Due to an offset between the plumbing and the shower drain I need to float the wall on the short side of the shower base with like 3/4-1/2" so I am using top to bottom shims I am not sure if the screws that I have (1-1/4" Durock screws https://www.homedepot.ca/product/cg...k-cement-board-1-1-4-in-200-screws/1001341803 ) fit the purpose.
Can I still use then ? (they will be 1/2" in cement board, 3/8" in the shim and 3/8" in the stud
Just to play safe I bought these screws that are from a different manufacturer

not sure if I can still use them with USG Durock cement boards
It seems that for both it is essential to have a larger head, coarse thread, resistant to corrosion and sharp enough to penetrate the cement board which is stronger than the dry wall
