Which screw is this

[stigarn]

I am missing screws for a Sultan box spring from Ikea. These are for the legs that need to be screwed on. Ikea no longer had these as spare parts but could only provide me with the measurements 0.70x40. I have found a picture on the internet that I am attaching. It is also the washers that are missing. Does anyone have an idea of what I need and where I can easily find it?

At a "Bultbar" at any major hardware store?

M4 bolt is 0.7cm in diameter. So maybe M4 40mm?

M4, as the name suggests, is 4 mm in diameter, with a thread pitch of 0.7 mm.
The screws in the picture are thicker, I would say M8 or equivalent UNC thread.

I agree.
Looks like M8..
13 mm wrench.

For a while, they inexplicably had tumgänga on those. Buy an M8 and check that it fits in the mattress frame.

Aren't there pre-drilled holes in the bed frame?
Then it's just a matter of measuring the diameter and length.

The picture shows completely unsuitable bolts for the purpose (too small bearing surface), so either suitable carriage bolts or large washers for ordinary screws. However, carriage bolts only work with a loose nut on the other side.

There are pre-drilled holes in the bed frame, right?
Then you just need to measure the diameter and length.

There's a rampamuff in the frame. Inch or mm.

Does it? There have probably been bed frames both with and without threads, right? I have at least had IKEA (and other) bed frames with just drilled holes. However, the latest Hilding Anders I threw out last week was threaded.

The image shows bolts with metal threads. They should definitely not be screwed directly into the wood. There should be a nut somewhere. Often, it is a t-nut that is used.

To complicate matters, for some reason these often have inch-threads. So M-threads won't work. I think the threads in the image look too coarse to be M-threads.

Thank you for all the answers. Here are pictures of the actual hole in the bed. There is a thread further down in the hole but you can't reach the other side so it must be inserted into the existing thread.

I am missing screws for a sultan spring base from Ikea. It's for attaching the legs. Ikea no longer had these as spare parts and could only give me the dimensions 0.70x40. I have found a picture on the internet that I attach. It's also the washers you see that are missing. Does anyone have an idea what I should get and where I can find it most easily?

Which one did you get??? I have the same problem actually..

I never managed to, so we left it as it was.
