I'm after a couple of nuts for my roca wiper motor.

the thickness of the shaft is 16mm or 5/8"

and i have measure the tpi at 28 in 1"

does anyone know what thread it would be as i cannot find a nut for it anywhere

thanks

Local to The Broads ASAP Supplies in Beccles are Roca distributors.  I am sure they will help you out. Their Tel. No. 01502.716993.

I know they were taken over but I am pretty certain they are still on the Industrial Estate.

5/8" unf is 18 tpi, 28 isn`t a typo is it?

UNF do  a 28tpi   so im guessing ita a 5/8unf

[Stranger]

it will make it a large spanner fitting tho  15/16  or 24 mm at a push

28tpi taps are available on ebay for 6 quid if you want to make a nut

asap won't sell just the nuts i don't think, 

yes they are still on the industrial estate

nope 28 tpi isn't a typo it's a very fine thread

did speak to someone who had a 5/8" unf but it wasn't 28 tpi

that is an idea Stranger i'll have a look

i did think could i re-tap the thread to accomadate a more common nut also
