Ok - Potentially silly question. McFeeleys sells screws that are either
Deep thread or Coarse or Fine. What is the difference between a "deep"
vs "coarse" thread? Applications differences? All of the ones I have
bought are "deep" threads and I have been very happy with them. I have
some "deep" thread and "fine" thread Kreg pocket screws and both work
well in hardwoods that I have used to date with no noticeable difference.

Screws made specifically for termite barf are usually deeper in
thread, Brian.

Ok. It looks like "deep" and "coarse" are the same thread type.

Makes sense. How does 'deep' differ from 'coarse'? It's funny, I have
around four FWW articles on screws and they all gloss over thread types.

(duh) Scratch that. I'm still half asleep. I got it.

I thought "deep" had a reduced shank diameter. Overall diameter the the
threads are the same, but because the shank is narrower, the threads are
deeper. Make sense?

Not sure what distinction McFeeley's is trying to make, but generally,
"coarse" and "fine" in relation to screw or bolt threads has to do with
thread count per inch (or put another way, thread pitch.). "Deep" of
course would refer to the depth of the threads, peak to root or valley. So
it would be very possible for instance to have a coarse thread that is
shallow, or a fine thread that is deep.

I think Larry got it right, but I also think coarse threads are
generally both coarse and deep, and fine threads generally fine and
shallow, but I guess it doesn't have to be that way.
I like coarse/deep threads all the time. Fine/shallow threads are shaky
in soft woods like pine, but coarse works in both, so I buy only
coarse/deep.
