Spring Lock Washers for Slotted Bearing Nuts
Designed for use with bearing nuts, these lock washers have a conical shape that presses like a spring against bearings, bushings, gears, and pulleys to hold them in place on your threaded shaft or spindle. They also have an inner tab that sits in the shaft or spindle’s keyway to prevent the nut from loosening. Made of steel, they’re strong and flexible.
Spring lock washers with external teeth grip components using their teeth, in addition to spring tension.
DIN 462 and DIN 5406 washers meet international standards for lock washer dimensions. Pair DIN 462 washers with DIN 1804 bearing nuts, and DIN 5406 washers with DIN 981 bearing nuts.

Wedge Lock Washers
Also known as NORD-LOCK® washers, these two-piece washers provide more locking power than split, tooth, and spring lock washers. Wedges on the inside lock the two pieces together, and serrations on the exterior grip surfaces to resist loosening from high vibration and shifting. Washers are reusable.
Zinc-flake-coated steel washers are corrosion resistant in wet environments.
