Tension Generating, Anti-Loosening Twisted Tooth Lockwashers
WCL is a leading supplier of the world’s largest and most diverse line of tapered, twisted tooth locking washers. Tooth lockwashers are the best anti-vibration, anti-loosening mechanical fastening devices available. These resilient washers stand up to high torques and heavy loads. Various styles of economical, standard tooth washers fit all conventional screw types and accommodate a wide range of hole configurations, including countersunk and oversized holes.
The twisted teeth on the tooth lockwasher compress as torque is applied to the fastening. A strong spring reaction is set up as the specially heat treated teeth seek to return to their fully twisted position. These unique washers make a significant contribution to the integrity of an assembly:
- Maintain essential tension.
- React instantly to any loosening influence, setting up a strut action that strongly opposes the loosening rotation of the fastener.
- Flexed teeth absorb shock and vibration.
- Resilient teeth absorb high torques and prevent slipping.
