Answer: 
An in-store display shows using 1 1/4 for directly mounting on wall studs ,
and 1 5/8 if there's another layer ( eg of greenboard) in between.
But that seems a little shallow to me. you 'd get a little more than 3/4" of penetration. why isn't more better?

Rated 5.0 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 by Easy to start in the board It really helps to speed up the finish time, when you are not fighting the screw where it grabs every time In the board! July 5, 2016
Rated 5.0 out of 5.0 by A new technology screw. This is a new technology screw, not just a regular screw. I love the technology and the brain behind it! It works really well on cement board, and it holds very strongly to the studs; it is nothing like the regular screws. This is the best screw for the cement board so far. April 18, 2016
