Wiper spindle nuts


Recommended Posts

Thanks to need4speed for donating me his washers :)

I tried to get the thread gauge on the spindle, but the way mine is, the wipers would have to come off to get an accurate measurement. It seemed to be around M8/M10 x 1mm, which would make it a fine thread. TBC

Thanks also landroversforever, I may also go for stainless nuts as well after your lead

After 3.5 years i'm bringing this back up as i've got a separate genuine wheelbox that I measured and it was too hard whilst still on the car...

OD of the thread is 15.4mm. 0.9mm on the thread gauge is too small but 1mm is too large.

I don't have an imperial thread gauge. Any clues anyone can suggest about what the thread might be?

So to wrap up my monologue, the nut is equivalent to 17H8769 from a Mini and other British classics. They're not identical as they come in chrome, but meh 🤷‍♂️. They're eight sided which makes them quite unique and I hadn't noticed before.

Genuine on the left, Mini on the right

Sounds like it would be about 26 TPI then, which is very a fine pitch for the diameter.

I had been going to suggest 5/8" UNF until I read the pitch. UNF for that diameter would be 18 TPI.

 

 

Well whaddya know.... turns out 5/8 " x 26 TPI is British Standard Cycle thread or British Standard Brass (different thread angles on these two).... old as houses.....and Landrovers...
