10×1-1/4 Sharp Point Torx/Star Screws
This kit provides sharp-point cement board screws designed to fasten cement board to wood. Made from heat-treated steel with ceramic coating, the screws offer corrosion resistance across common backer boards such as Hardiebacker, Wonderboard, and PermaBase. The Torx/Star head (T-25) delivers high torque with reduced cam-out, enabling cleaner installs with fewer driver slips. A one-pound bag includes 166 screws, making it a practical option for mid-size tiling or backer-board projects.
FASTENMASTER Trim Screw 2″ L
These trim screws are optimized to conceal fasteners when installing PVC trim boards. The trim head design minimizes the footprint, offering a clean, concealed appearance. The package includes 75 screws, 100 plugs, and setting tools for a streamlined installation. The star-drive design reduces cam-out, helping protect both the fastener and the bit, while the low-profile cylinder head provides a visually smooth finish on trim work.
Simpson Strong-Tie TSV214R70WH01 PVC Trim-Board Screw
The TSV214R70WH01 features a unique box-shaped cutter head and a triple-thread design for low-torque driving and firm holding. The 6-lobe drive reduces bit cam-outs, extending bit life and simplifying exterior PVC trim installations. With exterior-grade coating, this screw is well-suited to resist weathering when used on exterior trim and board applications, contributing to reliable, long-lasting performance.
Cement Board Self-Drilling Screws, 8 x 1-1/4
These self-drilling cement board screws deliver reliable performance for cement board projects. The #8 diameter and 1-1/4 inch length are well-suited for fastening cement backer boards, providing strong holding power with simple installation. The product is sold in a compatible quantity for typical backer-board projects, and the steel construction offers dependable durability for construction tasks requiring cement board attachment.
Power Pro Gray Ceramic Wafer-Head Screws
These wafer-head cement board screws combine a textured head for improved mortar adhesion with a star-drive for retrofit-proof driving and reduced stripping. The aggressive countersinking blade system preps the head for flush countersinking, enabling tidy installations in cement board projects where a smooth surface is desired. The gray ceramic coating adds corrosion resistance for exterior or damp environments.
Buying Guide
When selecting screws for PVC board projects, consider the following factors to ensure a proper match for your application:
- Material and coating: Choose corrosion-resistant coatings (ceramic, zinc, or polymer) for exterior or humid environments to extend life and reduce rust stains on PVC boards.
- Head and drive type: Torx/star drives reduce cam-out and are easier to drive with power tools; wafer-head or recessed trim heads provide cleaner finishes on PVC trim and backer boards.
- Length and diameter: Ensure the screw length is long enough to engage the core of the substrate without penetrating through the target surface. For cement boards, a typical range is 1/8″ to 1/2″ beyond the board thickness, depending on the substrate.
- Self-drilling capability: For cement board, self-drilling screws simplify installation by cutting into the substrate, reducing pre-drilling steps and time.
- Application suitability: Use trim screws for concealed fastening on PVC trim, and cement-board screws for backer-board installations to maximize holding power and minimize splitting.
- Quantity and packaging: Select a package size that fits the scope of your project to avoid frequent refills and ensure consistent installation quality.
Depth of installation and compatibility with your power tools are critical. If using a drill driver, set the torque to avoid stripping the head or overdriving. For exterior applications, prioritize coatings designed to withstand moisture and temperature fluctuations. In mixed-material builds, select screws described as suitable for both PVC trim and cement board to ensure consistent performance across components.
In summary, the screws listed here offer a range of designs—from self-drilling cement-board screws to trim screws with concealed-head options—catering to common PVC and cement-board projects. Assess your substrate (wood, PVC trim, cement board), environmental exposure, and installation method to determine the ideal screw for your next renovation.
