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.
