Irwin Bolt Extractors... love these!
I just found Irwin bolt extractors, the rosette-like sockets, and used them to get the bolts out of the connection between A4 output coupling and shaft coupling. These sockets fit around when other wrenches couldn't reach all sides of the bolt. The bolts didn't fit any standard or metric sockets since I cleaned off great amounts of rusty chunky corrosion. I did also spray PBlaster the day before. What a great tool. No one around here had seen them before and now I sound like a walking ad for 'em!
