Tool for designing the optimum tightening torque in a bolted joint with PowerTorque LF KOTE 450, LF 450 R or LF Booster.
Need help with the calculation?
Enter input values such as bolt diameter, friction coefficients and other necessary parameters.
The calculator will calculate the optimum tightening torque that provides the necessary bolt tension in the mounting condition.
To verify the designed tightening torque, the load on the coupling in the assembly state is displayed.
The calculation uses the friction parameters in the bolted joint determined by experimental measurement according to EN ISO 16047.
Including limit deviations to account for the variance of measured friction coefficients.
In terms of shank stress during assembly.
