Torque Limiting Knobs / GN 3663

Promotional pricing
Volume Discount

Torque limiting knobs GN 3663 are used when the 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 such 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 reliably.
After removing the cover and loosening the countersunk screw, the thread or bore insert can be dismantled.
