For tightening with particularly high precision (assembly of engine components, critical building structures), use arrow keys for quick assembly with the required tightening torque (tightening anchor bolts, tightening bolts during tire mounting), use limit type keys
Do not exceed the maximum torque for which the key is designed, this will damage its mechanism.
Even with some experience, you need to use a wrench to tighten with a certain torque.
Limit type torque wrenches should be stored with the value set to zero.
Take care of the key body from deformation and damage - this can lead to jamming of the internal mechanism and inaccurate readings.
