Frequently Asked Questions - Click-Torque C 3 Wera
How do I set the torque on the Click-Torque C 3?
Rotate the knurled barrel to align the desired torque value with the reference mark on the handle. The scale is in Nm with 0.1 Nm increments. Always set the torque from a lower value upward to avoid overshooting.
Is the Click-Torque C 3 suitable for left-handed threads?
Yes, the tool works in both clockwise and counterclockwise directions. However, the torque accuracy is only guaranteed for clockwise tightening. For left-handed threads, use the same setting but note that the click mechanism may feel different.
How do I know when the set torque is reached?
When the preset torque value is reached, you will hear a distinct click sound and feel a slight release in the handle. Stop applying force immediately to avoid overtightening.
Does the Click-Torque C 3 require calibration?
It comes factory calibrated. Wera recommends recalibration at least once a year or after 5,000 cycles, whichever comes first. Calibration should be performed by an authorized service center.
Can I use this torque screwdriver as a regular screwdriver?
It is designed specifically for torque-sensitive applications. Using it as a regular screwdriver may wear out the internal mechanism. On tightening, once the click occurs, do not continue turning. On loosening, it works like a normal screwdriver.
What is the correct way to store the Click-Torque C 3?
Always store the torque screwdriver with the torque set to its lowest value (1.0 Nm). This relieves tension on the internal spring. Keep it in a dry environment, preferably in its original case or a soft pouch.
What drive size does the Click-Torque C 3 accept?
The tool has a 1/4" hex drive and accepts standard hex bits. Ensure bits are securely inserted before use.
Is the torque setting adjustable without tools?
Yes, the knurled barrel allows tool-free adjustment. Simply turn the barrel to the desired torque value.
What should I do if the tool does not click at the set torque?
Do not use the tool. The internal mechanism may need recalibration or repair. Contact Wera customer service or an authorized service center immediately.
Can I use extension bars with this torque screwdriver?
Wera advises against using extensions as they can affect torque accuracy. If necessary, use only Wera-approved extensions and reduce the set torque by an appropriate factor; consult the manual for details.
