Repair of plastic screw fasteners

Repair of plastic screw fastenings
This is a very common phenomenon when a bushing with a thread in plastic products breaks. This can happen both from exceeding the twisting force, frequent disassembling of the node, and from the aging of the material itself. After all, products made of plastic or plastic are not eternal, and over time they lose their original properties. It's possible to restore the screw fastening, and one way I'll show you now.

The following materials will be needed

  • Thin steel wire.
  • Insulating tape.
  • Tube for insulation of wires.
  • Adhesive for plastic.
I would like to clarify about glue. I used the universal glue "Gorilla", which is sold in America. You can use any other glue that must necessarily be used for gluing plastic parts.

Restoring the bushing of the fastening

Before the description I want to say that I made repairs of two bushings: one is destroyed almost entirely, the second is less than half.I say this so that there are no questions about the photo, since they may not have the same sleeve. Start the repair. The first thing you need to pick up the rod or tube, close in diameter to the plastic sleeve. We wind the wire on the frame.

Adjust the size of the spring to the length of the sleeve.

Biting off the excess, check. The spring does not protrude, sits tightly.

Wrap tape over the spring. This should be done so that the glue does not spill out, which we will pour into the sleeve.

At this stage glue could be poured, but then it would have to be drilled with a screw. To not do this, you need to insert a cambric or a tube for isolation into the hole of the sleeve.No glue will flow into it and the hole will remain whole.

The tube is boring to choose a smaller diameter than the hole.

Insert the tube all the way into the threaded hole.

And now we are pouring glue.

While the glue is not stiff, tear off the electrical tape around the spring. It is not necessary to do this at all, but if you decide to do this, act until the glue has finally stiffened.

Cut off the bulge with a blade from a clerical knife for a little face.This, too, needs to be done before the glue hardens completely.

The restored sleeve looks like this:

It looks terrible, of course, but who cares, it is located inside the case. You can use a plastic mount only after the glue has completely dried out. Like everything dried up, I assembled the dashboard panel. Experience has shown that this recovery experience is quite viable.
