I have a Ryobi RY3716 chainsaw. I lost a bar flange nut and replaced it with a non-Ryobi part (something like this one).
The new nuts didn't fit exactly, but I forced them on, causing damage. Now I can't remove them without removing the bolt they screw onto. I want to replace the nuts and the bolt with Ryobi parts, but I can't figure out what the bolts are called.
The parts manual is here. The flange nut is 678339003.
