Beginner question - which screw? And will the construction hold?

[specter]

1. I am going to screw up a long ceiling track in the ceiling. The ceiling consists of 13 mm gypsum and then wooden studs. I believe screws that are 25-30mm will definitely suffice (going to hang curtains there later).

But what kind of screw should one buy? Wood screw or drywall screw? Please explain the difference with



2. I am going to put up shelves in the garage. Quite substantial ones, 60cm deep and 235cm long, see here: https://www.byggmax.se/förvaring/hyllor-och-hyllplan/hyllplan/hyllplan-i-furu-p09126

Will these hold if I use these brackets? 30x25 cm. https://www.byggmax.se/förvaring/väggskenor-och-konsoler/vinkelkonsol-p25721

These are attached to a wall where there is first 13mm gypsum and then 17mm tongue and groove planks. Regular wood screw 30mm?

Will the entire construction hold for heavy loading later?

Use slightly longer screws so you get full engagement in the råspont (45mm?)

1. Choice of screw matters less in this case, as long as it fastens a few cm into the wood, no large loads.
2. Depends a lot on how much weight you will have on the shelves, I would have chosen another type of bracket in a thicker model. Screw depending on bracket, don't forget to account for the thickness of the bracket so the screw doesn't just fasten in the drywall.

I would prefer not to screw inside the råspont as there may be pipes, electricity, water, etc., there.

Question 2.
Do they risk being too weak, the brackets?
Going to put up quite a few shelves so there will be quite a few brackets, so I thought the price of 15kr each was reasonable ;-)

Maybe I can use some of these and complement with 2 sturdier ones per shelf, for example these? http://www.jula.se/catalog/bygg-och-farg/forvaring/forvaringshyllor-lador/konsoler/konsol-341061/

it is probably the depth of the board that causes some trouble, the torque increases the further out you are from the attachment. It would be unfortunate if the shelves start to slope when loaded. It will surely work well with those from Jula, and it’s possible to complement them later if needed.

How heavy items should you load. A 20-30 cm bracket on a 60 cm shelf is too little if you’re going to load heavily. A 30 mm screw is really tiny. I think you should use 4.5x60 mm or similar. The risk of damaging something in the wall is minimal, right?

In terms of brackets, I would rather install Elf tracks with accompanying brackets about 50 long. But ideally, I would use floor-standing storage shelves if I were loading heavier items.

Make sure the curtain rail goes at least a couple of cm into the stud. So at least 45 long, I think.

Hmm...maybe I should switch to 40cm depth on the shelves.
Do you think the brackets from byggmax that I linked to will work well then?

If it had been me, I would have instead set up tracks with brackets that hook onto the tracks. They are also available at Byggmax. It becomes much sturdier, and it's easy to move the shelves around later if you want.

The brackets are too weak in the garage. One might try to convince oneself that heavy items won't be stored there. Then the winter wheels and a lot of screws and nails go up. Additionally, the fastening is too weak in 17mm raw plywood. You need to screw directly into the studs.

Drywall screws are meant for fastening drywall to studs. There are drywall screws for wood studs and drywall screws for steel studs. The difference lies in the threads. Nothing really holds in the drywall itself. There are various types of screw anchors that hold decently, but don't expect them to support any load at all. In the ceiling, probably only Molly bolts work. Ray-fix and the like I wouldn't use in the ceiling.

For Molly, you need an installation tool. For about fifty crowns, you can find a Molly pliers at Jula or Feltema that will last your lifetime. Molly original is, of course, laughably expensive. That's why cheapskates like myself mess around with a large flat screwdriver and a crowbar instead .

By the way, I agree with Tosse@ on Elfa brackets. You can find knock-offs at Bygg-Max.

Best regards, Findus

Why not a couple of shelves instead, those brackets look flimsy!

Here are some options:

It will surely be better and cheaper than your "bookshelf solution".

Regarding the curtain rail: Make sure to screw into the ceiling joists/paneling for sturdiness,
even if some clumsy kid/teen/adult pulls roughly on the curtain.

Hmm, don't even the brackets work if you use 400mm deep instead of 600mm shelves?

Looked at Byggmax system, they don't seem to have hanging rails for their standard system.
Do you attach these directly to the wall then?
https://www.byggmax.se/förvaring/väggskenor-och-konsoler/väggskena-p25781

Do 370mm brackets work for 600mm shelves?

There are larger brackets but not in stock.
Seems like they have really poor stock keeping on these items overall, maybe they are phasing out this system?

Seriously, what do you have against shelves that stand on the floor and are 110% secure?

There are quite a few walls and large areas that I need to cover with shelves.
Having floor-standing shelves everywhere becomes a bit cluttered, I also think it will be more expensive.

Compared to your pine board, it would hardly be more expensive; those metal shelves include the shelves. I have Harald's shelves in the garage and I am very satisfied with them. The connecting plate is a bit too weak, but with some creativity during assembly and anchoring the shelves to the wall and screwing them together, they become very stable.

I have also built with the flimsy bracket from Byggmax and melamine boards in the storage room and I can say that they become very flimsy - it looks better in pictures than in reality Max 400 mm works, 300 mm is preferable. My shelves are in a small room, so I have them well-anchored in the corners/ends, it's acceptable but not more.

Pelly system (many names for a beloved object) also works quite well, but the classic screwed vertical rails are preferable if you want to load them a little. The hanging rails are very fun to install, but that's where the advantages end - it becomes rather rickety. We have hanging rails in the bedroom wardrobe, it works. In the office, we have screwed the rails and installed 270 mm brackets with 300 mm melamine shelves, it turned out really well and withstands some load.

Another fun option is to make your own brackets out of dimensional lumber and thin plywood. It might be a few bucks cheaper but most of all it's so much more fun

600 mm deep shelves probably won't work well in a wall-mounted system, no matter what you choose. It probably needs a floor-standing one.
