Material: Chrome vanadium, hardened in oil, zinc-plated. Manufactured according to ISO 2936 standards (metric only).

Long lifespan: The wrenches are made from premium chrome vanadium steel with greater density at the points of highest pressure. These dimensions and construction enhance their exceptional strength and durability.

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

Clean tool storage: The state-of-the-art design allows Unior wrenches to guarantee the precise and effective transfer of force for tightening heads and nuts.
