Thereof, can you screw into hardiplank?
Fasteners must be corrosion resistant, galvanized or stainless steel. Electro-galvanized nails are acceptable for use with James Hardie Siding Products, but may exhibit premature corrosion. James Hardie recommends the use of quality, hot-dipped galvanized nails.
Similarly, can I screw into cement board?
Cement board attached to plywood or similar underlayment will hold with only 1 1/4-inch screws; for thick or heavy metal fixtures, use 1 5/8-inch screws. In general, 1 1/2-inch galvanized nails will hold the board firmly in place. Even if you use this extra adhesive, you should still apply the nails or screws.
Avoid fastening in a straight line. Fasten HardieBacker boards with proper fasteners (as listed in “Materials Required”) a maximum of 3 in on center around the perimeter and 6 in on center in the field. Keep fasteners between 3/8 in and 3/4 in from board edges and 2 in in from board corners.
