POWERTEC Cement Screws #8 x 1-5/8″, Ruspert Coated Concrete Screws with T25 Torx Star Drive Bit – High-Low Thread Masonry Screws for Cement Board, Concrete & Brick, 150-Pack (72318)

The POWERTEC 72318 Cement Screws are engineered for fast, secure fastening into concrete, cement board, brick, and light-gauge steel studs. Featuring a high-low thread design, these screws increase surface contact for superior holding power while reducing installation torque. The T25 star drive head maximizes bit engagement to prevent cam-out, allowing for smoother driving and better control—especially in dense masonry materials. Built from SAE 1022 low-carbon steel for strength and toughness, each screw is protected with a Blue Ruspert coating tested to 1,000 hours of salt spray resistance for long-lasting corrosion protection in both interior and exterior applications. This 150-pack includes a matching T25 Torx bit with a 1/4″ hex shank, giving you a ready-to-use fastening solution for professional construction, remodeling, and cement board installation projects.

• HIGH-LOW THREAD DESIGN FOR SUPERIOR HOLDING POWER: Engineered with deep high–low threads that bite aggressively into pre-drilled holes, these cement screws maximize surface contact for stronger anchoring in concrete, brick, block, and masonry materials.
• T25 STAR DRIVE FOR MORE TORQUE & ZERO CAM-OUT: Features a T25 Torx head that delivers higher torque transfer and prevents stripping, solving the common issue of slipping found with Phillips or slotted fasteners. Includes a matching T25 1/4" hex shank bit for immediate use.
• RUSPERT COATING FOR EXTREME RUST RESISTANCE: Protected with a durable Ruspert anti-corrosion finish that passes 1000-hour salt spray testing, making these screws ideal for both interior and exterior installations—including high-moisture job sites.
• SERRATED UNDERHEAD RIBS FOR FLUSH, TIGHT SEATING: Designed with serrations beneath the screw head to pull material tight and ensure a clean, flush fit. Perfect for cement board installation, framing over masonry, and light-duty structural applications.
• DURABLE C1022 STEEL FOR CONSISTENT, RELIABLE PERFORMANCE: Manufactured from C1022 low-carbon steel for improved toughness and ductility, reducing breakage during installation. Recommended for use with pre-drilled 5/32" (4mm) holes in concrete or masonry for best results.
