GN 3663 Torque Limiting Knurled Knob Screws Aluminum, with Steel Threaded Stud


GN 3663 Aluminum Torque Limiting Knurled Screw, with Steel Threaded Stud

Product description


GN 3663 torque limiting knobs 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 tightening, this insures that maximum permissible torque is not exceeded. When turned counter-clockwise, loosening the knob mechanism, the mechanical system locks so that the torque is not limited. Torque necessary for release will always be transmitted properly.

After removal of cover and loosening of the countersunk screw, insert with threaded stud can be dismantled.
