Hi,

does anyone know the metric screw thread for the lock nut that clamps the top yoke to the lower yoke column?  I think it is metric fine or extra fine but am struggling to find a half nut for it, it definitely is not coarse.

Many thanks

If you have got it, why can't you measure the pitch?

 

Hi,

i thought I would ask as I bet someone on here knows before resorting to ordering a thread gauge as plan 'B'....   ;o)

Measure 10 pitches with a mm rule and divide by 10 to get mm pitch

Hi Feetup,  top tip !  Many thanks  ;o)
