Wera ratcheting wrench Joker switch - US sizes 9/16"

With an open end on one side and a ratcheting box end on the other side. With identical sizes on both ends. 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. The box end head is angled at 15° from the handle. Comes with a switch for ratcheting direction and a very fine 80 tooth ratchet for a small 4.5° return angle. Size: 9/16". Overall length: 188mm.
