Result Interpretation

Derive target torque using K-factor model computes tightening_torque in N·m using the defined engineering formula and the input values provided. tightening_torque is expressed in N·m. No universal acceptance threshold is defined by this calculator.

Worked Example

M8_8.8_normal

Given:

  • bolt_grade = 8.8
  • nominal_diameter = 8
  • friction_condition = normal

Expected Result:

  • tightening_torque = 28.1088

Engineering Interpretation:

Under the given input conditions, the calculated result is: tightening_torque = 28.1088 N·m.

The values shown here come from a persisted test case that has not been deterministically revalidated. Enter the inputs and click Calculate for the authoritative engine-computed result.

Formula / Method

tightening_torque = k_factor * preload_force * (nominal_diameter / 1000)
