Details:
In the moden day the internet has yet again failed to find a item I know is out there. I am trying to put up a speaker hanging from a bracket under the shelf NOT the wall 8" away or resting on the shelf. I am looking for the M6 lugs with wing nuts with 2 flats 4mm across so the thread is unable to turn whilr the nut is tightened.
Any idea what they are and where I can order two (or 10ish if needed)?
