Frequently Asked Questions
What is a torque wrench used for?
A torque wrench is a precision tool used to apply a specific amount of torque to a fastener (such as a nut or bolt). This prevents over-tightening or under-tightening, ensuring mechanical safety and preventing component damage.
How often should a torque wrench be calibrated?
To maintain accuracy, it is highly recommended to calibrate your torque wrench once a year, or after every 5,000 to 10,000 cycles, depending on whichever comes first or based on your specific industry standards.
Can I use a torque wrench to loosen tight bolts?
No, you should never use a torque wrench to loosen bolts. Doing so can overload the wrench, exceed its maximum torque capacity, and damage its internal calibration mechanism.
How should I store my torque wrench after use?
For click-type torque wrenches, always wind the setting back down to its lowest marked scale value before storing. This relieves tension on the internal spring, preserving the tool's accuracy over time.
What indicates that a click-type torque wrench has reached its target torque?
When the target torque is reached, you will feel and hear a distinct "click" or break in the wrench handle. Once you feel or hear this signal, immediately stop pulling to avoid over-tightening.
