This 3/8-24 x 3 1/2 18-8 stainless hex head cap screw is a size-specific listing for assemblies that use a nut or prepared tapped hole. 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 machine bases, structural brackets, and tapped-hole fastening points. External hex drive is useful when a wrench or socket can reach the head from the side and a counterbore would add unnecessary machining.

18-8 stainless steel is an 18% chromium and 8% nickel austenitic stainless material used for ordinary atmosphere, moisture exposure, washdown, and clean appearance. Cold Headers' catalog work is strongest where the requested size, material, and application details need a careful match.
