For drawings calling out 1/2-13 x 1 1/8, this 18-8 stainless hex head fastener supports assemblies where top-drive clearance is not required. 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. When the design calls for a recessed counterbored fastener or tighter tool clearance, compare 18-8 Socket Head Cap Screws.

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.
