What does NM mean on torque wrench?
Newton metres
Torque is measured in Newton metres (Nm) or you might see the imperial measurement of lb-ft (pounds-feet). If you want to calculate the conversion for yourself, 1 Nm is equivalent to 0.738 lb/ft.
What is the best range for a torque wrench?

How much torque does a torque wrench need?
Moderate duty automotive fasteners require between 50 and 250 ft. lbs. While fewer fasteners fall into this range than light duty fasteners, those which do are critical applications.
How do you read a Nm on a torque wrench?
Look at the meter at the bottom of the torque wrench. The numbers represent the amount of torque in either foot-pounds (ft. -lbs.) or Newton meters (Nm). Wherever the arrow is pointed designates the amount of torque that you’re applying to a lug or nut. In the stationary position, the wrench should read 0.
What is Nm torque measurement?
One newton-metre is the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long. One newton-metre is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long.

How do I know if my torque wrench is accurate?
How do I know if my torque wrench is calibrated correctly? The only way to know if your wrench is accurate is to have it calibrated by a qualified calibration lab or do it yourself as was described above with a vise and weights. Proper calibration, however, requires certified weights.
How is the torque on a torque wrench measured?
A main pointer on the dial shows torque as it’s being applied and a memory pointer indicates the maximum torque reached. Trust the precision of your measurements— these wrenches are accurate to ±2%. Measure with an accuracy of ±7%.
When do torque limiting wrenches stop turning fasteners?
These wrenches slip to disengage and stop turning the fastener when the set torque is reached, preventing overtightening. Turn sockets from above when there’s not room to swing a standard wrench handle. When the set torque is reached, these wrenches signal with an audible click and an impulse in the grip.
What kind of copper is a torque wrench made of?
No need to pull the socket off the tool— push a button to release. Made of beryllium copper, these wrenches satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.
