9 x 2-1/2 in. GRK Rt Composite Trim-Head Stainless-Steel Screws - Qty:365

GRK Rt Composite Trim-Head Screws feature a small, low-profile head designed for fine trim applications where a clean, finished appearance is important. These 9 x 2-1/2 in. stainless-steel screws are well suited for composite decking, trim casings, moldings, and other exterior projects where corrosion resistance is a priority.

The stainless-steel construction provides excellent corrosion resistance and makes these fasteners a practical choice for wet environments and applications near oceans or saltwater. GRK's specialized thread and point designs help improve driving performance while reducing the risk of material damage during installation.

Features and Benefits

• Stainless-steel construction: Provides corrosion resistance for demanding exterior, wet, and oceanside environments.
• Small trim head: Creates a clean, low-profile appearance for decking, trim, casings, and molding applications.
• Reverse threading: Threads near the fastener head help reduce bulging on the board surface as the screw is seated.
• W-Cut self-tapping threads: Designed to help prevent splitting in most materials while providing efficient thread engagement.
• Zip-Tip™ point: Helps the screw start easily for smoother, more efficient driving.
• Large quantity: Includes 365 screws for larger decking, trim, and exterior installation projects.

Installation Recommendations

• Drive trim screws at approximately half speed for better control during installation.
• Avoid overdriving the fastener. Backing out an overdriven screw can cause bulging on the surface of the board.
• For controlled installation, use a driver drill with adjustable torque settings or a driver bit equipped with a depth stop.
• An impact driver is not recommended, as excessive driving force can increase the risk of overdriving and may shorten drive-bit life.
• Pilot holes are generally only necessary when required by the building-material manufacturer. Always consult the material manufacturer's installation instructions before fastening.

Ideal Applications

GRK Rt Composite Trim-Head Screws are designed for applications requiring a discreet fastener head and dependable corrosion resistance. They are an excellent choice for composite decking, exterior trim, casings, moldings, and other fine-finish wood or composite projects where proper installation and a clean appearance are important.
