ABSTRACT:
A screw-driver includes, disposed inside a driving handle, a torque limiter having a torsion spring in which one end of a helical friction band carries a ring connected by axial splines to a stem of the tool while the corresponding end of the torsion spring is fixed to a ring connected to the stem by a helical spline. An adjusting sleeve solely movable in rotation is screwed on the stem and, when it rotates, causes an axial displacement of the stem and modifies the relative angular setting of the two end rings, i.e. the torsion of the spring and consequently the value of the sliding torque.
