3/8"-16 × 2‑1/2" Stainless Steel Hex Head Serrated Flange Screw – 18‑8 with Wax

Designed for secure, corrosion‑resistant fastening, the 3/8"-16 × 2‑1/2" hex head serrated flange screw is manufactured from durable 18‑8 stainless steel for dependable performance in indoor and outdoor environments. The integrated serrated flange provides strong resistance to loosening caused by 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 extended grip length, reliable clamping strength, and corrosion resistance are required.
