Anybody know what the pitch of the threads are on the bolt shroud?

I do not know off the top of my head what the thread size or pitch is on a Mauser bolt sleeve.
Anytime I had a bolt body that was kind of rough or tight , I put some grinding compound or polish on my Bolt Heat Sink threads and worked it in and out a few times.
It smoothed things up really easily.
I also had to Lap some bolt sleeves in the bolt body to smooth things out also.
