1/2"-13 x 3‑1/2" Stainless Steel 316 Hex Cap Screw, Full Thread, UNC Coarse

Manufactured from Type 316 stainless steel, the 1/2"-13 x 3‑1/2" UNC coarse‑thread hex cap screw is intended for longer‑grip fastening applications where superior corrosion resistance and consistent structural performance are required. The full‑thread design provides uninterrupted thread engagement along the entire length of the fastener, supporting uniform clamping force and secure joint integrity in thick or multi‑layer assemblies. A standard hex head allows dependable torque application with common hand tools, enabling controlled and repeatable installation. Frequently used in marine construction, chemical processing equipment, food‑grade systems, and outdoor industrial assemblies, this fastener delivers long service life and reliable strength in environments exposed to moisture, chemicals, and corrosive conditions.
