1‑1/8"-7 x 3" Stainless Steel 304 B8 Heavy Hex Head Cap Screw, Full Thread, ASTM A193 Class 1

This 1‑1/8"-7 x 3" full‑thread heavy hex head cap screw is manufactured from 304 stainless steel and meets ASTM A193 Grade B8, Class 1 specifications, providing dependable strength and corrosion resistance for heavy‑duty industrial fastening applications. The full‑thread (FT) design allows continuous thread engagement across the entire shank, making it well suited for assemblies requiring uniform clamping force and flexibility in nut placement, particularly in large‑diameter, high‑load connections. The heavy hex head offers an increased bearing surface and enhanced wrench engagement, supporting accurate torque application during installation. Commonly used in flanged joints, piping systems, pressure connections, and equipment assemblies, this fastener resists rust, oxidation, and environmental exposure, delivering reliable long‑term performance in indoor, outdoor, and moderately corrosive environments.
