I'm trying to change the handle bar on my bike, and one of the screws on the right hand controls is stripped and I cannot figure out how to get it out. Can anyone give me some ideas??

 

Could drill it out. Will most likely ruin the threads so then heli coil it after that

 

Which screw?

If it's a clamshell housing screw, drill off the head and the clamshell will come apart. You can then grab the shaft with a pair of vice grips.

I had that happen to me. Replacements at Ace.

 

This one.

 

You should be able to drill that and then remove the shaft with a pair of vice grips.
Be careful drilling it so that you don't over drill and get into the shaft of the screw.
Go gently with a drill bit that's the size of the bolt shaft (3/16"??) and take it slow. As soon as the head comes loose on the drill bit and starts to spin, stop drilling.

 

You could also try an easy out. I've backed out many stripped screws using one.

 

It's worth a shot at first.
I never seem to have any luck with them but sometimes it seems like I'm the only one that doesn't.

 

Huh, must just be your luck. I've always had the easy outs work on aluminum screws. Now, hardened bolts and such... I've had no luck with them either.

In the pic the OP posted, that screw looks like a typical aluminum screw. Another thing I've done in the past is used a small file and filed a slot into the screw head and then used a straight screwdriver to back it out.

 

The screws on mine are steel, not aluminum.
You can also sometimes get a torx bit that is a tight fit, tap it in with a hammer and use it like an extractor as well.
Lot's of options.......all of them suck compared to a non-stripped bolt.

 

My favorite technique is using a Dremel to make a slot, and using a big fat flat blade screwdriver to remove it. I've had to do this a few times on rounded Allens, thanks to the yo yo's who worked on this bike prior to my owning it.
