ASTM F880 stainless steel socket set screws are a headless fastener threaded its entire length (except for the point) used commonly for fastening mated parts such as a shaft and collar. The F912 specification covers the requirements for austenitic grade stainless steel socket-set screws. Dimensional specifications are governed by ASME B18.3. The socket set screw's headless design allows the fastener to sit flush, or inset, into the threaded part. Stainless steel fasteners are commonly used in applications that require general atmospheric corrosion resistance, such as chemical and food processing equipment. Stainless steel has a higher corrosion resistance than carbon steel.
