I recently had to remove the windscreen wiper arms off my wife's Renault Zoe ZE40, and I noticed that the nuts didn't have their protective covers - I think that mechanics often 'lose' them during services as they can be a pain to remove.
I designed my own replacements as the M10 flanged nuts are a non-standard dimension across the flats.
Knowing what major manufacturers are like, these may fit many other Renault wiper arm nuts...
You will need to use a slightly flexible material such as TPU to get a degree of 'grip' on the nut.
