1-8 x 5 1/2 18-8 Stainless Steel Hex Head Cap Screw is built for conventional hex-head fastening through clearance holes or into tapped parts. In this size range it is treated as a hex head cap screw, with the hex head driven by external tooling rather than an internal socket.

Common application reviews include maintenance replacement work, field repairs, and production equipment. The hex head format keeps the drive outside the workpiece, which can simplify inspection and service in exposed assemblies.

18-8 stainless steel is an 18% chromium and 8% nickel austenitic stainless material used for ordinary atmosphere, moisture exposure, washdown, and clean appearance. When standard catalog searches are too broad, Cold Headers supports precise sourcing for stainless fasteners and related socket products.
