Features and applications
In order to pass the dead centre point and/or compensate for work piece tolerances when using hand operated toggle clamps,
an elastic clamping pad such as GN 708.1 can be used. GN 804 clamping bolts fitted with Belleville spring washers not only help
to overcome work piece tolerances but they also allow presetting of the required clamping force.
