Lock washer for Terex BT4792

The W07-312X000-20 lock washer is a medium split-type fastener component used within the boom rest assembly of Terex machinery. It features a nominal diameter of 0.3125 inches, corresponding to a 5/16-inch size, and is manufactured from zinc-coated steel.

This component is specifically utilized in the boom rest assembly of the Terex BT4792 model. It is designed to be installed on bolted connections to maintain tension and prevent loosening caused by operational vibrations or dynamic loading.

Lock washers of this type function by providing a spring force that exerts pressure on the fastener assembly, effectively locking the bolt or nut in place. By maintaining consistent clamping force, they help preserve the structural integrity of the joint and ensure that critical connections remain secure during the operation of the crane.
