S-90031A155 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for long-lasting performance in various environments.
• Superior holding power in wood due to partial threading and thread-forming design that reduces splitting and ensures a tight, secure fit.
• Efficient installation with a Phillips No. 2 drive that minimizes cam-out and allows for consistent, reliable fastening.
• Versatile application compatibility for both hardwood (using 5/64" drill bit) and softwood (using 1/16" drill bit), streamlining project workflows.
• Optimized head design with a standard flat profile that sits flush with surfaces, providing a clean, professional finish.
• Reliable thread engagement featuring right-hand threads and 18 TPI for strong, predictable fastening in wood materials.
• Environmental and regulatory safety by complying with RoHS 3 and REACH standards, ensuring safe use in industrial and consumer projects.

Professional Applications & Engineering Value

These zinc-plated steel wood screws are engineered to address common challenges in woodworking, such as material splitting and weak grip. The thread-forming tapping method creates strong, permanent threads in wood without pre-tapping, reducing installation time and improving holding power. The partially threaded design concentrates grip near the head, minimizing stress on the wood while the flat head ensures a seamless finish. Ideal for furniture assembly, cabinetry, and construction, these No. 6 screws provide reliable performance in both hardwood and softwood applications, supported by precise drill bit recommendations to prevent errors and ensure durability.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.138" and approximately 18 threads per inch, ensuring consistent fit. The flat head profile and Phillips drive comply with common industrial specifications for ease of use. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting environmental safety in manufacturing and usage.
