MV = Pre-tensioning torque of the locknut [Nm]
FV = Required axial pretension force of the threaded connection [N]
B = Locknut-specific allowance [N], compensates face end relief due to the locking process
A = Constant [mm], includes the calculation factors for the respective thread width (catalogue value)
µA = Frictional coefficient for the end contact surface of the locknut Approximate value μA = 0.1 steel/steel
rA = Effective friction radius for the end contact face of the locknut [mm]
MD = Tightening torque per set screw [Nm]
FV = Required axial pretension force of the threaded connection [N]
A = Constant [mm], includes the Calculation factors for the respective thread width (catalogue value)
µD = Frictional coefficient for the end contact face of the set screw, Approximate value = 0.13
d6 = Dog point dia. of the set screw [mm] (catalogue value)
n = number of set screws
