With the special safety cut, the keys prevent damage to the corners and edges of the screws and nut, distributing the force evenly onto the surface away from the outer lines of the nut or screw head, instead of exerting force directly onto the edges.
The state-of-the-art design enables the Unior keys to guarantee the transfer of power with precision and efficiency, for screwing heads and collars.
