Answer: 
Yes use it to fasten to floor . You don't need anything else to hold it down, but many prefer to also use thinset mortar to help fill out the gaps and reduce any waviness

Rated 3.3 out of 5 by 11 reviewers.
Rated 3.0 out of 5.0 by Inconsistant Used with Durock backer board and steel studs for an outdoor kitchen. Some screws would not self drill into the steel. Most penetrated the steel with ease. The backer board has to be held tight against the studs or will push out the backer board and elongate the holes. August 2, 2016
Rated 4.0 out of 5.0 by Worked exactly as marketed Purchased a bucket of screws and it behaved as such. July 19, 2016
Rated 1.0 out of 5.0 by Don't waste your money Most of the screws strip out when setting and don't recess into the board. The Phillips tip slips on the screw and strips it. I tried another tip and the screw dulled the tip. I've been doing home improvement for 30 years, not a rookie. I tried a 2.5 inch wood screw and it drove in perfectly. The screw head has a bad design and the tip slips once it hits resistance, thus stripping the head. March 2, 2016
Rated 5.0 out of 5.0 by Novice complaints These screws work just fine for ANY type of cement board, Wonder Board, Perma Base, Durock & Hardi-Board. People complaining don't know what they are doing. Who cares if the heads are up by 1/32 or even 1/16 of an inch in Hardi Board? If you know how to set tile like I've been doing for 20 years that little bit does nothing with the correct amount of thin set under the tiles. The other screws sold that claim to be specifically for Hardi-Board work about the same just have a recessed square head instead of Philips. The Hardi version screws don't sit flush either because the product is just too hard. Lumber yards sell the same screws by a different brand in a box that reads "Cement Board" for pros to use on all products. The difference between both screws this company sells is null and they are different just to help steer amateurs in the right direction. November 7, 2015
Rated 5.0 out of 5.0 by Work Great When Used Correctly We are doing a second floor tile installation and are by no means professionals, but it seems that there is confusion about the backer boards. In the "Wet" area of our bathroom floor we used the Hardy Backer board as recommended to us by our very helpful Home Depot associate and used the "Backer-On" screws with the square heads, which worked perfectly. For our "Dry" area of our bedroom we used the cement board and these "Rock-On" screws and in placing over 1800 screws we had perhaps two that were not going in correctly (and that may have been me). If a woman who has never held a power screwdriver before a year ago can make these work, anyone should be able to. They are a great product, you simply need to use them as instructed (HINT: read what types of board they are designed for)... January 12, 2015
Rated 5.0 out of 5.0 by Why is this so confusing? Why are people using ROCK-ON screws for Hardibacker? They should be using BACKER-ON screws. These particular screws are meant for Wonderboard. These people call themselves "Pros"?? Sounds like they need a bit of re-education. I've been using these screws for over 10 years with no problems. August 19, 2014
Rated 1.0 out of 5.0 by Steer clear of the phillips head version Stick to the square drive head version of these backer screws! You will waste a lot of the phillips head screws and they will not drive flush on Hardibacker 500. I would guess a fifth of the phillips box was at least torn up during installation. Whether they are deep enough (flush to surface) or totally stripped out was just a matter of luck. I went back to the square drive screws with the same great success I had in the past. Do NOT waste your time or money on the phillips head screws. September 13, 2013
Rated 1.0 out of 5.0 by Avoid PHILLPS head and use SQUARE head screws. Almost every other screw is slipping and wont go sub-surface which is a BIG problem for tile installation... Buy square head screws instead of Phillips and you will have one less problem to deal with. February 27, 2014
