What is the thread pitch on the single lock adjustable tappet?

How much adjustment does a 60* turn of the adjuster (one flat) make in the lash?

As always, Thanks Fordbarn

On my adjusters, one flat is .007". I had to measure my threads with a thread pitch gauge to determine that.

I believe the .007 is correct. Given that, I never seem to be able to get it right the first time. Always takes a few tries. Hope to see you at Sharon. I'll bring my carb again! Gar
