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

Manufactured from 316 stainless steel and meeting ASTM A193 Grade B8M, Class 1 specifications, the 3/4"-10 x 4‑3/4" heavy hex head cap screw is engineered for corrosion‑resistant fastening in high‑load industrial and structural applications. The partial‑thread (PT) design includes an extended unthreaded shank that enhances shear strength and promotes efficient load transfer across bolted joints, making it well suited for flanged connections and thick material assemblies. Its 4‑3/4" length provides additional reach for deeper engagement, while the heavy hex head offers increased bearing surface and improved wrench engagement for precise torque control during installation. Commonly specified for 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.
