TV on OSB

[Raka]

Moderate.

Approximately 40mm protrusion from the bracket, and check that there are threads where the OSB is located. That is, so there isn't a smooth part where it can attach. For example, I can imagine that fully threaded 6x40-50 are moderate.

They can handle about 20-25kg/screw when they are in OSB.

Where can you find 6x40-50mm screws? The building stores I've been to only have 6x60mm as the shortest. Should work just as well? Worried about puncturing the vapor barrier but you do that with shorter screws as well, and the small holes that result don't really matter, do they?

Drive 5 mm.

Isn't it possible that the appropriate screws and washers came with the mount?

 

[Raka]

Isn't it as simple as suitable screws and washers came with the mount?

Sturdy French screws were included. Should I go down to 5mm and take 40mm length?

Tex Hornbach has 6x40 on the shelf for Grabber wood screws. I also think it's available in bulk.

It will probably be fine. Add an extra one if you're unsure.

Also, check that the head of the screw isn't too small in relation to the holes on the bracket. If so, you'll need to add suitable washers.

These are expensive and nice, but in your case, you can use anything; it will hold well anyway.

French screw is probably not threaded all the way up to the "head," so it might be a slightly worse choice.

 

[MathiasS]

I have thrown away the French ones I had. Worthless compared to modern alternatives. I use VSB's jetting screw with a hex head instead:

There is also a very similar screw at Biltema which is also good, I think it's actually a vsb-screw as well.

These ones? https://www.biltema.se/bygg/fastelement/traskruvar/traskruv-hex-2000038518

You should have a screw that is threaded all the way up to the head, if the threads end so far back that they are behind the OSB, they are of little use. Like this https://www.ahlsell.se/10/infastning/byggplatskruv/byggskruv/4443593/

 

[MathiasS]

These? [link]

Yes, that is good, but you must make sure you have threads where you have osb.

 

[tlundberg]

but as I said, you must make sure that you have threads where you have OSB.

Of course But I have about 25 mm to the OSB, so it should work. And we are talking about it holding 170 kg per screw? In my case, I'm thinking of hanging a hanging chair from the ceiling. So it has to hold for a 100 kg man sitting down a bit heavily... The ceiling mount has two screw holes.

Unfortunately, I don't know anyone who can shop for me at Ahlsells. I also don't have a Hornbach nearby (as was suggested earlier in the thread). Biltema, Jula, Jem&Fix, Beijers, Tools, and Byggmax are pretty much what I have to choose from...

 

[elmont]

I am convinced that Beijers has them, but I don't know what name they have for them, maybe konsolskruv or staps or byggplåtskruv or... a beloved child has many names.

 

[tlundberg]

This one maybe https://www.beijerbygg.se/privat/sv...yggskruv-6-5x75-med-fläns-fzb-100st-001377640
But it feels a bit steep with 600 SEK for the two screws needed for a roof mount...
