16x long German polygon wrenches (art 120/1) sizes 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8", 15/16", 1", 1.1/16", 1.1/8", 1.1/4".

The wrenches are made of premium chrome vanadium steel with higher density at points of highest pressure, which increases their excellent strength and durability.

With the special safety cut, the wrenches 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 head of the screw.

The state-of-the-art design enables Unior wrenches to guarantee the transfer of force with precision and efficiency.
