Klein Tools 57000 3/8'' Ratchet Torque Wrench, 10-100 Ft-Lb

Klein Tools 57000 3/8" Ratchet Torque Wrench (10–100 Ft-Lb)

The Klein Tools 57000 Ratchet Torque Wrench is a professional-grade fastening tool designed to apply precise torque values from 10 to 100 ft-lb (13.56 to 135.58 Nm). Featuring a durable steel case containing a precision power spring and torque signaling mechanism, it alerts the user when the desired torque is reached. The micro-adjustable quick-release lever enables highly accurate torque settings, while the stainless-steel handle offers an adjustable hand grip with a built-in locking device to prevent accidental changes during use.

This 3/8-inch drive wrench includes a N.I.S.T. traceable calibration certificate verifying accuracy to the ASME standard of ±4%. It limits torque exclusively in the right-hand (clockwise) direction, though its ratchet mechanism allows it to loosen fasteners provided the tool's maximum rated capacity is not exceeded. Both the steel case and handle grip are stamped with high-visibility calibration markings for quick reference in the field.
