S-90031A566 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Superior holding power with thread forming design that creates strong, permanent threads in wood without pre-tapping
• Reduced wood splitting through partial threading that minimizes stress concentration in delicate wood materials
• Enhanced corrosion resistance with black-oxide steel coating providing durable protection in various environments
• Secure installation with Phillips No. 2 drive that prevents cam-out and ensures consistent torque application
• Clean finish appearance with standard 82° flat head profile that sits flush with wood surfaces
• Versatile material compatibility with specific pilot hole recommendations for both hardwood and softwood applications
• Reliable performance with precise No. 8 screw size and 15 threads per inch for consistent fastening results

Professional Applications & Engineering Value

These No. 8 wood screws with black-oxide steel construction and thread forming technology address critical challenges in wood fastening applications. The partially threaded design significantly reduces the risk of wood splitting, particularly in delicate hardwoods and softwoods, while the thread forming action creates superior holding power without the need for pre-tapped holes. The Phillips flat head configuration with 82° countersink angle ensures flush mounting for professional finishes in furniture manufacturing, cabinetry, and construction projects. The combination of 0.164" thread diameter and 15 threads per inch provides optimal balance between pull-out resistance and installation efficiency, making these screws ideal for both production environments and custom woodworking applications where reliability and appearance are paramount.
