How The fuck do i fix this loose crank on my bike? I tried socket

I forgot to mention that the bolt fasterner is inside the hole not outside so I cant use a wrench

Damn, that thing is stripped.

Can you get the other crank arm off? If you can get the drive side off, put some spacers on that dide and tighten it back up (assuming that arm is already tightened all the way up against the spindle). Should pull the other arm tight but it's more of a temporary fix.

Know anybody who welds, you could weld a nut on top of that stripped out bolt and try to remove it that way. But you will need a new bolt to replace it.

15mm socket. It's worth tightening it to see if it works, but if you rode it loose you more than likely need a new crank arm because the hole has worn.

It's not stripped, it's just a bad photo and your screen sucks.

Tightening one side on that kind of crank won't do anything to the other side, I don't know why you think it would but you should probably stop answering questions about bikes.

Have you built a bmx style 3pc crank?

On the iphone screen and from the description, it's either stripped as fuck or that lip is bent over. If the arms aren't both pushed all the way up the splines and OP can't tighten the left arm that is loose, he might be able to slide some spacers (19mm or 22mm?) on the right side of the spindle and then tighten that side up. It would pull the spindle and left arm up against the BB enough to keep the left arm from wobbling.

Assuming that's what is going on in the pic.m (left arm is loose, left bolt stripped)

Idk why you hate soda so much. Is it not salty enough for you?

But like I said my fix wouldn't be great for the long term because those cranks without pinch bolts are best pushed all the way to the end of the splines. I think I saw a chain guard in the OP pic tho so OP probably isn't going too hard on them.

No, I only ride and repair adult bikes, but I don't think that's a BMX crank. Looks like a standard low end cotterless crank to me, and I'd guess it's square taper if it's cheap. The crank bolt is hard to see because of the flash and the dirt but the flats are sound, and those bolts are usually 15mm.

Any 12-yr old with a bmx bike would be able to solve something like this for himself with a very limited selection of tools.

Ok, now look at that picture you posted and use your imagination and common sense here, if OP were to tighten the opposite arm, it would pull the spindle further to the side he is tightening, pulling the opposite arm up against the BB, and tighten up the arm that is stripped or he can't tighten for whatever reason.

If OP really just can't find the right size socket, he needs help beyond 4chan.
