Torque Wrench Extension Calc app for iPhone and iPad
When you put an extension on a torque wrench, the torque applied to the fastener increases.
Use the Norbar Torque Wrench Extension Calculator app to find what value you should set into the wrench to achieve the required fastener torque.
The app comes in four language options, English, French, German & Spanish. The language option is only available on the initial loading of the app.
