My wiper motor is missing the securing nut (actually it was missing a few things, but I've managed to make one goodun from bits and pieces).
I've been informed that the nut is 14mm across flats (can anyone else confirm that?), I've measured the thread pitch which is very fine 0.75mm at M10. The spares suppliers want a few bob for new nuts, and they only seem to be available from Germany, so I thought I'd machine my own, but from stainless steel, so they'll stay rust free. I've ordered some HSS taps, just need to get some hexagonal bar to machine them from.
Anyone else interested in these? Can make a few an knock them out for a couple of quid.
