Request Information

The 3/8-24 x 1 size in 18-8 stainless is suited to hex-head fastening where frames, brackets, or guards need serviceable external drive access. 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 washdown areas, clean-looking assemblies, and general plant environments. 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.
