S-91550A304 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Superior Corrosion Resistance: Zinc-plated steel construction provides excellent protection against rust and environmental exposure, ensuring long-term durability in various woodworking applications.
• Enhanced Holding Power: Thread-forming tapping method creates strong, permanent threads in materials like plywood and OSB, reducing the risk of pull-out and loosening over time.
• Versatile Drive Compatibility: Combined Phillips/Square drive head allows for flexible tool selection, minimizing cam-out and improving installation efficiency with both common driver types.
• Optimal Countersinking: Standard flat head with 90° countersink angle sits flush with the material surface, creating a clean finish and preventing snagging in woodworking projects.
• Full-Length Threading: Completely threaded shank maximizes grip and distribution of clamping force along the entire screw length, providing superior fastening strength in wood substrates.
• Precision Engineering: Consistent 0.138" thread diameter with 18 TPI ensures reliable performance and compatibility with standard 1/16" pilot holes for easy, accurate installation.
• Environmental Compliance: RoHS 3 (2015/863/EU) compliant manufacturing ensures safe, environmentally responsible production without restricted hazardous substances.

Professional Applications & Engineering Value

These No. 6 wood screws are specifically engineered to address common fastening challenges in plywood and OSB applications. The zinc-plated steel material provides essential corrosion protection for both interior and exterior woodworking projects, while the thread-forming technology eliminates the need for separate tapping operations in composite wood materials. The combination of Phillips/Square drive compatibility offers contractors flexibility in tool selection, reducing installation time and preventing driver slippage that can damage screw heads. The fully threaded design ensures maximum holding power across the entire fastener length, crucial for maintaining structural integrity in cabinetry, furniture assembly, and construction applications where vibration resistance is paramount.
