3mm stripped screw removal
 
Dunno where to post this question, so trying here.

How do you extract a stripped 3mm screw with sunk head? I did a search and all the instruction out there seems to be working on 4mm screws...

You need to cut slot with a dremel tool, using a cut off wheel and use a screw driver to remove it.

Most common way is a dremel with a cutting wheel -- cut a slot into the flat head of the screw, and remove with a flat head screwdriver. This method will also put a slight slice in your chassis if this is a chassis screw, though..

Something that is even easier for countersunk screws is to drill the stripped hex portion out with a 3mm or #32 or #31 drill. Once you get down to the shank of the thread the head will just pop off. Then all you have to do is take the component with the remaining thread off and grab onto the thread with some pliers and remove it. If there isn't enough thread to do so, you can then get a left hand spiral drill and drill it out. The left hand spiral drill will bit into the shank, and then once caught will unscrew it out.

This method is the best. Heat gun first sometimes loosens locktight before you strip head out. Then left hand drill bit. I just did this yesterday and had to drill it out.

Pro Grabit. A racers best friend and a stripped screws worst enemy.

Works 99% of the time to remove stripped screws without needing to resort to using the dremel. I don't know what I would do without mine. It has saved me and friends at the track numerous amounts of time and frustration.

Do you use a drill press or just do it by hand?

Does that kit remove all screw sizes on a standard 1/8th kit??

bigjayjay1 07-18-2012 08:50 AM

I have the grabit also but i prefer the craftmans ones they work and grab better this tool has saved my butt so many times so much less frustrating.

It does. The #1 bit and #2 bit can remove any of the screws, but the small #1 is used the most.

I've always just drilled out by hand. A drill press can actually be more trouble than it's worth for an odd thing to hold like a radio control car in some instances. I just find a solid workbench, put a couple blocks down to keep the chassis from sliding around and have at it with a hand drill.

I completely forgot about the Grabits/Easy-out extractors. As you can somewhat tell by my method I come from a more old school way, but the screw extractors are great inventions, basically doing the work of the method I described in one shot.

At the track hard to use this method you can buy the Grabits at Home Depot. The grabits work good but for me this one works better I have both. You can start small and move up if needed its only failed twice used more then 10 times 90% was under the chassis with threadlock.

I have had no luck with the craftsman ones. I just use a dremel
