1-8 x 1 1/2 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 industrial equipment, exposed assemblies, and wrench-access locations. 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' catalog work is strongest where the requested size, material, and application details need a careful match.
