Torque Wrench Calculator

Calculate required torque for bolt tightening using the formula T = K × D × F. Supports metric and imperial units with common nut factor references for different bolt conditions.

How to Use Torque Wrench Calculator

Enter the bolt diameter, desired clamp force, and nut factor (K). The calculator computes the required torque in N·m, ft·lb, and in·lb using the standard torque formula.

Step-by-Step Instructions

  1. Enter bolt diameter and select unit (mm or inches)
  2. Enter desired clamp force and select unit (N or lbf)
  3. Set the nut factor K for your bolt condition
  4. Click Calculate and view torque in multiple units
