A 4 mm hex driver that stops at 5 Nm every time. The value is fixed and tamper-proof, and the pistol-grip Kraftform handle gives plenty of purchase.

Highlights

  • 4 mm hex blade, fixed at 5.0 Nm (3.7 ft lb)
  • Tamper-proof, non-adjustable setting
  • Distinct audible and perceptible signal at the preset value
  • Unlimited torque for loosening seized screws
  • Multi-component Kraftform pistol handle

Fixed torque

The torque is set at the factory and can't be changed. When 5 Nm is reached it signals clearly and won't go further; turn it the other way and there's no limit, so it undoes seized screws too.

Compatibility & fit

For 4 mm hex socket screws specified at 5 Nm. Only use it where your component maker specifies 5 Nm, as it can't be set to any other value.

Wera warrants its torque tools against defects in materials and workmanship. Normal wear, misuse, modification and damage from abuse are not covered. Like any torque tool, it should be checked and recalibrated periodically; Wera Tools Australia names Zenith Sales and Calibration Pty Ltd as its approved Australian repair and calibration centre for Wera torque tools. This sits alongside your rights under the Australian Consumer Law.

For warranty support, return the product to Tune Cycles and we'll manage the claim with Wera's Australian distributor.
