Product Description

GN3663 Torque Limiting Knob Screws

Torque knurled knob screws, GN 3663, are used when manually applied torque is to be limited.

When turned clockwise, the torque mechanical system of the knurled knob triggers an over-engagement as soon as the specified torque is reached. When turning anti-clockwise, the mechanical system locks so that the torque is not limited. When tightening, this will ensure that the maximum permissible torque is not exceeded. On the other hand, the torque necessary for releasing will always be transferred easily and reliably.

After removing the cover and loosening the countersunk screw, the thread or bore insert can be dismantled.
