Inch Bolt Torque Specs: Estimated with clamp load as 75% of proof load as specified in SAE J429 and ASME 574.
Metric Bolt Torque Specs: Estimated with clamp load as 75% of proof load as specified in ISO 898-1.
Torque Conversion:
Torque Units Conversion CalculatorNew calculator to convert torque specs from bolt torque chart specs.
    Easy-to-use calculator to convert torque units when the specified unit doesn't match the unit of the available torque wrench or torque screwdriver.

Torque Conversion Table
    Chart of multiply-by values to convert common inch and metric torque units, plus torque unit cross reference.
Torque Wrench:
Torque Wrench Adapter Calculator
    Calculates the proper torque wrench setting when using an offset adapter. The torque wrench setting should be calculated when using an offset adapter because the offset adds or subtracts from the length of the torque wrench to the fastener.

Torque Wrench Tips
    Proper torque wrench handling and use. Since a torque wrench is a precision instrument, it's important to use it properly and handle it carefully.
Misc. Torque:
Thread Engagement
    Article about the thread engagement between a bolt and a cut tapped hole. Refers to three conditions, percentage, length, and minimum length, of thread engagement. An understanding of those three conditions is relative to the Torque Specs section to help prevent stripping out the threads in the tapped hole when appling torque to the bolt.
