#10 x 2-1/4 Cement Board Star-Drive Screws T-25 Torx Head - Reliable

In this review the focus is on a full box of #10 x 2-1/4 in cement board screws that promise a reliable way to fasten cement backer board to wood. The bottom line: these screws are for installers and DIYers who need a durable, corrosion resistant fastener that starts quickly and sits flush. The reviewer found the sharp point and ceramic coating especially useful when working with common cement boards like Hardiebacker and Wonderboard, and the T-25 Torx head reduced cam-out compared with Phillips or slotted heads.

Key Features

• Sharp Point: The sharp screw point allows quick starts into wood backers without pre-drilling, saving time on repetitive installations.
• T-25 Torx Head: The star-drive T-25 bit minimizes slipping and helps maintain consistent torque for cleaner, faster drives.
• Ceramic Coating: The corrosion resistant ceramic finish protects the screws in moist environments commonly found behind tile and cement board.
• Cutting Nibs Under Head: The cutting nibs help countersink the head cleanly so the screw sits flush with the board surface for a smooth tile substrate.
• High-Quality Heat Treated Steel: Heat treated construction provides strength so screws resist snapping during installation and hold backer board securely.

Who It's For

These cement board screws are best for professional tile installers, carpenters, and serious DIYers who frequently install cement backer boards over wood framing and need bulk quantities for large jobs. The full box count appeals to contractors and anyone tackling whole-room applications where consistent performance and corrosion resistance matter.

Less suitable are users who only need a few fasteners for occasional repairs or those fastening cement board to metal framing, where a different point or self-tapping metalthread screw may be preferable. This product is optimized for wood substrates and backer boards.

Pros & Cons

Pros

• Sharp point starts quickly without walking, reducing the need for pilot holes on wood.
• Ceramic coated finish offers corrosion resistance for longevity in damp tile installations.
• T-25 Torx head reduces stripping and speeds repetitive driving.
• Cutting nibs countersink the head cleanly for a flush finish under tile.

Cons

• Sold in a large full box of 2000, which is unnecessary quantity for small projects.
• Designed for wood backing; it is not intended as the best choice for metal studs without a different thread design.
