strange bearing preload threads on ball screw

[mxpro32]

I have a problem that i haven't yet solved. My ball screw has bearing preload threads that are 10mm x .8 pitch. As far as i can find the only threads that come in a .8 pitch are 5mm. I know the threads are .8 because i checked them with a pitch guage. If anyone has any information to help me i would really appreciate it. thanks.

Seams you will need a special kind of nut for this.
Check with the manufacturer.
Good Luck
