Description
An externally threaded fastener with unified threads, a cylindrical head with a flat chamfered top surface, knurled cylindrical sides, and hexagonal recess, made from stainless steel.
Application/ Advantages
Although stainless socket cap screws have significantly less tensile and yield strength than alloy sockets, they have superior corrosion resistance. They retain their mechanical and performance capabilities at higher than ambient temperatures.
Hardness
Rockwell B80 minimum.
