Product Description
Ideal-Length Cement Screws for Backer Board & Light Masonry Work
The POWERTEC 72319 Cement Screws are purpose-built for cement board installation, thin-set masonry fastening, and light-duty concrete applications. At 1-1/4" long, these screws provide the perfect length for securing backer board over studs or attaching materials to concrete without over-penetration. The high-low thread design and T25 star drive head deliver the same professional-grade performance you'd expect from longer masonry screws—just sized right for jobs where you don't need extra depth.
This 200-pack gives you more screws per box for bigger cement board projects, and includes a matching T25 Torx bit so you're ready to work the moment you open the package. The Blue Ruspert coating provides 1,000 hours of salt spray resistance, making these screws equally reliable for bathroom backer board, basement moisture barriers, or exterior cement panel installations. If you're tired of overdriving screws or dealing with excess length on tile prep jobs, this is the fastener you've been looking for.
Key Features & Benefits
High-Low Thread Design for Superior Holding Power
- Aggressive bite into pre-drilled holes: Deep high-low threads create more surface contact than standard concrete screws, giving you stronger pull-out resistance even in softer masonry substrates
- Lower driving torque for easier installation: The thread geometry cuts through material smoothly, reducing stress on your drill and making repetitive fastening less fatiguing on large backer board jobs
T25 Star Drive Eliminates Cam-Out & Stripping
- No more slipping or stripped heads: The T25 Torx drive maintains positive engagement throughout the entire drive cycle—critical when you're setting dozens of screws in cement board over a full bathroom or basement
- Includes matching T25 bit with 1/4" hex shank: Works with impact drivers, drills, and screw guns, giving you a complete fastening solution right out of the box
Ruspert Anti-Corrosion Coating for Indoor & Outdoor Use
- 1,000-hour salt spray tested: The Blue Ruspert finish resists rust and corrosion in high-moisture environments—ideal for shower surrounds, basement installations, and exterior cement panels
- Long-lasting protection: Keeps the C1022 steel core protected year after year, even in damp conditions where standard screws would corrode
Serrated Underhead for Flush, Tight Seating
- Pulls backer board tight against framing: Serrated ribs beneath the screw head grip material and draw it flush to the substrate—no countersinking needed for a clean, professional finish
- Perfect 1-1/4" length for cement board over studs: Provides secure fastening without over-penetration, reducing the risk of cracking board edges or hitting plumbing/electrical behind the wall
Durable C1022 Steel Construction
- Improved toughness and ductility: Low-carbon steel construction resists breakage during installation—especially important when driving multiple screws in quick succession with an impact driver
- Pre-drill for best results: Use a 5/32" (4mm) masonry bit for pilot holes in concrete or brick, then drive screws smoothly and securely with minimal effort
