Hollow wall fixing which leaves the screw proud of the wall

The smallest diameter of screw now seems to be 4mm, I am pretty sure sometime in the past I managed to get 3mm. The other important consideration is the thicknesss of plasterboard they are being fitted, too short a length and they will expand within the plaster rather than behind and pull through as you tighten the screw. Don’t ask me how I know.

I shan't; thanks for the tip.

But which of those, if any, has a small enough screw head to slot into the back of the router?

Even with some fixing that spread out of the back will still be spread out if you slacken the screw back off

I assume a keyhole type hole on the back of the equipment. In my experience a micro adjustment of the distance between the screw head and the wall can make a large difference in how well the equipment is secured. If on first fitting the item still moves remove it and tighten screw by a quarter turn etc.

These things seem effective:

any form of glue helps those thongs work.

Ive often used simple plastic 'Rawlplugs' . They will hold a picture up, for example.

But you have to drill accurately and use the right self tap or wood screw.

If a section of plaster rips out, a car body filler repair skimmed over with plaster is excellent.
