The Fix It Sticks Bit Driver Torque Limiters prevent over-tightening of fasters. When the proper inch-pounds is reached, an audible "click" is heard. The Limiter "spins" preventing further torque from being applied. They accept any standard 1/4" bit, fit any 1/4" driver, and are +/- 6% accurate.
Integrates perfectly with Fix It Sticks Replaceable Edition and T-Way Wrench for field / travel use.
