Simple guide to insert and shell tools
Prevent torque errors – adjusting the extension length
When you are working with insert tools, the extension length can change – which also alters the effective force loading point of the torque wrench. The problem: The wrench clicks even though the torque actually applied does not match the specified value. A small deviation can have major consequences. The solution: With our extension length calculator, you can work out the correct setting value (WK) quickly and reliably. You can therefore ensure that your torque wrench works precisely in conjunction with insert and shell tools. 👉 Tip: Our video demonstrates why the extension length is so crucial.
