💡 How do locking washers prevent fastener failure on vibrating equipment?
These anti vibration plates use mechanical wedging to maintain bolt tension under heavy loads.
- The tapered cam action forces radial expansion against the fastener thread roots
- Split outer segments grip surfaces firmly to block lateral shear movements during travel
- Oxidation resistant copper alloys keep friction coefficients stable across changing weather conditions
