I was changing a set of grips, and while tightening a screw the bloody head snapped off :( ...devestating. The rest of the screw is threading in the hole. How do I get it out??? It's a Beretta 92FS...do I puch it out, and order in a factory replacement??? (if at all possible)

Any help would be greatly appreciated:cool:
 
you can use whats called an easy-out bit.
you drill a #40 or smaller drill hole into the middle of the shank and tap in an easy-out with a small hammer then use a tap handle or vise-grip to remove it counter-clockwise.
or,if you have some "meat" to grab then carefully dremel a slot for a small screwdriver and get it out that way.
 
Flush or is their a bit of meat to it? Can you take a finely ground punch and gently tap it out counterclockwise? Can you use a dremel to make a slot in it?
 
Grind a slight flat in it and grip it with vice grips and try to turn it back out. Hopefully it backs out with less force than it took to snap it.
 
generaly the head of it holdt the torque so have you tried just pushing your thumb on it really hard and turning it has worked for me in the past i hope it can work for you

What he said..........but when I drill it I use a left-handed drill bit. When your drilling the hole (with the drill in reverse) sometimes you will get lucky and the drill bit will catch and wind the screw out.
 
It shouldnt take much force to extract. All(or a very high percentage) of the pressure was being held at the face of the head, as you found out. If you are using the centre punch method to spin it go VERY easy with a sharp,small punch cause every time you hit with a C punch that metal flows outward and you will lock it in worse. Ideally,and depending on your machine ability is a hole down the middle. most often turning the drill bit around and crazy gluing the shank in the hole(extra care not to glue threads)is enough. Like one fellow said, you arent looking for much
 
I am not suggesting you do this... but I have seen a guy build up a broken bolt with weld and then use vice grips to remove it. It has the added benift of heating the bolt as well.
 
Have a look at the other side, think the bolt opening goes straight through so can use drill press to just drill the screw (not the threads, small bit) and set the depth so not too deep/not touch opposite grip.

Perhaps thin dowling dipped in crazy glue stuck onto the bolt.

Be careful with tapping and such as the frame material could be very soft (aluminium alloy) and threads could be damaged.

If really worried, a smith has probably seen and dealt with this issue numerous times.
 
Epoxy glue another screw on top of the broken screw. When it dries try turning the whole mess out. Just an idea. Might work. Other than that, off to the smith you go.

If it's not too late and if you have basic skills/tools here is what I think you could do:

Check the size of the broken screw (this set removes screw sizes #4 - #16) and if it fits buy one of these:

Hope this helps and good luck.
 
Take it to Casey, pay the man his due, and you won't end up with a buggered up frame. This is one of those situations where I'd be tempted to do it myself but would be better off leaving it in the hands of someone who's done it more than a few times.

Isnt that the case about 99.9% of the time though but where is the fun in that? I also recommended a smith but probably not smart enough to do that myself until I made a bigger mess of it.
 
By all means, if you don't have the patience, and the skill to remove this on your own, don't touch it.Take it to a professional, before making attempts on your own.It'll winding up costing you less if you don't make a mess of it , before you take it in.
I wish I could get this through to the millwrights and set up guys at work.If you don't have experience taking out broken screws and bolts, you can really make a mess of things, and make it a lot more work and frustration for the guy that winds up taking it out after you give up.

The screw is quite small and a few of the ideas above are good for big screws but those easy outs above are big enough to take 1/2 inch bolts out!

I have the screw and the insert bushings in stock. Give me a call if you like.

I thank all those above for confidence in me.
