Collection of 8 long German polygon wrenches in a cardboard box with dimensions 8, 9, 10, 12, 13, 14, 17, 19.

The wrenches are made of premium chromium-vanadium steel with increased density at points of higher pressure. Their special dimensions and construction enhance their exceptional strength and durability.

With a 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 screw head, instead of applying force directly on the edges.

The state-of-the-art design allows the wrenches to guarantee the transfer of force with precision and efficiency for tightening heads and nuts.
