Properties and application:
- In order to pass the dead centre point and / or compensate for work piece tolerances when using hand operated toggle clamps, an elastic thrust pad such as GN 708.1 can be used
- Toggle clamp spindle assemblies GN 804 fitted with Belleville spring washers do not only help to overcome workpiece tolerances, but they also allow presetting of the required clamping force
- This adjustment can be made with the hexagon nut (A/F)
- The setting nut stroke is the distance by which the Belleville washers can be preloaded as shown on the above graph to give the required clamping force
- Furthermore the thrust pad is movable
- Hexagon nuts are included
