ᐅ Looking for coarse-thread wood screws with flat heads for a loft bed

Hello everyone,

I am looking for screws for a loft bed (see photos).

They are coarse-thread wood screws with a flat head and internal hex drive.

The sizes are M6x110 and M6x50.

So far, I haven’t found anything like this online or in stores.

Does anyone know where I can source these?

Thanks and best regards
