stripped screw dilema....... HELP

[iluvmud]

So, after acquiring my TA02W Nissan 300 it makes me want to revisit my Nissan GTR kit which is pretty much the same car.... one problem I remember having and it still needs to be fixed. I know the dremel way which cuts a slot into the screw head, but the dilemma is its a countersunk screw so that wont let me dremel deep enough without hitting the chassis. I have a stripped screw on the bottom of my FRP chassis that I want to replace, which brings me to my question

- what is your best way to remove a stripped screw?

Suggestions?

You can buy a reverse cut drill bit and try to very slowly back it out. If you go slow enough with the drill bit, it will bite into the screw and back it out. If you go fast, it will just drill out your screw and be a pain in the you know what.

I have a few suggestions depending on the specifics of the screw.

If its not completely rounded off/stripped out.

1. Try tapping the screw driver with a hammer to break the corrosion, and help it grip the screw head better.

2. You can buy valve grinding compound from auto parts stores. You dip the screw driver tip into the compound to get a tiny blob on the tip, then turn the screw out normally. The compound actually grips the metal to metal contact with a higher static of friction, which makes the screw come out easier than totally stripping it. This tip is actually from working on motorcycle engines as their aluminum cases and steel bolts cause stripping problems.

If its completely rounded off.

1. Try beating the screw driver with a hammer to help it grip the screw head better. The difference here is putting a good beating on it rather than a couple taps. The idea is (if possible) that you are reshaping the metal of the screw to have something to grip.

2. You can buy "EZOuts" which is a tool set for extracting broken or stripped screws and bolts.

3. If possible, sometimes you can heat the screw with a torch to make it come out easier.

4. Drilling it out. It sucks, but sometimes its all you got.

8/10 times the screw /bolt unscrews with the left handed drill, maybe a bit small, but ive found this kit useful, as if it drills through, you've an easy out the right size.

I've had to run a dremel cutting disc on a rock in the garden to get it small enough to not damage surrounding parts,too much.

Also a small tap (M3 etc, not a kitchen sink one! 🙄), they normally have a sharpish point, which you can hit the screw around with.
