Are expanding plastic wall anchor ls not a thing in the us? This is my go-to for everything, everywhere.

Wow, that is an impressive universal wall anchor.

Fischer is the shit when it comes to wall anchors

Fuck yeah, we got some of their epoxy wall anchors, that stuff is INSANE

I love them. €10 for a pack of 50, usable in nearly every kind of wall. My go to.

It's usually shortened to U W anchor

These are really cool. We of course have plastic wall anchors here, but I've never seen a fancy multi-use anchor like this. I'm wary about how much weight it would hold, though, especially since the Amazon listing doesn't seem to claim anything in that regard.

I did some digging on the manufacturers website and for their metric products I found the following PDF that calls out their strength in kN of holding for various surfaces:
A quarter inch is 6.35mm, so if you’re using say a 6x30 in gypsum fiberboard it would have a holding of 0.33kN or about 75lbs, which is generally what you’d expect from a plastic toggle.

There are tons of options at At Home Depot or Lowes. They usually have the maximum sheer load displayed on the packaging.

I used to Install tvs on walls and use these masonry anchors all the time. Actually it comes with the tv mount. Not sure of the exact strength of these but after screwing in 4 we can hang on it no problem.

I was just linking the German stuff because I didn't know what's common where you live. I really like Fischer and have used them exclusively now (and they are easy to come by, me being in Germany).
/u/calcium has linked the chart already, but for gyspum board you're basically limited by the material. I'd use a 6x30 or 6x50 for a single sheet. I prefer more holes to bigger ones in Gypsum, because you need to spread the load.
If you have a solid wall, even a shitty porous one (had old, loose, sandstone once) you want a long dowel so the load is as far INSIDE the material as possible. That way, you won't blow out the surface. Sometimes you have to lock the dowel in position, so it doesn't rotate before it starts expanding.

I am currently using identical anchors of 8mm for a wall TV mount. I'm a furniture/cabinet maker and I have also worked as a carpenters helper for a long time. I usually test stuff like this so I just hung on the extended arm for a bit. Didn't move a bit. Used 3 of those plugs. They're great. I used them in a brick wall btw.
Z-W-A-N-D t1_ixdzreq wrote
Also, I have these in 10mm diameter, I think they're 45mm long and they hold 215kg in concrete, 145 in brick, 25kg in hollow bricks, 20kg in bubble concrete and 15kg in gypsum boards.

I seem to have a vast assortment of anchors for different applications (toggle-bolts/drywall "snap-skru"s/expansions/grip-fast etc. etc.). Do these Fischers really do all of them that well?

I feel like you only need-need specialty anchors when you’re hanging something suuuper heavy (cabinets, huge mirror) and the rest of the time you can get away with these red and grey guys. They’re what I use for all sorts of things and I’ve never had a problem.
Fever_Raygun t1_ixd5vau wrote
Generally yes but for non-standard thickness walls they don’t work quite as well as a Molly/toggle

No they are a thing here.

This is what you want to use. Or something like it.
kuncol02 t1_ixd3cqb wrote
No. That is what you want to use and only that. They are so much better than normal plastic wall anchors that it's not even competition.
Maybe not in drywall. I feel like there you would be better with more specialized stuff.
DogRiverRoad t1_ixd5rlu wrote
Its a compressive hollow wall anchor. There is nothing exactly special about it. There are many wall anchors with similar or superior performance. I agree that there are wall anchors that are much worse, but that does not mean the a duopower anchor is the only acceptable one to use.
bobbertmiller t1_ixdhtp7 wrote
It's really a multi purpose anchor. It'll expand differently, depending on the cavities. It can either just spread in a solid wall or it can bunch up in a cavity.
AchillesDev t1_ixd4cck wrote
Those don't seem like they're made for plaster and lath construction, though.

These are the only wall plugs I use now. I never use the ones supplied with anything.
