Resurecting an old thread again.

Can anyone tell me what the pitch of the thread is for nuts on the replacement ARP studs?

Often is the case that when studs are used to hold down a cylinder head a finer pitch is used for the nuts.

If that is so then what torque figure is applied for the Dato as a finer pitch would result in greater clamping force for the same torque on the nut as compared to the bolt.

Any thoughts?
