3/8-16 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 tank supports, fixture plates, and stainless brackets. 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. Cold Headers serves maintenance and production needs where exact-size stainless hardware matters more than generic substitution.
