Hillman Fasteners 48890 Cement Board Screws 9x1-5/8 140 Pack

Product Description

The HILLMAN FASTENERS 48890 is a 140-piece pack of #9 x 1-5/8-inch Power Pro cement board screws engineered for fastening cement board to wood framing or light-gauge metal studs. The Type 17 point pierces wood and metal studs ranging from 26 to 20 gauge without predrilling, while the high-low thread design drives cleanly through dense cement board material. An epoxy coating provides corrosion resistance, making these screws suitable for both interior and exterior applications, including use with treated wood. Each package includes a free T20 Pro-Stik driver bit designed for stable one-hand operation. Tile setters, flooring installers, and general contractors rely on these screws for backerboard prep work.

These screws are recommended for use with 1/2-inch cement board fastened to wood or light-gauge metal stud framing. One 140-piece package provides enough screws to install six 3-foot by 5-foot boards. The twist shank design clears debris during driving to reduce the risk of board cracking. The textured head promotes mortar adhesion after installation, making these a practical choice for tile substrate preparation in kitchens, bathrooms, and other wet or high-humidity areas. Compatible with all major cement board brands.
