Fastener Pro

Bolts/Fastener and Gasket Stress Analysis

Determine a safe and reliable fastener torque for your application. By selecting your bolt material spec, nut material spec, and set material specs from our comprehensive material database we will evaluate all possible failure modes of the bolt, nut, set material, and joint materials and provide a details stress analysis as well as the recommended torque. Additional features include determination of preload from torque, torque from preload, load analysis, and equivalent angle to turn fastener to achieve desired results.

Disclaimer: Bolt torque and preload values are estimates only. Actual requirements depend on material, lubrication, standards, and installation conditions. Verify all values using official engineering documentation and calibrated tools. Developer assumes no liability for use of this information.
