Locknuts and lock washers are precision retaining devices for bearing, power transmission and other machinery and equipment assemblies. Locknuts and lock washers secure bearings, gears, and other power transmission products to shafts and spindles. Locknuts and lock washers are available in a variety of configurations and materials including hardened steel, left handed, metric, stainless, and aluminum. Lock nuts and washers are available in multiple precision classes and styles depending on application requirements.

Lock washers are used to resist loosening of bolted joints. There are essentially two types: spring action and tooth.

Spring action lock washers include split (helical spring), which are also called spring washers. These washers, placed under the nut or screw head, compress as the fastener is tightened and the spring-back tension deters loosening. Also, because of their spring-like take-up action, split lock washers can compensate for slight material wear. But because spring types flatten when tightened, their "locking" action doesn't come into play until the fastener has slightly loosened. Use regular for Grade 2 hex cap screws and high strength alloy steel for Grade 5 and 8 hex cap screws.
