I'm building a bed and the legs have these recessed in them so you can screw a bolt into the leg to hold it on.  I've used Google image search and it comes up with a lot of things that look similar but not the actual fitting.

I don't recall seeing these anywhere so I'm hoping that somebody knows what they are and where to obtain them.

I'm making a copy of the drommen bed.
