5/16"-18 x 2‑1/2" Stainless Steel 316 Hex Cap Screw, Full Thread, UNC Coarse

Manufactured from Type 316 stainless steel, the 5/16"-18 x 2‑1/2" UNC coarse‑thread hex cap screw is designed for applications that require extended length along with excellent corrosion resistance and dependable strength. The full‑thread design allows complete thread engagement across the entire shank, making it well suited for thicker components or multi‑layer assemblies where consistent clamping force is important. A standard hex head supports secure torque application using common hand tools, allowing efficient 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 reliable performance in environments exposed to moisture, chemicals, and corrosive conditions.
