Torque wrenches of new concept, designed and manufactured to exceed performances required by EN ISO 6789-1:2017.
The wrench works with a “variable arm clicker mechanism”.
Torque variations are obtained not by screwing or unscrewing a spring (the critical component in a standard click type wrench) but by a variation of levers positions.
The spring inside works always in the same condition, independently of torque selected.
This innovative system guarantees endurance and stability.
