Grade C Locknuts
Grade C locknuts, also known as Stover or Top-Lock nuts, are one-piece, all-metal locknuts. They feature a conical crown with slightly distorted elliptical threads that create a tight mechanical grip when torqued. The result is a vibration-resistant connection that holds under heavy loads. These Grade C locknuts are finished with a Clear Cr3 Zinc and Wax coating for improved corrosion resistance.
