Stainless Steel Socket Head Cap Screws
18-8 Stainless Steel Knurled Head Socket Cap Screws
A socket cap screw is a fastener driven with a socket wrench, and are knurled. Socket cap screws made of stainless steel are used primarily for long lasting applications, due to its corrosion-resistant nature and durability. Scratching or burring the metal will not create surface rust as the corrosion resistance exists within the metal itself. Stainless steel is a soft metal due to the low carbon content, therefore most stainless steel bolts are cold-formed and not heat treated or thru-hardened.
