The Belleville washer shape achieves optimal friction locking while the helical gearing achieves the best possible form fit.
Advantages:
- Very good protection against pretension loss and loosening of screw connection
- No rupturing or splintering when tightening
Advice:
Do not use the washer in applications with direct exposure to the weather or in wet rooms with atmospheres containing chlorine gas.
