Non-slip grip, with a rugged durable housing. High contrast, backlit LCD screen display.

Day in and day out, mechanics routinely tighten a variety of components to specific torque values. Despite their vast experience and attention to detail, even the best and most efficient mechanic can occasionally over-tighten or under-tighten a component, leading to vehicle damage or even catastrophic failure. This new digital torque wrench eliminates the possibility of human error with a series of lights and alarms that immediately alert the user to torque readings that are "over or under" entered values.
