5/16-18 Serrated Flange Nut Zinc Plated. This product is a hex nut with a serrated bearing surface beneath the flange that displaces material on the mating surface when the nut is torqued down, forming a connection that resists loosening. These nuts will often see use in applications where vibration is an issue, like on vehicles or industrial machines.
Serrated flange nuts serve as a more-than-suitable replacement for lock washers, and you could even consider them an improvement. Like washers, the nuts help to distribute pressure more evenly throughout the surface. However, they also offer a tighter overall hold than washers, as serrated flange nuts require a significantly higher amount of torque to remove than install due to how they bite into the mating surface. The zinc coating on these flange nuts increases corrosion resistance, as it will hold off excessive moisture and prevent rust.
