Calibrated to an accuracy of +/ 4%, the TEKTON 3/8 in. Drive Click Torque Wrench lets you work with confidence, eliminating guessing and the common tendency to overtighten fasteners. Correctly tightening fasteners to a vehicle or equipment manufacturer's torque specifications ensures parts are properly secured without being damaged. Simple and easy to use, this wrench has a reversible ratcheting head that drives fasteners in both directions and measures torque in the clockwise direction. To measure torque, set the desired value on the handle scale (foot pounds or Newton meters) and begin tightening the fastener. When the preset torque value is reached, a reliable mechanical operation inside the handle produces a click you can hear and feel, alerting you to stop applying force. Built for consistent performance and years of dependable service, the mechanical design doesn't need batteries, and the allsteel construction has no plastic parts to break or wear out.
IMPORTANT: This wrench is shipped precalibrated and ready to use. To help maintain calibration, store at its lowest setting of 10 ft.lb./13.6 Nm when not in use. Be sure to read and understand the operator's manual, including all safety information, before first use.
