FAQs

Because the TN-tool is rotation based, can it do smaller sizes than what it is recommended for?

No, because for the tool to start counting the degrees of rotation, a certain torque must be met.

Does my TN wrench need to be calibrated?

No, Turn-of-Nut (TN) wrenches do not require calibration. TN tools are rotation tools and measure rotation mechanically. These tools either work or they do not. You can match mark to show they are functioning properly.

Are the same size sockets interchangeable between different tools?

Typically, the answer is no but there are exceptions. Contact a specialist if you have specific questions about your tool socket size.
