18-8 SS Flat Socket Cap Screw

ASTM F879 stainless flat socket head cap screws have a countersunk head with a flat top surface and hexagonal recess. The ASTM F879 specification covers the requirements for stainless steel hexagon flat countersunk head cap screws for use in applications requiring general corrosion resistance. Dimensional specifications are governed by ASME B18.3. Stainless flat socket head cap screws are commonly used in applications in which it is necessary to recess the head of the fastener flush with the surface. 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.
