3/8"-16 x 4" Stainless Steel 316 Hex Cap Screw, Full Thread, UNC Coarse

Manufactured from Type 316 stainless steel, the 3/8"-16 x 4" UNC coarse‑thread hex cap screw is intended for long‑length fastening applications where high corrosion resistance and dependable mechanical strength are required. The full‑thread configuration provides continuous thread engagement along the entire shank, ensuring uniform clamping force and secure joint integrity in thick materials or multi‑layer assemblies. A standard hex head allows consistent torque application using common hand tools, supporting controlled and repeatable installation. Frequently used in marine hardware, chemical processing equipment, food‑grade systems, and outdoor industrial assemblies, this fastener delivers extended service life and reliable performance in environments exposed to moisture, chemicals, and corrosive conditions.
