1/2"-13 × 3" Stainless Steel Hex Head Serrated Flange Screw – 18‑8 with Wax

Designed for reliable fastening in demanding assemblies, the 1/2"-13 × 3" hex head serrated flange screw is manufactured from durable 18‑8 stainless steel for excellent corrosion resistance in indoor and outdoor environments. The integrated serrated flange provides superior grip and resistance to loosening under vibration, eliminating the need for a separate washer. A wax coating is applied to reduce installation torque and help prevent galling during assembly. Commonly used in industrial equipment, machinery, and structural applications where strength, corrosion resistance, and secure fastening are required.
