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

This 3/4"-10 x 4" heavy hex head cap screw is manufactured from Type 304 stainless steel and meets ASTM A193 Grade B8, Class 1 requirements, providing reliable strength and corrosion resistance for demanding industrial and structural applications. The partial‑thread (PT) configuration incorporates an unthreaded shank section that enhances shear strength and improves alignment in bolted joints, making it especially suitable for structural connections, flanges, and thick material stacks. The extended 4" length supports deep engagement in heavy assemblies, while the heavy hex head offers increased bearing surface and superior wrenching control for accurate torque application. Designed for use in piping systems, equipment mounting, and industrial fabrication, this fastener delivers consistent performance and long service life in indoor, outdoor, and moderately corrosive environments.
