I think that my stock H-D spokes have a thread pitch of M4x0.80
At first I thought it was 32 threads per inch but the 10x32 tap and die was too big and the 8x32 was too small. I really don't think there is a 9x32 but there also doesn't seem to be a M4x0.80.
I have a set of spokes from an aluminum 17" rim that I want to use on a steel 17" rim but the spokes are a little too long. They are about 7-3/8"/187mm.
I was hoping to just cut the threads in a little with a die but that isn't looking like a viable option.

 

I think the M in the size is metric. Try some metric thread gages.

 

"Text only" can lead to misunderstandings...but not always confrontational

 

I was able to count the threads. There were 20 threads on the spoke and that measured 16mm. 16 divided by 20 is .80.
There is a M4x0.70 but doesn't seem to be a M4x0.80.

 

Do you happen to know what thread pitch these spokes have?
Is it just an odd ball proprietary thread pitch?

M4.5 x 0.75

Did you just make that up?
I could have been off a thread or two on my count but the major diameter of the threads is 4.30mm. How could that be 4.5?

Or a saboteur.

 

Most good tap and die sets have thread gauges. They will tell you what thread pitch even if you only grab a few threads
