5/16-18 x 1 3/4 18-8 Stainless Steel Hex Head Cap Screw is built for conventional hex-head fastening through clearance holes or into tapped parts. 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 stainless hardware packages, controls, and mounting plates. 18-8 stainless is not a graded or heat-treated fastener; where certified high clamp loads govern, a graded steel hex bolt is the better tool.
18-8 stainless steel is an 18% chromium and 8% nickel austenitic stainless material used for ordinary atmosphere, moisture exposure, washdown, and clean appearance. For production, repair, and distributor sourcing, Cold Headers can help confirm the exact diameter and length before quoting.
