Steering yoke nut gps mount

[jtopiso_imp]

Hello brothers, sorry I've been quiet on the posting front, I've been spending a lot of time in the saddle. I picked up a ram mount for the steering nut on the top of the yoke and I've been having a heck of a time finding an open nut replacement for it. I don't want to send it back for the handler bar mount since I prefer the minimalist look. Does anyone know the thread size of the nut or any other bike that shares the same size? I know it's a 32mm outside and it's torqued to 75ftlbs. I'm really eager to put my old phone to good use as an offline gps for the long wandering rides. I can provide pics if needed. Any help is greatly appreciated!

It will be a metric thread, so it's easy to measure.

Measured OD will be sligthly under the nominal thread size. So if you get 29.8 on a bolt, you are talking about M30.

Regarding pitch, in metric threads it's just the distance between two consecutive crests (or two consecutive valleys). Or measure the length to cover 10 threads and divide by 10 to get the pitch.

It's probably a standard thin thread, so I guess the pitch will be 1.5 or 2.

So you are looking at M30x1.5 or M30x2.

You can use bolts as "thread gauge": M10 bolt as a thread gauge for pitch 1.5, and M14 for pitch 2.
