• Optimized thread engagement with partial threading for controlled penetration in wood materials
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for industrial use

Professional Applications & Engineering Value

These self-drilling wood screws deliver exceptional engineering value by combining 18-8 stainless steel durability with advanced fastening technology. The thread cutting design creates precise mating threads in wood substrates, while the locking serrations beneath the flat head provide permanent anti-rotation security. The square drive system ensures maximum torque transfer without stripping, and the right hand thread configuration with partial threading allows for controlled depth penetration. These features collectively solve common wood fastening challenges including material splitting, screw back-out, and corrosion-induced failure, making them ideal for construction, furniture assembly, and outdoor wood structures where reliability is paramount.

Specification Summary & Compliance

This No. 6 size screw features a 1 5/8" length with Class 2A thread tolerances and standard thread cutting specifications. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe industrial use. The 90° countersink angle and standard flat head profile maintain consistent installation quality across wood applications.
