separate multiple mail address using a comma.

* mandatory fields

Details

Application Areas:

Securing screwed connections that are exposed to dynamic loads such as oscillations or vibrations

The washers can also be used in countersunk holes and with cylinder head screws

Advantages:

  • Reliable connections
    • High vibration resistance due to positive locking of the helical teeth
    • The closed ring shape achieves high preload force (good frictional connection)
    • No bending moments, as the force application is concentric
    • No chip formation during tightening due to sliding surfaces
    • No bursting open when tightening

Processing information

For screws up to strength class 8.8

Advice

Blackened
The disc spring shape achieves an optimum frictional connection with the highest form closure at the same time due to helical gearing
Type S = with standard contact surface
