Store SKU # 717202

The Backer-On #10 x 1-1/4 in. Zinc-Plated Steel Flat-Head Backer-On screws are designed for attaching HardiBacker fiber cement backerboard to wood or light gauge steel studs. Ideal for use in high moisture areas such as baths & showers, sink backsplash, countertops and floors. Backer-On's self-drilling point eliminates the need to pre-drill, and a special patented thread design reduces installation torque and provides superior holding power. Special rib design under the head countersinks for flush seating in board, providing a smooth surface for tile. Backer-On screws feature a corrosion resistant finish which prevents rust from bleeding into tile. Backer-On screws conform to ANSI A108.11 for cement board attachment and install with a standard screwgun and a #2 square drive bit (included with product).

CUSTOMER REVIEWS

Rated 3.5 out of 5 by 6 reviewers.
Rated 5 out of 5 by hardie Backer on screws I have used these on several jobs and have had nothing but good results. With an impact driver I have found that they do indeed pull the backer board flush with either floor joists or wall studs. In my uses the bit tends to last about 1200 screws before it breaks. The floors I have re-done (due to the "pros" using roofing nails instead of screws) no longer have that "crunching" noise when walked on. November 10, 2014
Rated 4 out of 5 by decent screws Using an impact driver makes putting these screws in go much easier than a regular drill. Some of the heads were deformed on these and had to trash them, but all in all they were a great buy. Have only had the tile in for about 6 months now, so not sure how they will do over time but so far so good. August 17, 2013
Rated 1 out of 5 by Won't screw flush, breaks hardiebacker at corners, won't pin hardiebacker to studs Just got through replacing all the hardiebacker screws with GRKs multi-purpose screws. The GRKs went in far easier, actually pinned down the board which was 1/4 to 1/8 inch off the studs due to the hardie screws. I thought I noticed the hardie screws pushing out the board when I was nearly spraining my wrist trying to drill them in. I ended up using just 1 hardie screw to just initially drill into the board and then using the GRKs which went in easy, pinned the board to the wall, and countersank easily. July 11, 2014
Rated 2 out of 5 by HardiBacker Screws not so good I have experienced exactly what others on the boards have; the screws separate from the board and are not always flush. I just removed some screws from a tile job done a couple of years ago in a bathroom and to my dismay the screws were already rusted on the outside badly. So back to the drawing board for Hardi, because I am not convinced that they wont rust. Best-Stainless steel September 27, 2012
Rated 5 out of 5 by Great screws Anybody who cant screw in these screws should not be using them. I am a professional contractor and have no problem screwing them in with an impact driver. Hardibacker can split if you drive a screw to close to the edge, but that has nothing to do with the screw. September 6, 2014
