7/8"-9 x 5" Stainless Steel 304 B8 Heavy Hex Head Cap Screw, Partial Thread, ASTM A193 Class 1

This 7/8"-9 x 5" heavy hex head cap screw is manufactured from 304 stainless steel and conforms to ASTM A193 Grade B8, Class 1, making it suitable for long‑reach industrial and structural fastening applications where corrosion resistance is critical. The partial‑thread (PT) construction incorporates a long, smooth shank that enhances shear strength and ensures proper load transfer in thick or high‑stress bolted joints, while the extended 5" length allows secure fastening through deep material sections. The heavy hex head provides increased bearing area and improved wrenching leverage, supporting accurate torque application during installation. Commonly specified for piping systems, pressure assemblies, equipment foundations, and heavy structural fabrication, this fastener delivers reliable resistance to rust, oxidation, and environmental exposure for consistent, long‑term performance in indoor, outdoor, and moderately corrosive environments.
