The keys are made of Premium vanadium chrome steel with a higher density at the points of higher pressure, and such dimensions and construction only increase their excellent power and durability.
With their special safety cutting, the keys prevent the destruction of the corners and edges of screws and nuts by distributing the force evenly to the surface away from the outer lines of the nut or screw head instead of directly to the edges.
The cutting-edge design makes the Unior keys guarantee an accurate and efficient transfer of force to the heads and nutes of the screws.
