The wrenches are made of premium chrome vanadium steel with higher density at the points of greatest pressure, featuring dimensions and construction that enhance their strength and durability.

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

The state-of-the-art design enables Unior wrenches to guarantee the precise and efficient transfer of force for tightening heads and nuts.
