Wright Tool 4478 1/2 in. Drive Micro-Adjustable Click-Type Torque Wrench, 50–250 ft-lb (Each)

The Wright Tool 4478 is a professional-grade, micro-adjustable click-type torque wrench designed for precise industrial fastening applications. Its exposed dual scale provides readings in foot-pounds and newton-meters, while a distinct break and audible click signal when the selected torque is reached.

The 24-tooth ratcheting head features a push-button socket release. A spring-loaded pull-down lock ring prevents the selected setting from being accidentally changed. The wrench is manufactured from alloy tool steel and includes a fitted storage case and serialized calibration certificate traceable to NIST.
