Thread Type SP2 Steering Stem

can anyone find the type of thread pattern on an SP2 Steering stem? i lost the nut supplied with my Matris Damper and need to have a replacement nut machined. Anyone with a thread gauge know what thread i need for the nut?
Matris hasnt responded to my emails.

Have your machinist measure your stem.
I've made many stems and nuts. That's what I have to do most every time.

Have you tried contacting Scotts and asking them?

If you have a decent metric ruler, just measure the thread pitch.
It'll probably be 1.25 or 1.5mm per thread for such a large fastener.
Once they get above 10mm diameter, they usually jump to 1.5mm/thread for bolts.

Don't ask me why they did this cause they strip out all the time, but the pitch is 1.0 and yes i checked it with a thread pitch gauge.
