S-98643A640 Length 3" Wood Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 Stainless Steel construction ensures long-term reliability in humid or outdoor wood applications.
• Self-drilling tip eliminates pre-drilling, saving significant labor time and reducing installation errors.
• Thread cutting design with 13 TPI creates clean, secure threads in wood for superior pull-out resistance.
• Square drive and flat head with 90° countersink provide a flush, non-snag finish and prevent cam-out during high-torque installation.
• Serrations under the head enhance locking capability, preventing loosening from vibration in dynamic structures.
• 2" minimum thread length offers deep, robust engagement for maximum holding power in demanding wood assemblies.
• Compliance with RoHS 3 and REACH guarantees environmentally safe materials, meeting strict international regulatory standards.

Professional Applications & Engineering Value

These No. 10 x 3" self-drilling wood screws are engineered to address common inefficiencies in wood construction and fabrication. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making them ideal for outdoor decking, marine applications, and high-moisture environments. The thread cutting action and self-drilling tip eliminate the need for separate pilot holes, reducing labor time and tool changes while minimizing wood splitting. Combined with the square drive for secure torque transfer and serrated locking to resist vibration-induced loosening, these screws deliver reliable, long-lasting fastening for structural wood connections, furniture assembly, and timber framing projects.

Specification Summary & Compliance

This screw features a No. 10 size with a 0.19" thread diameter and 13 threads per inch, providing precise engagement in wood. The flat head is designed with a standard profile and 90° countersink angle for seamless installation. Manufacturing and material compliance include RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring adherence to environmental and safety regulations for industrial and construction use.
