How to remove Allen screw that is stripped

[deltaecho]

My son has a Savage 110 that has a stripped out allen screw at the rear trigger guard. How do you get those out? I was thinking of drilling...but in the back of my mind I remember seeing some sort of chisel that you would hammer and it would turn the broken bolt/screw out.
Thanks in advance!

Snap on and Matco make tools for getting these out.

There is a tool which comes in different sizes for different size screws called an EZ-out. You use the drill size it calls for then use the EZ-out.

You can try a "torx" head (same size) has more teeth...works about 75% time.

Are the threads stripped or is it the sockethead where the allen wrench fits in? These are two different problems with different solutions. If it is the head that is stripped, I have had success removing them by using either a star bit screwdriver bit that almost fits but not quite tapped into the hole with light hammer blows or the square type EZE-out, again find one that is a tight fit in the existing socket without drilling first. If the threads are stripped and it just spins in the threads without backing out; you need to apply upward pressure on the screw as you turn it so that good threads can gain a purchase on the threads. Be careful what ever you try because removing a broken screw is even tougher.

I believe I have seen a post here about using either red Locktite or JB Weld then remove the screw and toss the wrench and screw away.

Thanks for all the options! I should have been more specific in mentioning the problem though...it is the head is stripped out...at least that's what I know so far. Hopefully, the threads are OK so I can get the screw out.
My son was kind of bummed, because he wanted to get the stock off and start a re-finish job on the gun. I have a couple star shaped screwdriver bits that may finally get some use this afternoon.

I've had a lot of luck with a small spring loaded center punch. If you have a Harbor Freight nearby, you can get one for about $5. Put it toward the outer edge of the screw at an angle in the direction to loosen and start popping it. It may take several times to get it started, but once it breaks loose, it will usually come out pretty easily.

Might try a metric size or vice versa. Find one that won't quite fit then grab the hammer and force it in. Usually loosens the screw with all the pounding. Next is drilling, you have to use a drill big enough to drill out the allen hex area and when it breaks through the head the head usually comes off. You then can pull the trigger guard and hopefully the stock. Then you should be able to remove the screw with pliers.

if you don't have an impact driver, you should get one.
