Help, I was an eager beaver and used my impact driver to install drip rails. I stripped the A574 bolt that is supposed to be hand tightened into the T nuts. Who has a solution for extraction?
Not sure what the A574 bolt is, can you show a picture?
Typically, when I have stripped bolts (at my old job it was one of the many tasks others made for me) I would have to drill them out. Either drill the head off and push it through or drill the body out and peel out the threads with a pick.
You could also try to glue something in the bolt head with super glue and turn that?? Never worked for me, but my stuff was industrial.
Good luck
Hammer a slightly larger torx bit into the stripped hex
Cut a slot in the bolt head with a dremel and unscrew with a flat head
Use vice grips to grip the outer edge of the bolt and unscrew it

Once you get them out the DripRails should be mounted in the upper track. They will catch too much wind in the lower track and will crack over time.

OK, I see.
Likely the A574 is a manufacturer stamp for the bolt part number or for the coating, it’s not really a bolt description. The bolt is a 1/4"-20 socket head cap screw 3/8" or 1/2" long (hard for me to tell in the picture). A very standard size.
It may be a big contributor to the bolt stripping is the quality of the hex wrench you were using. Most brands are pretty soft, and the corners start rounding. I highly recommend getting a high-quality set such as Bondhus, you can find some reasonably priced sets online.
