Attaching rails for brackets in drywall?

[A-Man_08]

I'm planning to put up shelves in the basement, it's one of those classic ones with 2 tracks where you click in the brackets.

I'm thinking of doing it simply and cheaply since I have a lot of wood screws.

Shouldn't it work if I take 2 pieces of 28x70 studs, place them on the concrete, and then fasten them into the drywall with 2-3 screws each to hold them in place? The studs will stand on the ground, so they should take most of the force?

There is outward traction at the top. So no, the concrete doesn't take most of the force.

But with glue and plugs, it should still hold. With the right plug, you don't need a board at all. Or place two boards horizontally between the wall and the rails where the screw holes are; it will be maximally strong.

Since I have to use molly to get it right, I might as well go for it and attach the rail directly to the plaster, although it takes 10 of them.

Set the studs, or even regular 21mm boards for that matter, horizontally and screw into the studs so you can place the brackets wherever you want and screw them into the boards.

I still need the rails, in order to attach the brackets, they are the kind that click in.

I bought molly at Wurth and pliers and everything, and discovered by chance today that they've put plywood behind, seems to be 13 mm. Will it be durable with a 5 mm wood screw or should one use 6 mm? It takes 6 screws per wall rail.

Is there any benefit to pre-drilling or is it just a matter of driving it into the drywall?

Or should one use some kind of board plug for double board, molly or something else?

Just screw directly if you have plywood behind the drywall.
I believe it is 5 mm screws that are commonly used. The screw heads on 6 mm are usually too large for the countersinks in the tracks.
It was a while ago since I mounted elfa.

Then I'll go with 5mm, that will definitely hold.
