Stripped threads
The screw turns and turns and never tightens. The thread in the plastic box has rounded off, so there is nothing left for it to bite on.
20 rods · 20 screws · 2 spanners
When a faceplate will not pull up tight, the threads inside the back box have usually gone. These give you new ones. A threaded bar with a spiked nut at each end spreads across the inside of the box and bites into the plaster behind, so the faceplate has two fresh screw points — no cutting the wall, no new box.
Two sizes, and they are not interchangeable. Measure between your two screw holes, then pick the one that covers it — or take both sizes and have the right one to hand either way. Each single-size pack is 20 rods, 20 screws and 2 spanners; the combo is 20 of each.
Fix the box, not the wall
A back box whose threads have stripped is the usual reason a socket or switch plate sits proud and wobbles. The proper fix is a new box, which means cutting plaster and making good. This is the other fix: a bar that spreads inside the box you already have and hands you two fresh screw points.

Two sizes
The only difference between the two is how far the bar spreads. The 86 type covers 69 to 82 mm; the 118 type covers 50 to 62 mm. There is a 7 mm gap between them that neither one reaches, so a tape measure across your two screw holes settles it in ten seconds.
For the square 86 × 86 mm box, the common single-gang size across Asia, Australia and much of Europe. The longer of the two.
For the long 118 × 72 mm box used for wide multi-gang plates. Noticeably shorter; it will not reach an 86 box.
One rod on each side of the faceplate. A pack of 20 therefore does ten boxes, with twenty screws and two spanners to tighten them.
Take the combo. It is 20 of each size, so whatever is behind the plate when you take it off, you have the rod that fits it — and a spare set of both for next time.

When you need them
Almost always the same story: someone has over-tightened the screws, or the box is old, and the plastic threads have given up. The plate then sits proud, rocks when you press the switch, and no amount of turning the screw helps.

The screw turns and turns and never tightens. The thread in the plastic box has rounded off, so there is nothing left for it to bite on.

One of the two screw lugs has snapped off the box. A rod spans the box instead and puts the screw point back where it was.

The spiked nuts bite into the plaster behind, so you can pull the rod up until the screw point sits where the plate needs it.

Plates come off for painting and papering and the threads do not always survive going back on. Keeping a pack in the van saves cutting a wall you have just finished.
How it works

Switch off at the consumer unit and check it is dead before anything else. Undo the faceplate and let it hang on its wires, or disconnect it if you prefer. You are working on the box, not the wiring.
Slide the block so the bar is roughly the width you measured, drop the rod in so one spiked nut sits behind the plasterboard on each side, and line the block up with where the screw needs to go.
Hold the block and turn the nut with the spanner until the spikes bite and the rod will not move. Repeat on the other side, then screw the faceplate into the two blocks as if the box threads had never failed.
Two rods and a spanner per box. The one thing that decides whether this works is the measurement — take it before you order, not after.
Compared with the usual options
Three ways out of a faceplate that will not tighten. Here is where this one wins and where it does not.
