Torque
Screw Torque
Torque T is the force that turns the screw in the direction of rotation when it is turned and tightened.
When tightening the screw, it is managed by the tightening torque.
If the tightening torque is too small, the screw will loosen, and if the tightening torque is too large, the screw will break.
Tightening torque T = F1 × L [N・m]
F1: Pushing force
L: Distance from the center of rotation to the point of applying force
Maximum torque load - references.

Unit Legend:
- in: Nominal Thread Size (inches)
- mm: Nominal Thread Size (mm)
- Newton (N): Axial Force (Metric SI unit)
- N.m: Tightening Torque (Newton-meter, Metric SI unit)
- lbf: Axial Force (Imperial unit, pound-force)
- lbf.ft: Tightening Torque (pound-foot, Imperial unit)
The unit of torque used to be kgf·m (gravity system of units), but the "New Metrology Law" came into effect in 1993 made it mandatory to move to SI units (ISO international standards), and now N (Newton) is used as the unit of force and N.m (Newton-meter) as the unit of torque.
