Tips on how to remove stripped hex screws

As the topic title says.
It happened to me
I stripped the screw on my metal tail servo mount of t-rex trying to overtighten it
I tried to grab them by pliers, no luck. The heads are too small and round.
Does somebody have any tips on remove those screws without destroying the mounts?

usually i'd cut a slot on top of the screw using my dremel tool and open it with a flat tip screw driver.

Sometimes using a fresh hex tip helps. use a new allen key or cut the tip to have fresh corners. Also in these helis, sometimes manufacturer uses a mix of 1.5mm and 1/16" hex. The 1/16" is bigger. Using 1.5mm on these will strip the bolt.

Thanks, I'll try both. Maybe heating it up will let the loctite go, helping the screw turn.

Clean bolt head to remove any grease/oil, take a small amount of JB weld or thick CA and glue to head of bolt. this tip is in the RCheli mag, Jan edition.

If that doesn't work I would suggest using some soldering flux and solder the wrench on the bolt. This does two things, one, adheres wrench to bolt, two, it heats up the bolt only and what this does is "shift the clevis plates", the clevis plates are the threads. Let cool slightly before trying to remove.

Ive had a few instances where a flat head would fit into the head and turn it. Ive used a flat head on a few torx type screws before also.

You have to find the right tip that fits in tight, having alot of screws drivers helps.

Cutting a slot in the head is probobly the best as long as you can get the cutting wheel down into the head.

They sell easy outs also, its like a reverse drill bit that digs in when you spin it counter clockwise. We have a few of those around here

might not be but in the future some one on here may run into a problem similar with a larger size.

I may cut a slot into the nub that broke off in the nut on my king V2 spindle.

You bend it without the nut. LOL. It is thinner around the threads.

Craftsman has a SCREW-OUT set, part #952157 that works well. Directions say to insert the tool in a drill but I have backed screws out without using a drill. Just put the extractor in a handle and carefully back the screw out. My set came with 7 sizes of extractors all the way from large to very small.

I couldnt get any leverage so i put the nut on to use that tool to pry it with.

Ive bent it out a few times before it broke though
