S-90031A520 Length 3" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for long-lasting performance in various environmental conditions
• Enhanced driving efficiency with Phillips drive design that prevents cam-out and provides secure tool engagement
• Optimal flush mounting thanks to the standard flat head profile with 82° countersink angle for clean, professional finishes
• Reduced splitting risk through partial threading that maintains shank strength while providing excellent holding power
• Simplified installation with thread-forming design that creates strong, permanent threads in wood without pre-tapping
• Versatile material compatibility with specific drill bit recommendations for both hardwood (7/32") and softwood (3/16") applications
• Reliable right-hand threading with 7 threads per inch ensuring secure fastening and consistent performance

Professional Applications & Engineering Value

These No. 24 zinc-plated steel wood screws are engineered to address common challenges in wood fastening applications. The thread-forming tapping method creates permanent, high-strength threads in wood substrates, eliminating the need for separate tapping operations and reducing installation time. The partially threaded design provides superior pull-out resistance while minimizing wood splitting, making them ideal for demanding applications in both hardwood and softwood materials. The Phillips flat head configuration ensures flush mounting with standard 82° countersink angles, delivering professional-grade finishes in furniture manufacturing, cabinetry, and construction projects. The combination of 3-inch length and 0.372" thread diameter offers optimal engagement depth for secure fastening in structural wood assemblies.

Specification Summary & Compliance

These wood screws feature precision right-hand threading with approximately 7 threads per inch and 0.372" thread diameter, ensuring consistent performance across applications. The flat head design conforms to standard profiles with 82° countersink angle compatibility. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and industrial suitability. The thread-forming construction meets industry standards for wood fastening applications, providing reliable performance in professional carpentry and construction environments.
