I looked for a screw to connect something to my multiboard with 8mm offset and fit against the wall behind to provide better stability to my multiboard. Based on my model (hole for the big threads but only 1mm thick to be as near at the board as possible) I remixed the 20mm  thread from multiboard to match my requirements.

I take the push fit hole version becasue i can you a standard multiboard hook to tighten it.
