You need a damaged screw extractor, something like this.
I've used most of these methods to remove stripped screws and they all work pretty well.
You can also buy a small drill bit for removing stripped screws that does wonders. This guy right here: https://www.amazon.com/EssentialTools-Extractor-Stripped-Hardness-63-65hrc/dp/B07GZ17QD9
Here is the extractor set I think would work if all else fails. I think there is enough meat left on those screws that you would be fine with the right tool but if not. here is the link for the extractor set
There is a stripped screw bit that counter sink drills into the stripped screw as the bit turns.
Similar to this.
Lowes, depot, ace, dixieline, osh will all have something like this.
Edit. Super glue will adhere better to a rough surface
Edit 2. Rubber band works best when you are applying all the force you can while only very slowly turning the driver.
I haven't used one on a gun, but easy out screw extractors have saved me when repairing bikes.
They are self tapping reverse threaded screw that you drive into the stripped head.
Link is for an example, not because I know that is a good version. https://www.amazon.com/dp/B07GZ17QD9/ref=cm_sw_r_cp_apa_i_Ga4hFbGS7CB7K
Try jamming a Torx bit in there. If that doesn't work, look in to extractor bits.
These things are awesome. With a bit extender, you can probably get into a deep hole.

There are drill bits made for extracting broken or rounded bolts. I bought a small set 10 years ago and have used them many times. It's a set identical to these.
https://www.amazon.com/dp/B07GZ17QD9/ref=cm_sw_r_cp_apa_i_S9WgFbS0061D7
I have a set like this and it essentially drills out a bit of the screw so you can flip the bit and it will grab and remove it. Super handy to have around.
Edit: Not sure if this one is small enough for that screw, but I bet there is a set for that size somewhere.
Looks like you'll need to get a set of screw extractors. They bite down into the wallowed out part of the screw so you can extract and replace them.
Something like this: https://www.amazon.com/dp/B07GZ17QD9
But you can find them at any hardware store.
Assuming it's in there quite solid... try putting a small screwdriver at an angle on one side of it... and then tap it counterclockwise with a bigger screwdriver.
If that doesn't work... https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9/
You should get a set of extractor kit. it is basically a reverse screw cutter, so you drive it in the same direction as loosening a normal screw, once it bites in, it will unscrew your stripped screw.
This is a first thing I googled, just as an example: https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9
Yeah, if you have enough access to dremel a slot in the screw head, that would be the simplest. Next best would be a screw extractor (example). Third, simply drill out the center of the screw until the remains of the head pop off.
The first two should yield a usable standoff/screw hole on the other side, but drilling it out would likely leave it unusable.
I have a set that I use specifically on HP notebooks when this happens. I can't find the set on amazon, but this is somewhat similar to what I have: https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9/ref=sr_1_5?crid=2TEI7KBVKGILY&keywords=screw+remover&qid=1647432926&sprefix=screw+remover%2Caps%2C96&sr=8-5
You could get these. I’ve used them more times than I care to admit:

Thank you for the response. I tried something similar with the product below but all that happened was the easy out screw started stripping and couldn't get it to puncture the bolt. Not sure if I got something too cheap or if I'm doing it incorrectly
Happened to me a few months ago. The plug is hollow so one of these fit and worked great: https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9?ref_=d6k_applink_bb_marketplace
I was at a hobby workshop on a lift so i would have been stranded without it. Go slowly.
You should try a screw extractor those little allen screws (usually) don't have a lot of torque on them, but might not be the case here if the previous owner stripped them. If they added loctite that could also make it trickier.
I bet if you call S&W about it they would fix it for free.
Screw extractor bits are handy to have; they're designed to make an even shaped hole (possibly not needed here for a stripped hex head) and then the other end will bite in and remove the screw.
Otherwise it really depends what tools you have available; you could do anything from grinding a slot for a large screwdriver to drilling out the head entirely to spot welding a piece of metal to it that you can turn or just finding something that wedges in tight enough to turn it.
This kit has saved my ass multiple times when dealing with Benchmade's lead-based screws. Just make sure there's a correct sized bit, there's a lot of kits available like it, I'm just giving the first one I found as an example.
https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9
Best $13 spent when you regularly build anything that involves screws
I highly recommend this set.
They come in a cobalt option if you can find it choose that one. If not any of them are good enough.
They really are amazing and can handle these small screws.
Screw extractor. Here's an example link. You'll still want to prep it by using some penetrating oil like "Liquid Wrench".
If that doesn't work then drill them out. You'll probably have to clean up the threads with a tap. If the thread area is destroyed then you'll have to use a larger drill and tap for the next size up of thumbscrew.
Use a screwdriver instead of a hammer next time.
I'd try something like this, but you're really in a bad way here.
That scratch would have to be pretty deep to break the contacts of copper. Hard to tell.
They make screw extractors just for this kind of thing. You won't even need to drill out the socket as you've already got a hole to start with. Yeah, Amazon wants $12 for it. Your local hardware store probably has one in stock for $20. Since you've already gotten the screw out by now, you may as well order the cheap one so you'll have it next time. Because there will always be a next time. ;-)
Yeah that's a hard one. I'm pretty good at drilling and tapping but I'd worry about how far to drill in too. You could try a screw extraction bit first that don't always work but it would be worth a try. https://www.amazon.com/dp/B07GZ17QD9/ref=cm_sw_r_cp_apa_fabc_RWGcGbCG035JC If you drill it out I'd probably use a #30 bit. But that would be just for an m5 screw. Go really slow. A couple turns then wait for it to cool down. Stainless heats up fast then hardens. It will ruin your bit and make it harder to drill. Then rethread it with a plug tap.
You can try using some pliers to grab the end of the part and try to unscrew it out. I’d spray some Kroil, PB blaster or WD-40 on it before to help it come out easier. If you can’t grab it with pliers a screw extractor will work. here is a set off amazon I’m pretty sure you can find these at almost any hardware store. They come in handy when stuff like this happens.
Heres what I could think of:
Use one of those things for removing damaged screws, if they go this small. For example: Amazon - screw extractor
Dremel a little slot in them? Of course, you'd ruin your handle scales.
Super glue or epoxy the torx key into screw. S.G. would be easier to undo for multiple screws and to clean off the knife.
As above, but a little dab of solder
First try a thin rubber band between rounded hex bolt and Allen key.
If too thick, try a piece of latex glove. This method is better than tin foil.
If these fail try the other methods mentioned. Cutting a slot in the head with a dremel remove with straight screwdriver best. And yes as mentioned, a Torx bit beat into the rounded hole may also get u out of this situation. Lots of good help here. ; )
https://www.amazon.com/dp/B07GZ17QD9?ref=ppx_pop_mob_ap_share
If all else fails, weld a rod onto the head, twist off. ; ) but yeah... that's overkill... and best for big heavy duty bolts.
U can try these: https://www.amazon.com/dp/B07GZ17QD9/ref=cm_sw_r_cp_apa_i_kU2hFbRVMV5WG
Or instead of a rubber band, try cutting a small piece from a latex glove
Or try a small flat blade screwdriver, but punch it in if u can first. Get good straight pressure to break it loose first shot.
If u can slot it with a Dremel, that would be best.
Tiny vise grips if u can clamp on the outside.
Can also tap it around (unscrewing it slowly but surely) with a small chisel.
U can also use high strength epoxy and a small rod on it.
Big stuff u can tack weld a rod or another nut on top.
I carry this tool with me all the time.
It’s one of the only as seen on tv things that is actually genius.
Cheap and easy I promise it will work.
Or just get yourself a set of these. Best $13 you’ll ever spend.
You'll want to use a screw removal kit. You'll have to find the right size to use, but they're really effective at removing stripped screws. Obviously you will need to find a new screw for the machine afterwards. This method does destroy the screw more, but it's unusable already, so no harm there. Here's an example of what they look like so you have a decent starting place: https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9
Mercs mechanics need to get one of those screw extractor from Amazon...
https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9
There are specific bits for removing stripped screws. Look for one of [these](https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9) sometimes you can find single bits in just the size you need but the sets are nice to have
You could just use one of those screw extractor bits to cut right through the paint since you're tossing them anyway.
Get one of these
get a set of something like this:
https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9
at Home Deport or Lowes. They're handy for more than just broken nozzles.
Your best shot may be to get something like this: https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9 . It has one end to make or widen a hole, then the other end has a reverse twist to latch onto and screw it out.
Do you have any torq bits? Their star pattern can sometimes grab a screw like that. Otherwise grab a screw extractor off amazon.
Maybe: https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9
Have been in the same situation.
You need a screw extractor screw extractor something like this. Worked like a charm for me
Maybe an ezout stud extractor? I have a set of them and they have saved the day a few times for me. https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9/ref=sr_1_2_sspa?keywords=Ez+Out&qid=1665250578&qu=eyJxc2MiOiI1LjM5IiwicXNhIjoiNC45NyIsInFzcCI6IjQuOTMifQ%3D%3D&sr=8-2-spons&psc=1
ooow now i see what you mean, Yeah thats a doozy.
First thing i'd try would be using a special screw extractor. Its a drill bit you can buy for as low as 5 bucks give or take. This would be the least effort for removing. Yet im not sure if the size of the screw isnt to small. Most of these extractors go as low as 2mm thread.
https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9?th=1
Above ive linked a cheap set as example.
If that fails the only thing to do is drill it out and repair the thread. This can be done by drilling out he screw, note that you dont drill to big else it will be become 10 times as difficult.
After drilling a new hole you can use a thread repair kit, this will thread a new hole in wich you can insert the thread insert that will serve as thread for you're screw.
Above again ive linked a cheap set as example,
PS. If you by accident drilled the hole to wide, you could still fix it. But that will require you to weld the hole, drill again and just tap the hole to the correct size of the screw, note that if you weld you won't need thread repair kit but you wil need something to tap the thread with.
Hope this helps
Angle grinder or oscilating tool to make a flat slot to get a flathead into.
Barring that, a screw extractor.
you can try this , you could try pliers
You could try a screw extractor.
This screw extractor kit works wonders getting out stripped screws. Check this out! https://www.amazon.com/dp/B07GZ17QD9?_encoding=UTF8&psc=1&ref_=cm_sw_r_ud_dp_76EYVH8ENBQBKAJ32538
Get this thing https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9 and a halfway decent drill. Start building that tool collection. The stripped screw device will get you out of many jams. Then take the machine screw that is stripped and take it to the hardware store to get one just like it. Most hardware store have a place you can partially screw in that screw (or another one from the dryer) to get an exact match.
2 that come to mind.

This style is more or less our go-to at the shop. It doesn't always work, of course, but it has a higher success rate in my experience than some of the other styles. The one thing to know is that the "drill" side of the bit is cut for REVERSE drilling, so as to not further tighten the bolt. A few guys have definitely dulled it going the normal direction. Use low speed on your drill.
Biggest tips are to use a lot of a penetrating lubricant or similar product. I've been liking Finish Line's Chill Zone lately. If the bolt head is indeed sheared off, you want to try and start your drill in the center of the bolt shank. This can be really hard to do, but my advice is, if you can, filing the metal flat and then using a center punch to set your start point. You'll likely still drift a little but it's all about small incremental advantages.
FYI blue threadlocker isn't that strong, you could try something like red threadlocker, or maybe just soak the fork and bolts in like salty water and leave it outside for a few days? lol, not really sure. Never intentionally rusted something before. But rust is your real enemy, not threadlocker. Also, another FYI, you're probably talking about M5 bolts, those are the most common size on frames and forks. M4 is mostly only found on derailleur limit screws.

My nephew had an accident on his bike and ground flat the bleed screw! I successfully removed with a damaged screw extractor kit.
As for where to find a replacement, first you need to find the correct part number as Shimano has multiple versions of this screw. Go to https://si.shimano.com/#/, enter your brake model number, and click on EV (exploded view) document. The part number will be on the sheet. If you can't obtain part from LBS or your favorite online seller, try ebay.

Sorry for the tardy response. I went to amazon and bought this. It removed the stripped screws fairly easily.
https://www.amazon.com/dp/B07GZ17QD9/ref=cm_sw_r_sms_apa_i_xhoQEb01NJEZW Set on amazon, you don't have to get those but that should work for you
They make screw extractor tools that drill into the screw and bite into the damaged head enough to remove it. $11 on Amazon for a basic set. https://www.amazon.com/Extractor-Stripped-HassleFree-Hardness-63-65hrc/dp/B07GZ17QD9
The specific one I bought isn't available on Amazon anymore, but this one looks pretty much the same:
I have taken out a few striped ones on my krytac with a specialized drill bit extractor for stripped screws...with a decent drill/electric screwdriver and patience it works.
