This 5/16"-18 serrated flange nut is designed to provide a heavy-duty, vibration-resistant grip for your most demanding assemblies. The wide integrated flange eliminates the need for a separate washer by distributing the load evenly, while the aggressive serrations on the base dig into the mounting surface to prevent back-off. Precision-threaded for standard coarse 5/16" bolts, this nut offers a streamlined, self-locking solution that speeds up installation and ensures long-term joint integrity. These 5/16"-18 Flange Serrated Nuts are the same as the ones sold with the Pro Series accessories Shelf, Jack bracket, and Storage fenders etc.
For ITD-QUICK MOUNTS: 4 of the Bolts ITD-20096 and 4 of the nuts ITD-20157 per mount
