I was working on my brakes and took off a brake mount to work more easily and I screwed the bolt back in its place and it stripped. What are your guys advices on stripped bolts? This is a difficult case as it is a round head with a rounded allen inside, and it also is very small, 2.5 mm. Are the bmx gods telling me to run no brakes? Perhaps. Any advice for unscrewing the bolt? Photo

Use a dremel to make a spit in it and use a flathead screw driver to remove it and then buy a new bolt...

I don't crash, I do random gravity checks...

Yep smile also just to let you know. There are no brakeless bmx gods...they all run Gyro's.

Another option is using a easy out... basically it is a hardened drill bit that you would use in reverse (the drill). It digs in the bolt until it catches and begins to back out. If you do not have a dremel this maybe cheaper.

Thanks guys for the suggestions but I did it with a hand file and basically shaved the outside of the screw and I was able to unscrew it. But I am curious for more ways to recover a rounded bolt, just for the future because I am sure I will strip way more bolts

How about use the proper tools and dont try to tighten the shit out of stuff and not strip bolts?

Chill out man. What do you mean in proper tools? I have a pretty good quality allen set and a socket wrench, this bolt stripped so damn easy because it is so small.

Lol sorry I wasn't trying to come across as a dick lol

But use good, non stripped tools and dont over tighten stuff, especially bolts that use small allens...

I have worked with those bolts many times before and never had an issue with stripping. As Honda said, use the absolute correct tool & dont try to tighten it to absolute hell.

If I recall correctly, those bolts require a 2.5mm Metric Allen wrench, and when you use it, make sure it is inserted all the way into the allen broach & that there isnt any dirt or anything keeping it from doing so. You may find a standard size Allen wrench or maybe even a 2mm that "work", but that is a surefire way to strip out the bolt.

Then simply tighten it until the bolt stops turning. It's not a stem bolt, it doesn't need to be super tight. If you're worried about it falling out, put some blue loctite on it.

Hit the top with a hammer and the head will snap off.
Then just use super glue and a bit of wire to unscrew it
Or you could do what other people suggested and it would be way easier

Put brakes on and never take them off. Problem solved
