Would be more useful if it covered more types and showed what weight each could support, but not a bad start.

Unfortunately some fittings require a screw to be screwed into the wall and
the item slides over it on a keyhole plate. Many of the plugs need the
screw to be tight. What is the solution?

I also believe that the modern screws are not as good as the old
woodscrews. They had more of a tapered thread root which would act as a
wedge and open up a plug. Newer screws tend to merely cut a thread into the
lug and they are parallel.

Hollow wall anchors are ideal for this.

My experience is the opposite of this.

The problem is that if the plug gets pulled back out by the slightest
amount the wedge shape results in it becoming *very* slack. Also the
greatest amount of expansion is at the start of the hole, often in
plaster which is likely to crumble and loose grip. The tip of the plug
expands much less near the bottom of the hole where the substrate, will
be much stronger and provide a much better grip if there was more expansion.

Decent plugs will expand if you use the correct size screw.

Yes. Because plasterboard crumbles, the best fixing will spread the load
over the back of it. A normal wall plug which simply expands can also
split the board if close to an edge or hole.

But with some of these anchors, you may need to change the screw to
countersunk.

and of course if the wall is plasterboard dot&dab onto a solid base
(brick or block) then a few of the fixings won't work at all. Obvious
to most of us maybe, but not to everyone.

I remember coming home cold from the sea many winters ago, and half leaning against the wall, half sitting on the storage heater in a rented house. When I defrosted I went to stand up, the heater fell off the wall. Wrestling with 70kg of bricks is something I do not want to repeat. When I re-attached the heater, the screws went into the studs, where the should have been in the first place.

Dot & dab is the spawn of Satan!
