For tightening with particularly high precision (assembly of engine units, important building structures), use pointer wrenches; for quick assembly with the required tightening torque (tightening anchor bolts, tightening bolts during tire fitting), use limit type wrenches
Never exceed the maximum torque for which the wrench is designed, this will damage its mechanism.
Even with some experience, you need to use a wrench for tightening with a specific torque.
Torque wrenches of the limit type should be stored with the zero value set.
Protect the wrench body from deformation and damage - this can lead to jamming of the internal mechanism and inaccurate readings.
