1/2"-13 × 2‑1/2" Stainless Steel Hex Head Serrated Flange Screw – 18‑8 with Wax

Designed for durable fastening in demanding assemblies, the 1/2"-13 × 2‑1/2" hex head serrated flange screw is manufactured from 18‑8 stainless steel for excellent corrosion resistance in indoor and outdoor environments. The integrated serrated flange provides strong resistance to loosening from vibration while eliminating the need for a separate washer. A wax coating is applied to reduce installation torque and help prevent thread galling during assembly. Commonly used in machinery, equipment, structural, and industrial applications where corrosion resistance and secure clamping are required.
