In metric thread designation, the second part defines the pitch - in
this case 1.5mm. Standard M14 is 2mm pitch, and there are fine pitch
versions of 1.25mm (metric spark plug) and 1.5mm. The likelyhood is that
you have standard M4 nuts with 2mm pitch. I can imagine that fine
pitch nuts might be hard to find. Maybe someone at Kilovac might be
generous with a couple?
The 6g bit on the end refers to the tolerance on the thread (slack vs
tight fit), I don't have detail of the different classes to hand.
