Hydraulic dynamometric wrenches are used when screwing or unscrewing hex nuts in hard-to-reach places/with limited space, requiring well controlled, repeated clamping turns, with high values. These wrenches allow for screwing/unscrewing of the nuts via double hexagonal cannular adapters fitted quickly on the cassette hexagon and by resting them against a neighbouring nut, with an anti-torque reaction arm. The wrenches do not distort the parts of the assembly. The bolt tensioner is used for the high precision pre-tensioning of threaded assemblies, as well as for removing these assemblies from places where the tensioning of the bolt body is not allowed, or it cannot be locked in the opposite direction of rotation. The advantage is the lack of a bolt tensioning tendency due to the symmetry of the support;
