For tightening with particularly high precision (assembly of engine components, critical building structures), use arrow wrenches for quick assembly with the required tightening torque (tightening anchor bolts, tightening bolts when mounting tires), use limit wrenches

Never exceed the maximum torque for which the key is designed, this will damage its mechanism.

Torque wrench

Even with some experience, you need to use a wrench to tighten with a certain torque.

Torque wrenches of limit type should be stored with a set value of zero.

Protect the key body from deformation and damage - this can lead to wedging of the internal mechanism and inaccurate readings.
