Torque wrench 750NR
- The reliable and low-maintenance 750NR is always ready for use – ideal for manufacturing industry or tradespeople.
- When triggered, a strong haptic and acoustic “click” is generated (dual stop signal).
- Quick, effortless and precise adjustment and fixing of the target torque is carried out via a rotary knob at the end of the handle (1 turn = 5 N·m).
- The easy-to-read double scale (N·m/lb·ft) with additional fine scale prevents reading errors during torque adjustment.
- The SevenFiveZero lies perfectly in the hand and enables safe and comfortable working.

Technologies and features
QuickSelect
Lightning-fast target value setting: Unlock the adjustment knob, set the value, and lock the knob again.
Spring mechanism with the ‘click’
Our torque wrench uses a toggle lever as the switching mechanism. When the set torque is reached (click-type), the spring force is exceeded, causing the mechanism to slip and strike. This produces a clearly audible and perceptible ‘click’.
2-component handle
Our 2-component handle is non-slip and ergonomically designed. It is resistant to the most common oils, greases, fuels, brake fluids, and Skydrol.
DIN EN ISO 6789-2
Our torque wrenches and torque screwdrivers are professionally calibrated in accordance with DIN EN ISO 6789-2 and delivered with a corresponding calibration certificate. We also calibrate angle-controlled torque wrenches in accordance with VDI 2648-2. This ensures the accuracy and traceability of our tools.
