The torque limit can be set between 0.2 Nm and 1 Nm. 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 will ensure that the maximum permissible torque is not exceeded. When turned counterclockwise, the mechanism locks such that the torque necessary for releasing is transferred. Endurance tests have shown that the torque does not change even after up to 60,000 tightening cycles. see also... • Torque Limiting Knurled Knobs / Knob Screws GN 3663 → Page 652 • Torque Limiting Triangular Knobs GN 5344 → Page 656 • Torque Limiting Wing Nuts / Wing Screws GN 5320 → Page 657 Information 1 d 1 2 d 3 3 Length l 4 max. torque 5 Color How to order (Threaded stud) 1 2 3 4 5 GN5910-47-M8-40-1-SW • Plastic Technopolymer (Polyamide PA) - - Glass fiber reinforced - - Temperature resistant up to 80 °C - - Black, matte finish SW • Threaded stud Steel, blackened • Bushing Steel, blackened • Color of the cover cap Gray, RAL 7035 • Plastic Characteristics → Page 2158 • RoHS Specification 5 1 d 1 2 d 2 4 max. torque 5 Color How to order (Bushing) 1 2 4 5 GN5910-47-M6-1-SW Original design MZD-A/-p GN 5910 Torque Limiting Knurled Knobs / Knob Screws with Adjustable Torque
