About Hex Head Screws and Bolts

Fully Threaded

Partially Threaded

Choose these screws for their adherence to strict military standards for material and construction. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. Dimensions meet Fed. Spec. FF-S-85 specifications. Length is measured from under the head.

Match the thread spacing of mating components. Fine threads are closely spaced to prevent loosening from vibration.
