1/4 inch socket, back nuts (black plastic)

Assuming no one knows of a UK supplier of packs of just these and not
sockets plus nuts. I've run out of salvaged ones to replace the missing ones
from amps, to be repaired for other reasons than just missing nuts, but
cannot return to owners with missing ones.

How to make adequate replacements ? any ideas.
The thread for the plastic ones seem to be 12mm x 1.75 pitch, ie coarser
thread than the metal ones that I have dozens/hundreds of.
Find some black plastic of the right sort of thickness. Ignore the flange
bit. Grind a cutting face on all 6 sides of an appropriate size old hex
socket set driver to punch the outer hex shape. Punch a circular central
hole and tap 12mm thread.?
