3/4"-10 x 5" Stainless Steel 316 B8M Heavy Hex Head Cap Screw, Partial Thread, ASTM A193 Class 1

Manufactured from 316 stainless steel and compliant with ASTM A193 Grade B8M, Class 1, the 3/4"-10 x 5" heavy hex head cap screw is engineered for corrosion‑resistant fastening in high‑load industrial and structural applications. The partial‑thread (PT) configuration features an extended unthreaded shank that enhances shear strength and improves load distribution in stressed bolted joints, making it especially effective for flanged connections and thick material assemblies. Its 5" length provides deep engagement through substantial components, while the heavy hex head offers increased bearing surface and improved wrench leverage for accurate torque application. Commonly used in marine environments, chemical processing equipment, pressure systems, and outdoor structural installations, this fastener delivers dependable performance and long service life in corrosive and moisture‑exposed conditions.
