5/16-18 Serrated Stainless Steel Flange Nut – Locking Hex Nut with Built-in Washer

This 5/16-18 Serrated Stainless Steel Flange Nut features a hexagonal body with an integrated washer flange and serrated teeth, providing a vibration-resistant, self-locking fastening solution.

The built-in flange eliminates the need for separate washers, while the serrated face bites into the surface to prevent loosening under vibration or dynamic loads.
