About This Product
Backer-On Rock-On 1-1/4 in. cement board screws (750-pack) offer a reliable, high-performance solution for securing cement boards. Designed with a patented serrated head, these screws ensure flush seating at any angle-creating a smooth surface ideal for tile applications. The star drive recess paired with the Stikfit? bit enables one-handed installation and helps eliminate cam-outs.
Built for durability in high-moisture environments such as bathrooms and kitchens, these screws feature a premium corrosion-resistant coating that prevents rust stains from leaching into grout. Their sharp point and serrated thread design reduce installation time and eliminate the need for pre-drilling.
