Traditional systems such as Nylon Inserted nuts or spring washers do not work in many applications where joint movement and vibration occur. See our website and video explaining this and the benefits of Wedge Locking Washers.Our main products are TEC Series Wedge Locking washers to prevent nuts and bolts from coming loose across many applications and markets. but we will also look at other options if these are not suitable for the application.Challenge us with your next bolted joint.
