Stripped an itty bitty screw w/ an Allen wrench (Walther P22)

This should be a very general question but nothing came up in the search function. I've never really worked with stuff THIS small and delicate (brakes on a car are much easier :) )... so I thought I'd ask here.

I seem to have stripped a very small screw on my Walther P22. The "worm screw" that helps hold in the extra weight on a 5" barrel setup. I've taken it off and put it on, oh, four times now. Must be some weak metal for me to strip it that easy -- so I surely want to try and replace it with something harder. Then again, maybe I should just try and "snug" it in there from now on.

It's an allen wrench screw, I beleive 1/16th in head. It's length is just 3/32nds of an inch from eyeballing it. Yeah, I'm an idiot. The bugger is STUCK in there it seems.

Can anybody recommend a tool to remove something like this without damaging anything? Sources for such tools?

The next size up TORX bit will be a good choice, tap it in and will swage the corners of the hex just a bit for the teeth to bite into. Another helpfull method is to stretch the screw to relieve the tension on it making it easier to remove, put in the socket a small pin punch or a cut off piece of the wrench and tap it firmly with a hammer. It stretches the bolt head slightly from the screw-threaded portion and releases a lot of the tension that is fighting you in removing it. You might also luck out and have a metric hex key fit the wobbled out socket of the screw head well enough to remove it once the head is stretched back a little.

...and an allenhead screw makes a nice center for a drillbit, should the occasion arise.

If you can find a Torx-head screw as a replacement, you'll be way ahead of the game.

Hate it when that happens....

Check your allen wrench, make sure the edges are still sharp, not rolled over. I've used some coarse valve grinding compound, dab a little in there, if it's not stripped too bad, it will allow the wrench to get a better bite.

Good luck!

Bummer! Just have one thing to say about using allen wrenches. Make sure they are bottomed out. I twisted the head off a grip screw a couple of days ago with my stubby screwdriver and had to jerk the bushing out with the good old vice grips. I couldn't find the right tap and was doing the dumb stunt of trying to recut the threads with the grip screw. I saved the head of that screw in a plastic bag to remind myself one more time not to do this dumb stuff anymore! Oh Well..................................................some people never learn , and I am one of them.

You can usually get an Allen screw out with an Easy Out; if it has a point, you might have to grind it flat.

I suggest replacing it with either a straight slot screw or a Torx screw, even if you have to drill and tap to a U.S. size.

Just to make myself clear: I hate Allen screws. I hate Allen screws. I hate Allen screws.

I agree with Jim! The only thing I hate worse is slotted screws boogerd by a five thumbed clutz who can't manage to unscrew a screw right! I love the allen head screws for grips on 1911's and I like the Ed Brown Hex mag catch lock screw for that reason. I have to work with slotted soft screws on six guns still and i hate them because they are easy to ruin. It is not easy being a perfectionist!
