The figures in parentheses show metric size and the fractions show size in inches.

The inch size screws are Unify screw in ISO standards. Unify screw is specified as the screw with 60 degree thread both in UNF and UNC specification.

About Torque

What is torque?

  • Torque is the measure of a force’s tendency to produce rotation or torsion.
  • The measure of Torque is now used for screw fastening using a tools like hexagon wrenches.
    • Torque is defined as “Force” × “Lever-arm distance”.

For instance, when holding and applying force to a hexagon wrench inserted in a hexagon socket head bolt at 0.2m away from the center of the bolt with force of 10N, the tightening force is;

from the Formula : FXL=T (F: Force N, L: Lever-arm distance m, T: Torque N・m)

10N × 0.2m = 2.0 N・m It is also deduced from the Formula that F (force applied) necessary to obtain the tightening torque of 2.0 N・m with L:0.4m is 5N.

  • ISO and JIS stipulate a guaranteed torque value for each size of hexagon wrenches within which they will not be broken, twisted, distorted in a hexagon shape or bent to the extent that they will become unusable. They also demonstrate the test method with a torque wrench.
  • ISO and JIS specify that hexagonal wrenches shall not be broken or cause any irregularities such as twisting, deformation in the hexagon shape, or bending when used within proof torque values (ISO 2934,JIS B 41648).

-JIS specification shows proof torque values for each size as well as the test method using a torque wrench.
