Quick metric imperial conversion
Im having a blonde moment and my trusty zeus book of truths has let me down...
What is 10/32 (unf) in metric? I stoopidly thought it was close to 8mm....so ordered the part, and its waay smaller

10/32 UNF? No such thing - you mean 5/16, which is just under 8mm.
Spin 'er off Well...

Odd. I get 7.9mm too.
25.4 /32 = 0.79
0.79x10= 7.9mm

Hmmmm, I've just found a chart on t'interweb that refers to UNF thread sizes 0-12, then from 1/4" upwards. Have a look
here. After many years working on obsolete machinery I've never come across this before
You're looking at a number 10, 32tpi and an external diameter of approximately 4.5mm.

LOL!!! oops...my mistake.....BUGGER!
I dont think my shiny new 8mm rod ends will fit...
Has anyone seen any rod ends or clevises with such a weird thread?...Or am I going to have to resort to glue and bluetack?..
(its for my BEC gearchange)

Definitely 10-32 NOT 10/32
Its a number "10" size with 32 tpi pitch and is very similar to M5.
The equivalent coarse thread is 10-24

Wouldn't need any persuasion...would be a touch loose if anything...be tight the other way round..
However I could not condone such a bodge...

Shame I dont have a lathe....I wonder if you can turn 8mm threaded rod into 5mm threaded bar using an angry grinder
(Im not seriously going to try it!)

Your local nut and bolt shop can probably sell you the correct nut
