Screw Tightening calculates screw ( bolt ) tightening values. DIN and imperial threads included.

The difference to other similar tools:

- Stiffness of the clamped (compressed) material considered
- Higher accuracy by using torque + turning angle instead of just torque
in tightening i.e. varying friction neglected
- Calculation of screw elongation
