I've put up my own shelves with proper brackets.
But I see these "floating shelves" advertised. I thought,
"What's holding them up?" Apparently there's no right angle involved,
just a screw going straight into the back of the shelf out of the
wall.
How can that possibly support anything?


Here's one style :

It doesn't say how big the two screws on each support are,
but why don't they just get ripped out of the wall?



The " Instr " link on the web page does give more details :
" secure the base plate using a #8 x 1-1/2" (or longer)
flat-head screws "
.. that's for wood studs ; for metal studs - read the Instr. .
The weight bearing ability is in the product description.

A 1.5" screw doesn't sound like it could take much sideways force.

There will be a bit of friction between the shelf mounting plate
and the
wall itself if the screws are tightened properly in the first place.

If the walls are anything like UK walls, the wood used is cheap softwood and can't take much force.
