3/8-24 x 5/16 18-8 Stainless Steel Hex Head Cap Screw provides a familiar wrench-driven head for plant equipment and field replacement work. 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 food processing skids, washdown equipment, and packaging lines. 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.
