3/8"-16 x 3‑1/2" Stainless Steel 316 Hex Cap Screw, Full Thread, UNC Coarse

Manufactured from Type 316 stainless steel, the 3/8"-16 x 3‑1/2" UNC coarse‑thread hex cap screw is intended for extended‑reach fastening applications where corrosion resistance and structural reliability are essential. The full‑thread design provides uninterrupted thread engagement along the entire shank, supporting consistent clamping force and secure joint integrity in thicker materials or multi‑layer assemblies. A standard hex head allows efficient torque application with common hand tools, enabling controlled and repeatable installation. Commonly specified for marine hardware, chemical processing equipment, food‑grade systems, and outdoor industrial assemblies, this fastener delivers long service life and dependable performance in environments exposed to moisture, chemicals, and corrosive conditions.
