1/2-20 x 3/4 18-8 Stainless Hex Head Cap Screw

1/2-20 x 3/4 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. Use it through a clearance hole with a nut or into a prepared tapped hole when the drawing calls for a stainless hex-head fastener.

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.
