How do you unscrew something when the screw head is worn down, /diy/?
you drill it down, break with various tools the remaining of the screw and take it out, get in new screw.
Done it dozen of times, aways works. When I am lazy I do this with clenched rusty stuff too.
>break with various tools the remaining of the screw and take it out,
Appropriate size easy out.
he fucked it up this bad already and now you want him to tack off a alan key to a screwhead?
>let me bust out the mig rig and pray
I see, well the words dont seem to match very well.
get in - to go inside of, or inside of
hot - of a high temperature
hammer - a tool used to impact nails, or to hit something
a screwdriver bit for a drill was clear
Are you saying to heat a screwdriver up and then force it into the screw so that the screwdriver will melt into the shape of the screw head?
"you will punch the grooves and its good as new"
I get the impression that you are talking about the threads of the screw, but punching them would mean stripping them out. If you mean to chisel the screw through the other side of whatever it is in, that is assuming the other side is exposed but that would also mess up the threads so that a new screw couldn't be inserted without a tap and dye set.
As someone who has stripped every screw he's ever touched at some point or another, I've never understood this method.
What conditions need to be met for it to even work? Lord knows I've tried it.
Usually just drill/dremel the sucker anyway, but the rubber band style has always had me curious.
He is not me, what I mean is you get the screw head really hot, the use the bit and hammer to punch in the pattern. The idea is to get the screw soft enough to let it deform around the bit, then when it get hardened again you can just unscrew it.
I hope you understand, because I can't explain any better.
looks like a hex-screw to me, maybe he tried to use a torx on it?
or it was a torx and he tried to use a hex....
also some hex screws included in chinese stuff just seem to be made of butter!
I use a machinists "center drill" to drill the head until it falls off the shank after which I remove the part the screw was securing then remove the screw by twisting the shank with a visegrip.
There are many ways of course depending on head access and available tools.
Came here to post this. A dremel and a bigass flathead gets 80% of stuck screws/bolts out. If the head is all the way broken off or you strip the slot you made (done it) I get out the tungsten carbide drill bits and the screw extractors or just drill the hole bigger and retap it.
not him, but fuck security torx.
if you don't have the bit for it (in the right size, no less), leaving the house/shop/whatever is a pain in the ass, especially if you already have a dremel.
If your fastener is stuck hard enough to strip the head out, you arent going to break it free with a rubber band.
If you DO break it free, you wouldnt have stripped it in the first place.
I am the guy who rage against torx destroyers. I am agree, today you can get some torx tip for a negligible price. Especially because you have to deal with torx and security torx everyday.
For the others :
Torx start to replace Phillips and Pozidriv on many manufactured products. When you buy tools from e.g. Wera, it is security torx. A high quality set is not that expensive. I use a Dremel too, but only if the screw is completely destroyed.
Just remember one thing, a good job need a proper tool, and a good quality tool. Tools, that need to be cleaned sometime and must be organized. You can't be a good worker with china manufactured shit. Exception for the tools that deserve to be used one time. The Dremel solution must be the last thing you are thinking about, when nothing else is possible. You run the risk of destroying the device you try to fix, even if it is only aesthetic.
But remember, a proper tools for a good job. I have the set on the picture, I will not use a third of the set because it is more for aeronautical application, but I have a decent tool for a good price. The point was the portability which is very important to me.
