Washers

Wedge-Lock Washers

Wedge-lock washers utilize geometry-based tension via interlocking cams and radial teeth to secure bolted joints against severe vibration and dynamic loads. As the cam angle exceeds the thread pitch, any rotational loosening forces the washers to expand axially, effectively increasing clamping tension. Manufactured from high-strength steel or alloys, they are critical for structural steel, robotics, and heavy transport assemblies requiring guaranteed preload maintenance.
