Wedge Lock Washers

A wedge lock washer fastener, also known as a serrated lock washer or toothed lock washer, is a type of lock washer designed to prevent nuts and bolts from loosening due to vibration or other external forces. It has a unique shape characterized by its serrated or toothed edges, which resemble the shape of a saw blade or a series of waves. Here's how a wedge lock washer works: Increased Friction: When a wedge lock washer is placed under the nut or bolt head and the fastener is tightened, the serrated edges of the washer bite into both the fastener and the material being fastened. This creates increased friction and resistance to rotation. Prevents Loosening: The serrations effectively "lock" the fastener in place, making it less likely to come loose over time, even in applications with significant vibration or movement. Wedge lock washers are commonly used in various industries, including manufacturing, construction, automotive, and machinery, where secure and stable fastening is crucial. They are available in different sizes and materials to accommodate various applications and are known for their reliability in preventing fastener loosening.
