Wie durchgedrehte Gewindeschraube rausbekommen?
Hallo,
ich habe eine lange Gewindeschraube (vermute M2), die auf halber Strecke aufgegeben hat. Das heißt, sie steckt im Gewinde und dreht durch. Ich kann sie weder weiter reinschrauben noch wieder rausschrauben.
Was würde ein Fachmann machen?
Gruß,

You can try to pull the screw out.
To do this, you take a fixable pliers (grip pliers), clamp them onto the screw head and turn them to the left while you pull them at the same time.
Or you put a matching spacer next to the screw, then take a small fork wrench that you, like a nail iron, clamp under the screw head and with which you then leverage like a rocker while you try to screw the screw out at the same time.
Turn the screw out under tension. So turn and pull simultaneously.
It didn’t work. But I noticed now that the thread turns.
I added some photos. It is a frame on which the pusher plate of the toilet is clipped. This frame is fixed in all 4 corners with screws (quasi in the sinker).
I must somehow be able to hold the threaded bush so that it does not rotate with the screw. However, I do not get through the small hole in the sink box with the pliers. not around the corner and then also so that I can close the pliers with enough force.
Anybody have a tip?
A better tip than a smaller pliers and squeezed fingers I don’t know now 😀 With luck, holding only with the fingers🤷
Yeah, thread can be cut. You just need the right tool and a good YouTube video for the basics.
Maybe it’s enough to clean the thread and screw it in a few times. Provided the thread is not too severely damaged.
The main thing is now to get the screws out first
Especially not for a merchant. 🤣
Just added two photos (photographed by the endoscope).
Can you cut a thread after? So an existing one? Don’t you have to meet the old one exactly?
Uff, my condolences Maybe thread cutting is really the best option to give the screw more clearance.
But the situation is really not beautiful😬
Hey, it’s not surprising if you don’t sit there. No problem. 😉
The threaded bushings are seated in the bottom flushing box. The box thus has holes in which the manufacturer has inserted threaded bushings: These have an outer edge (so they do not slip through and fall into the sink) and in the interior of the sink they are spread (similar to a dowel in use). That’s why there’s a risk that the threaded bushes will turn along.
The other screw is also fixed or fixed. the threaded bush rotates with… oh mann….
Unfortunately, I haven’t quite gotten through to what part of the threaded bushing ultimately belongs 😅 I’m afraid that it will have to be redrawn or at least the thread, otherwise you’ll meet the same problem directly. The second screw in the picture went smoothly? As probably should be… Before installing the new frame, I would always make several dry runs with screw and thread in order to be sure that the thread does not rotate and does not again block anything and then screw the frame. And clear, oil is ne idea, you can try 🤷
I will now destroy the outer frame that the screws hold (have just ordered spare frames). Then I can remove the inner white cover plate so that the hole becomes much larger and I better get to the threaded bush from the inside with a pliers (then I am closer to it = more force).
Just how do I realize that the threaded bush isn’t going through the next time? Fixing is somehow not possible (otherwise it would work with the constant). The screw and the internal thread may oil??? Then the screw should be at least smoother (the only thing that only has to hold the ductile frame). Anything else?
I had also thought, but then I looked at the pictures again and rejected the thoughts again. As it looks on the photos, the thread is nowhere on the front side and can accordingly not be pressed against a counter nut somewhere and secured against twisting. You can try it anyway
Can you consolidate the whole thing from the inside with (one) mother(s)?
If it’s twisted, the thread is probably over. If there’s really nothing left, it’s probably just boring out and cutting thread
There only helps drill. if necessary try to pull with a thread cutter for left thread. But this is probably too small.
If you have a supernatant, sweat. Heat material?
All a beautiful skirt
