With special safety cuts, the keys prevent damage to the corners and edges of screws and nuts by distributing the force evenly over the surface away from the outer lines of the nut or screw head, rather than applying force directly onto the edges.
The state-of-the-art design enables Unior keys to guarantee the transfer of force accurately and efficiently, for screwing heads and nuts.
