Wera ratcheting wrench set Joker open/ box end - Metric, Black, 10 mm

Metric. 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.
