Others :
1. The above torque rating have been determined to 70% or so of the limit value for
bolt elasticity.
2. Tension is calculated by multiplying tensile strength by cross section of thread.
3. Special screws should be tightened to 85% or so of the standard value.
For example, a screw coated with MoS
2
should be tightened to 60% or so of the
standard value.
