3/8-24 x 1/2 18-8 Stainless Steel Hex Head Cap Screw is an externally driven fastener for wrench or socket installation from the side of the head. 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 outdoor hardware, equipment covers, and access panels. Stainless-on-stainless threads can gall when run down fast or dry; moderate installation speed and thread lubricant are prudent on larger diameters.

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.
