The keys are made of Premium chrome vanadium steel with greater density at points of higher pressure, which enhances their exceptional strength and durability.

With the special safety cut, the keys prevent damage to the corners and edges of screws and nuts by distributing the force evenly across the surface away from the outer lines of the nut or the screw head.

The state-of-the-art design allows Unior keys to guarantee the transfer of force with precision and efficiency for screwing in heads and nuts.
