RS PRO BZP Spring Steel Lock Washer


From the trusted RS PRO brand, this external tooth lock washer is ideal for added security in fixings and fastenings. They function in the same way as a standard washer, by distributing the load of a bolt against a surface material, but have a locking action that prevents turning of the fastener, meaning there is less chance of the fixing loosening over time or under repeated stress. As such they are commonly used wherever vibration is a factor.

Applications


External tooth lock washers, sometimes known as star washers, are a type of washer specifically designed to prevent loosening in larger fastener heads (as opposed to internal tooth types that are better for smaller fastener heads.)

They might typically be used in;

Domestic appliances such as washers and dryers
