Overview
The hex head cap screw 7/16-14 x 2-1/2″ in 18-8 stainless steel provides reliable fastening for equipment requiring durable, corrosion-resistant hardware. These fully threaded screws feature a hex head design that accommodates standard wrenches and sockets for quick installation and removal. The 18-8 (304-grade) stainless steel construction resists rust and degradation in harsh, humid, or chemically demanding environments.
