Description

Rock-On screws are ideal if you are looking for an efficient fastening of cement boards (Hardie-Backer, Durock(R) or WonderBoard) and wood or lightweight steel studs. They feature a flat head with serrated contour for a firm, flush seating, which ensures a smooth, straight surface when installing tiling. The serrated thread and their sharp point allow quick installation and immediate pick up. Installation can be done with one hand using a drill/driver or a standard impact wrench, and the StikFit star drive featuring 6 points of contact (included). Each box contains 185 #9 x 1 1/4" screws.

Rock-On Concrete Screws - #9 x 1 1/4" FH - Steel - 185/Box is rated 5.0 out of 5 by 29.
Rated 5 out of 5 by from Worked Great [This review was collected as part of a promotion.] Used these on Durock board for shower walls. No issues driving them in or getting them flush, and the coating on the fasteners seemed very durable. Lowe's was the only one-stop-shop in my small town that had these items, so whether it applies to you or not it was very convenient for me. The included bit is always a nice touch for the Torx head fasteners.

Rated 5 out of 5 by from Good Screws [This review was collected as part of a promotion.] Used these screws for securing 1/4” cement board with thinset to the subfloor. Excellent holding power. Used a screw every 8 square inches on a 3x5 sheet. Not one screw failed. The screws counter sink very nicely into the cement board. These screws are worth every penny.

Rated 5 out of 5 by from Great product [This review was collected as part of a promotion.] Screws grab just nicely, no slip, hassles. Would definitely us these again instead of the square bit screws.

Rated 5 out of 5 by from [This review was collected as part of a promotion.] These screws are an improvement over the older model. The head of these screws are made with “ “teeth” that allows the screws to better bury themselves into the cement board. They end up flush with the surface providing a level surface for installation of tile.

Rated 5 out of 5 by from Rock on screws for durock [This review was collected as part of a promotion.] Screws worked very well. I liked that it came with a special bit which is better than any philps head screw. Worked well for me to enclose around a bathtub.

Rated 5 out of 5 by from Great with HardieBacker [This review was collected as part of a promotion.] I watched a YouTube video on how to install HardieBacker on my laundry room floor prior to laying tile. The Rock-On screws were perfect for the job. The star bit was included in the package. With just a little pressure the screw grabbed and was easily driven through the HardieBacker and into the floor.

Rated 4 out of 5 by from Great Durrock Screws [This review was collected as part of a promotion.] These Screws worked great to fasten sheets of durrock to 2x4 wood studs for our new shower. Only complaint is that i wish more came in a carton. It took to cartons to screw off my shower surround which was approx 3ftx3ft shower.
