So the little bolt with the nut that goes through the rear coaster brake arm I think the threads on the bolt are stripped. The little nut spins freely but won't come off. I'd rather not have to resort to using my Dremel on it or having to drill through it. I even tried holding a torch to it to try to heat up the nut but it didn't help. What else could I try to get that bolt out without having to Dremel or drill it? Any help will be appreciated.

Use a angle grinder with a cut-off wheel & cut it! (be a man) laff
Well he did do a manly thing and tried to use a torch on it. I don’t know how you thought it was gonna help if it’s already spinning free, @Rusty_Nail.

The manliest thing you can do with a map torch is light a cigarette with it, also it’s the only way without takin your eyes off the road windows down at 80mph… even manlier would be to light a very *short* roach…. I’ve never been that manly though…

The angle grinder, die grinder, Dremel tool, all would be alright. Just as Tony pointed out you would be best to immobilize the screw & nut from spinning before grinding, or just a hacksaw to cut the thing.

I have a chain nose vice grips which I would attach to something like this to stop it from turning. A bungee cord holding the vice grips in place and use my die grinder, that seem easy enough.

I had a front wheel axle that I used a regular vice grips to stop from turning while a cross threaded nut was preventing from taking the thing apart. Sometimes stuff happens, and things your about to fix, need additional things to fix in the process. Just get creative, but wear ear plugs, face mask, & face shield that covers neck area. Goggles are not going to prevent something like a cut off wheel fragment from ending up in the esophagus!

I use my die grinder with a separate speed control, this so I get a better control.

The bike itself could also be immobilized by using some cord or bungees. I used my old lead weight belt or heavy chain and bungees any time I use the center stand with one wheel off the bike. A stand that grabs and holds the frame still, I never got that fancy to buy the like, but improvised what I have works.

Lighting a Bunsen burner when the flints are all gone and no matches, heck we always had a large spool of 1 amp fuse wire. A cheater cord with face turned away with gas on, plug in wall socket and hear a pop. Fuse wire is vaporized and Bunsen burner is ready for glass blowing.

Today is my next opportunity to try to remove it(due to work). So I was thinking if the nut free spins, if i were to cut the nut off in segments(along the bolt not through it), then wouldn't I be able to just pull off the last part of the nut with some vice grips and not even have to cut the bolt? Then I could just remove the old bolt and replace with a fresh bolt and nut? I haven't had to cut nuts/bolts off many times so if I only get one shot to do it right I want to make sure it counts.
