Fix It Sticks' Small Torque Limiters prevent over-tightening of fasteners. When you reach the correct Nm of torque, you'll hear an audible "click" and the limiter will spin to prevent further torque from being applied. Each limiter accepts any standard 1/4" bit, fits into any standard 1/4" driver, including Fix It Sticks Tools or our T-Way Wrench, and tightens precisely (+/- 6% accuracy). Each retains its accuracy for up to 20,000 cycles.
