1"-8 x 2‑1/2" Stainless Steel 304 B8 Heavy Hex Head Cap Screw, Full Thread, ASTM A193 Class 1

This 1"-8 x 2‑1/2" full‑thread heavy hex head cap screw is manufactured from 304 stainless steel and meets ASTM A193 Grade B8, Class 1 requirements, providing reliable strength and corrosion resistance for heavy industrial and structural fastening applications. The full‑thread configuration allows complete thread engagement along the shank, making it ideal for assemblies where uniform clamping force and flexible nut positioning are required. The heavy hex head offers a larger bearing surface and enhanced wrench contact, supporting controlled torque application in high‑load installations. Commonly used in flanged joints, piping systems, pressure connections, and equipment assemblies, this fastener delivers excellent resistance to rust, oxidation, and environmental exposure, ensuring consistent performance and long service life in indoor, outdoor, and moderately corrosive environments.
