Bolt Torque & Preload Tension Calculator
Prevent thread stripping and bolt shear failure. Calculate tightening torque standards using standard VDI 2230 guidelines.
Fastening parameter design (Inputs)
* Mechanical engineering industry standard installation recommendations are 70% to 85% yield limit.
Bolt anti-loosening fastening mechanics report
Torque wrench setting target value
Bolt tension tensile force
Material tensile yield threshold
* Simulation description: The tension arrow represents the tension pre-tightening inside the bolt.. The blue/orange rod in the middle of the bolt changes with the slider to simulate real metal tensile elongation.. When entering the limit area of more than 90%, The member is drawn with a pronounced tapering (necking simulation) To warn of the risk of plastic damage.
