7/8"-9 x 2‑3/4" Stainless Steel 304 B8 Heavy Hex Head Cap Screw, Partial Thread, ASTM A193 Class 1

This 7/8"-9 x 2‑3/4" heavy hex head cap screw is manufactured from Type 304 stainless steel and produced in accordance with ASTM A193 Grade B8, Class 1, providing dependable corrosion resistance and mechanical strength for industrial fastening applications. The partial‑thread (PT) configuration incorporates an unthreaded shank that enhances shear capability and promotes proper alignment in bolted joints, making it especially suitable for flanged connections and structural assemblies. Its extended length supports secure fastening through thicker components, while the heavy hex head offers increased bearing surface and improved wrench engagement for controlled torque application. Commonly used in piping systems, pressure connections, equipment mounting, and structural fabrication, this fastener delivers reliable resistance to rust, oxidation, and environmental exposure for long‑term performance in indoor, outdoor, and moderately corrosive environments.
