3/4"-10 x 3‑1/4" Stainless Steel 304 B8 Heavy Hex Head Cap Screw, Partial Thread, ASTM A193 Class 1

This 3/4"-10 x 3‑1/4" heavy hex head cap screw is manufactured from 304 stainless steel and complies with ASTM A193 Grade B8, Class 1, providing reliable mechanical strength and corrosion resistance for industrial and structural fastening. The partial‑thread (PT) design includes an unthreaded shank section that improves shear capacity and promotes proper alignment in bolted joints, making it well suited for structural connections and flanged assemblies. Its extended length supports fastening through thicker materials, while the heavy hex head offers increased bearing surface and enhanced wrenching control for accurate torque application. Commonly used in piping systems, equipment supports, and industrial fabrication, this fastener delivers dependable performance and long service life in indoor, outdoor, and moderately corrosive environments.
