5/16"-18 x 2‑3/4" Stainless Steel 316 Hex Cap Screw, Full Thread, UNC Coarse

Manufactured from Type 316 stainless steel, the 5/16"-18 x 2‑3/4" UNC coarse‑thread hex cap screw is intended for longer‑reach fastening applications that require superior corrosion resistance and consistent mechanical strength. The full‑thread configuration provides complete thread engagement along the entire shank, supporting uniform clamping force in thicker materials or multi‑layer assemblies. A standard hex head allows dependable torque application using common hand tools, ensuring efficient and repeatable installation. Frequently used in marine hardware, chemical processing equipment, food‑grade systems, and outdoor industrial assemblies, this fastener delivers long service life and reliable performance in environments exposed to moisture, chemicals, and corrosive conditions.
