S-91070A112 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various environmental conditions.
• Enhanced installation versatility through dual Phillips/Square drive options, reducing tool slippage and speeding up assembly processes.
• Maximum holding power in wood materials thanks to thread-forming technology that creates strong, secure threads without pre-tapping.
• Full-length threading for complete penetration, providing consistent grip and reducing the risk of material splitting in plywood and OSB.
• Precision-compatible drilling with recommended 5/64" drill bit size, ensuring accurate pilot holes for reliable fastening.
• Durable pan head design offering a low-profile, rounded finish that sits flush and resists stripping during torque application.
• Compliance with environmental standards via RoHS 3, making these screws safe for use in regulated industries and sustainable projects.

Professional Applications & Engineering Value

These No. 8 wood screws are engineered to address common challenges in woodworking and construction, such as material splitting and weak thread engagement. Made from zinc-plated steel, they resist rust and corrosion, extending service life in humid or outdoor settings. The thread-forming design eliminates the need for separate tapping, creating tight, durable threads in plywood and OSB that prevent loosening under vibration. With a Phillips/Square drive, installers benefit from reduced cam-out and faster driving, while the fully threaded shank ensures uniform stress distribution. Ideal for framing, cabinetry, and structural applications, these screws deliver reliable performance where high-strength fastening is critical.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.164" and approximately 15 threads per inch, ensuring precise fit. The right-hand thread and pointed tip facilitate easy insertion. Manufactured to common industrial tolerances for wood screws, these fasteners are RoHS 3 (2015/863/EU) compliant, confirming they are free of hazardous substances and suitable for global supply chains requiring environmental safety.
