What this tool does

This tool estimates torque-wrench correction when an extension changes the effective lever length.

How to use it

Enter the values from the catalogue, data sheet, supplier quote or site measurement. Review the assumptions before sharing or printing the result.

Calculation method

Required wrench setting = desired fastener torque x wrench length / effective total length.

Assumptions and limitations

Torque is an indirect control method. Use calibrated tools, correct geometry and manufacturer instructions for safety-critical work.
