TV in Plaster Wall (Expanding Screws Not to Be Used)

[Kaffekoppens]

Hello!

After much nagging from my partner, I have decided to listen and set up the TV yesterday!

The TV is 65 inches with a weight of 22kg. I checked the agreement with the landlord, and it states that you cannot use expander/molly screws as these are completely new apartments, etc., and no screws longer than 30mm!

I borrowed a stud finder to try to mount the bracket in the studs, but when I tried to drill into them, I saw they were metal and not wood as I had hoped. So I tried screwing a wood screw directly into the plasterboard, and after about 10mm, it became tight. I guess there's a wooden board behind! So I put 6 wood screws without plugs directly into the wooden board behind the plasterboard and feel they went in tight at the end, so something must be holding them. Will this work in the long run?!

It's been up for 12 hours now, but it feels like if I slam the door too hard, it will fall down. Am I just worried about my nice OLED, or should I redo it? And how should I do it if so?

Best regards

How many screws and how thick?

If it is not possible to secure adequately in the existing bracket holes, one method is to first screw a plywood sheet with a larger number of screws (say 25 pieces) and then attach it to that.

Edit: If it is a rental apartment, you should be prepared that the landlord may have opinions upon moving out if there are many/large holes in a wall, meaning an extra cost may arise there.

There are 6 screws in total, all lined up! They are 30mm long and 12mm thick. They fit well in the bracket and press it firmly against the wall! Tried pulling on the bracket before the TV was mounted, and nothing moved directly!

If there is a wooden board behind, then there are no problems as long as the screws have tightened, which it sounds like they have done.

There are 6 screws in total, all in a row! They are 30mm long and 12mm thick. In the bracket, they sit well and press it firmly against the wall! I tried pulling the bracket before the TV was mounted and nothing moved noticeably!

12x30 can hardly be the screw, right?
The first 10mm probably don’t hold anything at all when there is a drill tip and the last 12 are in plaster, plus the bracket is probably 2-4 mm too?
So your TV is hanging on a few mm in unknown material...

12x30 can't really be the screw, can it?
The first 10mm probably won't hold anything when it's a drill bit and the last 12 is in plaster, and the mount is probably 2-4 mm too?

First 10mm is plaster then the mount is 2mm so it goes approximately 18mm into the plywood!

3.5 x 30mm**
just noticed I wrote it wrong!

The first 10mm is plaster, then the bracket is 2mm, so it's approximately 18mm it goes into the wooden board!

Picture of the screw?
All the thousands of screws with drill bit tips don't really hold in the tip. At best, you have 8-10mm that actually hold.

Picture of the screw?
All the thousands of screws I've screwed with a drill tip don't pull anything at the tip. At best, you have 8-10mm that pulls something.

Picture of the screw?
All the thousands of screws I've screwed with a drill bit don't grip anything at the tip. At best, you have 8-10mm that grips slightly.

Unfortunately, I am very skeptical.

Possibly if it is an extremely slim mount and a slim TV with no tilt or swivel functions. Then you almost exclusively get vertical load.

If the wall is reinforced for the TV, then you have a stud or plywood/Osb behind it. And in new apartments, it is usually like that and then visible on the plan sketch.

I am also skeptical of this solution, hence the post! They feel like they're holding, considering that it’s almost flush with the wall and weighs

This is the floor plan, the TV is on the same spot! The question is if approximately 10mm into the plywood with 6 screws for 20kg is enough?

I am personally skeptical about this solution, hence the post! It feels like they are holding, considering it is almost against the wall and weighs

This is the floor plan, where the TV is in the same place! The question is whether it's enough with about 10mm into the plywood with 6 screws divided on 20kg?

If all 10mm go in, then I don't think it will fall down.

If you have a wooden board behind (you should see it when you've screwed), then of course no plug or expander is needed. However, you have used the wrong screw.

Get 6x30, for example https://www.hornbach.se/p/grabber-traskruv-c1-5-0x30mm-kullrig-200st-tkz5030/6331706/ but preferably 6mm rather than 5 as I linked to.

4 should be enough for the TV to stay there for the rest of its life.
