Product details
Description
The POWERTEC cement screws are engineered for secure, heavy-duty fastening applications across dense masonry materials including concrete, brick, cinder block, and cement backer boards. Manufactured from tough C1022 low-carbon steel, these fasteners feature an advanced high-low thread design that bites aggressively into pre-drilled holes to maximize surface contact and holding power while minimizing drive torque.
Each screw is protected by a durable blue Ruspert anti-corrosion finish, rigorously tested for up to one thousand hours of salt spray resistance, making them ideal for both interior projects and exterior installations in high-moisture areas. The integrated T25 Torx star drive head delivers high torque transfer and eliminates cam-out or stripping issues common with traditional fasteners.
Serrated underhead ribs pull material tight for a clean, flush finish. This comprehensive one hundred fifty pack includes a matching T25 Torx bit with a quarter-inch hex shank, providing an efficient, professional-grade solution for construction, framing, and home improvement projects.
How to use
- Pre-drill a 5/32-inch (4mm) pilot hole into the concrete, brick, or masonry material.
- Align your fixture or cement board over the hole, insert the screw, and drive securely using the included T25 Torx star drive bit until the head sits flush.
