Torsion bar 135Nm 1/2''

Torsion bars are suitable for tightening nuts with an impact socket wrench. Once the recommended torque is reached, the key head stops and the torque head returns after each impact. You can achieve a finished result by tightening with a torque wrench to the required torque. The maximum torque for each bar can be identified by the color-coded ring:
- Drive: 1/2" socket
- Surface finish: Black phosphate coating
- Hardness: 40–48 HRC
