Not a computer question, but I am sure someone will have the answer.
We have a UPVC double glazed rear door, with a full length metal strip attached for the locking devices. The metal screws holding this are loose, and attempting to tightening the screws points out that fixing holes in the UPVC are enlarged, so no longer forming a grip.
Tried a couple of methods without success, including getting next size larger screws. No point in re-drilling a whole series of holes in the metal strip, then forming new holes in the UPVC, because the thickness of the UPVC walls are suspect. We have some 'hard plastic' glue, which can be used on UPVC, but it is not suitable for metal, so that as ruled that method out.
Can you recommend a method or a suitable glue, that will lock the screws and UPVC, so making a secured fixture?.
The framework is enclosed, so no chance of building behind the thin UPVC wall, it can only be 'pasted' on the showing face. There's a thought worth considering. Build a 'bridge' over the hole with Araldite or some similar component material. Then re-drilling a very small starter hole?.
If you can put up with the thickness of the head then several of these click here with a bit of glue would do. I could not find the name of the ones I have got as they are in the workshop and it is scardy-dark down there at the moment, I know where they are - as far from the door as possible with two disassembled carriages in the way on the floor. the rivet bushes work like pop-rivets and the front portion is thin and has no thread so it expand to grip the panel you put it through. If you have an electronics assembly firm near you they may have them to put in their cabinets to screw panels onto.
