I had another look at the starter button thread today and am tempted to think that it is actually an M25 x 1,0mm thread. This is not the standard M25 thread pitch (1.5mm), but a finer pitch one.
I can find M25 x 1.5mm panel nuts on the internet fairly easily. Bearing in mind that they are either brass or plastic (brass would be preferably as it is less "bulky") and that the starter button housing thread is pressed (thin) steel ...
- 1. Would an M25 x 1,5mm panel nut be OK-ish for what I need, or
2. Would I be better to get an M25 x 1.5mm panel nut and an M25 x 1.0mm tap and re-thread the nut, or
3. Would I be better to get an M25 x 1.5mm panel nut and an M20 x 1.0mm tap and re-thread the nut (this would eat into more metal and may give a better result).
Not sure how successful the re-tapping process would be, as I don't know how easy it would be to hold the nut firmly enough without damaging it ...
As a temporary measure I have reduced the thickness of a plastic plumbing nut and painted it silver; the thread pitch is not right & it looks a bit naff, but it'll do for now.
Oh! for an easy life!!!
Any comments?
