- Superior corrosion resistance with zinc-plated steel construction for long-lasting performance in various environments
- Enhanced driving efficiency with Phillips No. 2 drive that prevents cam-out and ensures secure installation
- Optimal material engagement through partial threading design that provides excellent pull-out resistance in wood applications
- Flush finishing capability with standard flat head profile and 82° countersink angle for professional-looking results
- Versatile wood compatibility with specific drill bit recommendations for both hardwood (7/64") and softwood (5/64") applications
- Reliable thread formation using thread-forming tapping method that creates strong, permanent connections in wood materials
- Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe, sustainable usage
Professional Applications & Engineering Value
These No. 9 zinc-plated steel wood screws are engineered to address common challenges in wood fastening applications. The thread-forming design eliminates the need for pre-tapped holes while creating strong, permanent threads in wood substrates. The partial threading configuration concentrates holding power where it's needed most, preventing wood splitting while maximizing pull-out resistance. The Phillips flat head combination ensures flush installation with standard countersink tools, making these screws ideal for furniture assembly, cabinetry, and general woodworking where appearance and structural integrity matter. The specific drill bit recommendations for different wood types eliminate guesswork and ensure proper fit in both hardwood and softwood applications.
Specification Summary & Compliance
These partially threaded wood screws feature precise inch system dimensions including No. 9 screw size, 1-1/4" length, 0.177" thread diameter, and 14 TPI thread pitch. The manufacturing complies with standard flat head profile specifications and 82° countersink angle requirements. These fasteners are fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental safety and regulatory adherence for professional and industrial use.
