• Optimized thread engagement with 5 TPI coarse threads and partial threading for faster installation and reduced wood splitting
• Heavy-duty construction with 5/8" diameter and 8" length, engineered for demanding structural wood fastening applications
• Industry-standard compliance meeting ASME B18.2.1 and ASTM A307 specifications for reliable performance and interchangeability
• Environmental responsibility with RoHS 3 and REACH compliance, ensuring safe use in regulated applications

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws deliver exceptional performance in demanding construction and industrial applications where corrosion resistance and structural integrity are paramount. The thread-forming design eliminates the need for pre-drilling in many wood types, creating stronger, permanent threads that resist loosening from vibration and seasonal wood movement. The external hex drive system provides superior torque capability for high-clamp force applications in timber framing, deck construction, and heavy timber connections. With 5/8" diameter and 8" length, these screws are engineered for structural wood-to-wood connections, outdoor installations, and industrial wood assemblies where traditional fasteners may fail under stress or environmental exposure.

Specification Summary & Compliance

Manufactured to exacting standards with 5/8" diameter and 8" length, featuring 5 TPI coarse threads in right-hand direction with partial threading. These screws conform to ASME B18.2.1 dimensional specifications and ASTM A307 material standards for mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safe use in regulated environments. The hot-dipped galvanized surface treatment provides consistent corrosion protection meeting industrial requirements for outdoor and high-humidity applications.
