What is a torque wrench ?
Used in car garages or in industry, a torque wrench is used to check and adjust the tightening torque of bolts, screws and nuts.
A torque wrench is a precision tool which guarantees reliable and quality tightening. Its use is essential to avoid any deterioration or breakage on the various clamping parts.
The tightening torque is expressed in Newton Meter (N.M). The N.M represents the moment of a force of 1 newton with a lever arm of 1 meter.
Depending on the type of application and the materials, it is advisable to tighten to the right torque, referring to the instruction manual.
Here are some steps to help you make your choice:
- Torque from 1 to 20 N.m: for tightening on fragile parts (carbon bike, small aluminum parts, etc.)
- Torque from 20 to 150 N.m: for cars, motorcycles (cylinder heads, damper pulleys, rims, etc.)
- More than 150 N.m: utility or agricultural use, for very high tightening forces.
