1"-8 x 2‑3/4" Stainless Steel 316 B8M Heavy Hex Head Cap Screw, Full Thread, ASTM A193 Class 1

Manufactured from 316 stainless steel and produced to ASTM A193 Grade B8M, Class 1, the 1"-8 x 2‑3/4" heavy hex head cap screw is designed for corrosion‑resistant fastening in industrial and structural applications requiring reliable strength and durability. The full‑thread (FT) configuration provides continuous thread engagement along the entire shank, supporting uniform clamping force and secure joint integrity where consistent load distribution is critical. The heavy hex head offers a larger bearing surface and enhanced wrench engagement compared to standard hex heads, allowing controlled torque application during installation. Commonly specified for marine environments, chemical processing equipment, pressure systems, and outdoor structural assemblies, this fastener delivers dependable performance and long service life in corrosive and moisture‑exposed conditions.
