FAQ

Frequently Asked Questions

Are the original calculator functions preserved?

Yes. The tool pages keep the standard thread library, custom metric and imperial thread inputs, tolerance class selector, torque-preload model, material grades, shear checks, engagement length output, chart, PDF export, PNG export, and print button.

Can torque results be used directly?

Use torque values as engineering references. Friction, lubrication, plating, washer condition, and assembly method can cause large preload variation.

How do I report an issue?

Email support@threadcalculator.online with the page, thread size, material grade, inputs, and expected result.
