hole, in slotted, cross-recessed (Phillips-type), or hexagon head configurations. Machine screws are typically smaller and lighter-duty than the cap screws covered by FF-S-85 and FF-S-86, and are widely used across electronics, panel, and general assembly work rather than heavy structural joints.
The current Revision D was published June 8, 2020, continuing the specification's long-running coverage of these general-purpose fastener types. Materials commonly include carbon steel (with black oxide or cadmium/zinc plating) and corrosion resistant steel for wet or corrosive environments.
