Specify 8-32 x 3/8 18-8 Stainless Steel Hex Head Cap Screw when thread, length, material, and external hex drive must match an existing bill of materials. In this size range it is treated as a hex head machine screw, with the hex head driven by external tooling rather than an internal socket.

Common application reviews include stainless hardware packages, controls, and mounting plates. 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 has supplied specialty fasteners since 1962 and supports exact-size sourcing for hard-to-find industrial hardware.
