US sizes. 4-piece set.

Incl. 4 wrenches with an open end on one side and a ratcheting box end on the other side,

with identical sizes on both ends. Packed in a robust

textile pouch with hook and loop on the rear side. Color

coded for size. When everything fails, it's time to play

your Joker.

- Open end.

The Joker has a non-angled 12-point beak, therefore it

requires just 30° of working space, otherwise it functions

just like a regular open end wrench. The dark metal

plate dual functions as a retainer, preventing the nut

to slip through the wrench beak or it holds the nut. 30°

further the metal retainer plate allows the nut to slide

through, or grip it since the metal plate is equipped with

a hardened ragged edge. The teeth of this edge will 'bite'

itself into a rounded-off nut, loosening it where others

do nothing but slip-off.

- Box end.

Comes with a very fine 80 tooth ratchet for a small

4.5° return angle. Ratcheting direction is indicated on both sides.
