EN 5910 Torque Limiting Knurled Knobs Technopolymer Plastic, Adjustable Torque, with Steel Tapped Insert

Product description

Torque limiting knurled knobs EN 5910 are used when the manually applied torque is to be limited. The torque limit can be set between 0.2 Nm and 1 Nm.

When turned clockwise, the torque mechanism of the knurled knob triggers an “over-engagement” as soon as the specified torque is reached. When tightening, this ensures that the maximum permissible torque is not exceeded. When turned counter-clockwise, the mechanism locks such that the torque necessary for release is transmitted properly.

Endurance tests have shown that the torque does not change even after up to 60,000 tightening cycles.

Adjustment of the Torque


To adjust the torque, the cover cap of the torque limiting knurled knob is removed to access the adjustment mechanism and to disengage the locking of the torque setting.
The torque is set with the hex socket head screw in the center of the knob. The graduated dial moves in the axial direction, increasing or decreasing the torque limit.
The set torque value is indicated on the graduated dial. Depending on the torque value, the slanted surfaces of the indicator window are level with the graduation marks of the graduated dial. After setting the torque, the cover cap has to be reattached. This locks the torque setting and protects the adjustment mechanism from unauthorized access.
