How to calculate the torque of torque wrench

Torque wrench is calculated by nm, nm is a physical definition, the unit of torque is the proct of the unit of force and the unit of distance, that is Newton * m, abbreviated as nm

definition:

unit of moment Moment: proct of force and arm of force)

formula:

1 Newton × 1 m = 1 nm Newton: vector, meter: scalar)

nm to KGF:

1n * m (n * m) = 0.101972 KGF * m (KGF * m)

1kg force * m (KGF * m) = 9.80665n * m (n * m)

you just need to convert the meter into kilogram

extended data:

the main feature of torque wrench is that the torque can be set and adjustable

Application of torque wrench:

torque wrench is used to fasten bolts. High strength bolts can be divided into torsional shear type and large hexagon type. National standard torsional shear type high strength bolts are M16, M20, M22 and M24, and now there are non national standard M27 and M30; The national standard large hexagon high strength bolts are M16, M20, M22, M24, M27, M30, etc

generally, the high-strength bolts should be tightened first and then finally, and each step needs to have strict torque requirements. Constant torque wrench must be used for initial tightening and final tightening of large hexagon high strength bolt

use:

the torque wrench can be used for both initial tightening and final tightening. Its use is to adjust the torque first, and then tighten the bolts

characteristics of constant torque electric wrench:

easy to operate, time-saving and labor-saving, torque adjustable

Torque wrench 150n / M means the maximum torque is 15N * M< br />
