Case description:
Select: Standard US units metric units
Only 0-9, / and . allowed in the following boxes.   
Nominal diameter = D inchmm
Pitch threads / inch mm / thread
Torque = T in-lbs
N m
Nut Factor = k, in:
Bolt force = T / (k D)
nondimensional factor
Bolt Torque Factor = q = ratio of torque in the stressed bolt cross-section to the torque applied to the bolt nondimensional factor
