wera ratcheting wrench open box end joker metric sizes Size:18mm NGK Spark Plug KR9CI Fits: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. 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.
