Professional Applications & Engineering Value
These No. 7 wood screws with integrated stainless steel/rubber washers solve critical moisture intrusion problems in wood, plastic, and composite material applications. The 18-8 stainless steel construction provides exceptional corrosion resistance for outdoor structures, decking, and marine environments where weather exposure compromises fastener integrity. The thread-cutting Type 17 point and square drive system combine to deliver rapid installation with reduced operator fatigue, while the flat head profile ensures seamless surface integration. The sealing washer technology prevents water penetration at the fastener head, extending service life in wood-plastic composite decking, outdoor furniture, and structural applications where moisture management is essential for long-term durability.
Specification Summary & Compliance
These 3" wood screws feature a No. 7 screw size with 0.151" thread diameter and approximately 16 threads per inch. The partially threaded design provides minimum 2" thread engagement with standard right-hand threading. Manufactured to precise dimensional standards with flat head configuration and square drive (No. 1) compatibility. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in commercial and industrial applications.
