Hi,
Can anyone tell me what is the correct thread for the diver's footrest spindle nut for a WM20?
I lost one and cannot find this info..

Thanks,
Noam.

If my memory serves me correctly they are 1/2"x26 cycle thread...but there is a slim chance they are 1/2"x20 cycle thread. If you have a 1/2" UNF nut lying about you could try that. At 1/2" UNF is also 20 tpi and you would soon deduce if that is correct!...Ian

Hi Noam,

I'm drawing parts on Autocad (semi retired engineer)and really need something to do.

The nut is 1/2 - 20 TPI BSCY (CEI). (60 degree included angle)

Thank you very much Ian and Robb!

by the way, I did not check it, but I was told it should be the same thread as flywheel, timing side?...

These nuts are easy to get, Nooky's nuts sells them and they have good quality nuts and bolts of which many are a good fit on an M20. Also reduced head sizes as fitted on the M20 are available at Nooky's. We always buy a few bags of nuts when we see them at an auto-jumble like Stafford.
