Wedge Lock Washers

Buy Wedge Lock Washers Online in Australia

A wedge lock washer is a pair of washers with cam faces that lock together when the bolt is tightened, so the joint is held by the washers rather than by spring force. They are used where a spring or tooth washer is not enough, such as vibrating plant and equipment. AIMS Industrial lists 16 wedge lock washer products, all from Nord-Lock, in metric and imperial sizes. For help comparing washer types, read our guide to types of washers.

Choosing a wedge lock washer

Wedge lock washers are chosen by bolt size, thread (metric or UNC) and material. Use the standard washer for most joints and the large O.D. version where you need a wider bearing area, for example over an oversized hole. Delta Protekt coated steel is the general choice, 316L stainless suits wet or corrosive conditions, and SMO 254 is listed for more demanding corrosive environments. Check the data sheet for the bolt class and joint each series is made for.

Fit the pair with the cam faces together under the bolt head or nut, and use a new pair when you reassemble. Compare with the other locking options: spring washers and tooth lock washers are general purpose anti-loosening aids, while Schnorr safety washers are a different spring-type washer.

Always check the data sheet. Confirm the series, size and material for your bolt and joint before you order, especially for safety critical joints.
