JCB Mechanical Torque Wrench - 3/8 inch - 5-25 Nm

No. Torque wrenches are precision measuring tools and should never be used as a standard ratchet to break loose tight or rusted bolts.

The tool comes with a calibration certificate; however, for professional use, it is recommended to have it recalibrated annually or every 5,000 cycles.

Yes, this wrench supports bidirectional operation, allowing for torque-controlled tightening in both clockwise and counter-clockwise directions.

If the wrench is dropped, it may have lost its calibration accuracy. It should be checked by a professional calibration service before being used on critical components.

Always dial the wrench back to its lowest setting (5 Nm) before placing it in the provided storage case to preserve the internal spring mechanism.

Ensure you are applying slow, smooth pressure when nearing the target torque. Applying force too quickly can bypass the click signal.

Verify that the locking ring at the base of the handle is fully in the 'unlocked' position before attempting to rotate the grip.
