Vargal® nuts are self-locking nuts with an external elastic spring which determines a radial deformation.
Vargal® self-locking nuts have been succesfully used through the years in all security applications requiring:
- excellent resistance to vibrations
- high temperature applications
- limited friction coefficient dispersion generated by the prevailing device
- the possibility to reuse the nut without any decreasing of the removal prevailing torque
The nut prevailing torque is guaranteed by the action of the stainless steel spring, pressing on the collar with radial cuts.
