1/4"-20 × 1/2" Stainless Steel Hex Head Serrated Flange Screw – 18‑8 with Wax

Designed for secure and corrosion‑resistant fastening, the 1/4"-20 × 1/2" hex head serrated flange screw is manufactured from durable 18‑8 stainless steel for excellent performance in indoor and outdoor environments. The integrated serrated flange helps resist loosening from vibration while eliminating the need for a separate washer. A wax coating reduces installation torque and helps prevent thread galling during assembly. Commonly used in machinery, equipment, and general industrial applications where reliable clamping and corrosion resistance are required.
