Frequently Asked Questions About the Wera Click-Torque C 3 Adjustable Torque Wrench
What is the torque range of the Click-Torque C 3?
The Click-Torque C 3 covers 40-200Nm (approximately 30-146 lbf-ft) on a 1/2″ square drive. It’s a mid-to-heavy range adjustable torque wrench suited for structural fasteners, large battery terminals, conduit connections, and equipment mounting hardware.
How accurate is the Click-Torque C 3?
It’s calibrated to ±3% accuracy in compliance with DIN EN ISO 6789-1:2017-07, the internationally recognized standard for hand torque tools. This level of precision is appropriate for professional installation work where torque values are specified by equipment manufacturers and may be subject to inspection.
Can it apply torque in both directions?
Yes. The Click-Torque C 3 uses a captive square head insert that reverses the ratchet direction smoothly between clockwise and counterclockwise. This means it works with both left-handed threads and right-handed threads.
How do I know when I reach the set torque?
The release mechanism produces both an audible and physical click when it reaches the preset torque. This dual feedback works even in noisy environments.
Is this a suitable electrical torque wrench for solar battery terminal work?
Yes, with an important caveat. The Click-Torque C 3 is not VDE-rated or insulated, so it should only be used on de-energized or safely isolated systems. For battery terminal torquing, ensure the battery is disconnected from load and charge sources before maintenance. Always verify the torque spec prior to tightening the fastener.
What drive size does it use?
The Click-Torque C 3 uses a 1/2″ square drive with an integrated socket locking feature, compatible with the broad range of 1/2″ drive sockets available in most professional and home toolkits.
