Klein Tools 57005 3/8" Ratchet Torque Wrench
The Klein Tools 57005 is a precision 3/8-inch drive ratcheting torque wrench designed to apply exact torque values ranging from 30 to 250 inch-pounds (3.39 to 28.25 Nm). Engineered for professional industrial applications, this tool features a steel case enclosing a precision power spring, a torque signaling mechanism, and a ratchet drive tang. A quick-release lever permits micro-adjustments for increased accuracy, while the stainless-steel handle provides an adjustable grip with a built-in locking device.
Each unit includes a N.I.S.T. traceable calibration certificate confirming compliance with the ASME standard of ±4% accuracy. The wrench limits torque in the right-hand direction only, but can be safely used to loosen fasteners provided the required force does not exceed the tool's rated capacity.
