GN 804 Clamping Bolt with Adjustable Spring Loaded Thrust Pad

In order to pass the the dead centre point and / or compensate for work piece tolerances when using hand operated toggle clamps, an elastic clamping pad such as GN708 can be used.

Clamping bolts GN804 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 pressure pad is movable.
