S-90000A159 Length 1 5/8" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in humid or outdoor environments
• Enhanced holding power through thread cutting design that creates precise mating threads in wood and plastic-wood composites
• Secure installation with square drive that provides excellent torque transmission and reduces cam-out risk
• Optimized material penetration with pointed tip and Type 17 thread design for easier starting and reduced splitting
• Reduced assembly time with partial threading that allows for faster driving while maintaining strong holding capability
• Environmental compliance meeting RoHS 3 and REACH standards for safe use in regulated applications
• Precision compatibility with 1/16" drill bits for proper pilot hole preparation in various materials

Professional Applications & Engineering Value

These No. 6 wood screws with thread cutting design solve critical fastening challenges in wood and plastic-wood composite applications. The 18-8 stainless steel construction provides exceptional corrosion resistance, making these flat head screws ideal for outdoor furniture, decking, and marine environments where moisture exposure is a concern. The square drive system ensures maximum torque transfer during installation, preventing stripping and reducing worker fatigue. With their Type 17 pointed tip and cutting threads, these fasteners eliminate the need for pre-tapping in many applications, significantly reducing installation time while providing superior pull-out resistance. The partially threaded design allows for precise clamping force distribution, preventing material damage while maintaining structural integrity in demanding wood and composite fastening scenarios.

Specification Summary & Compliance

These wood screws feature a No. 6 size with 1-5/8" length and 0.138" thread diameter. The threading specification includes 9 threads per inch with right-hand direction and partial threading extending to a minimum of 1.073". Manufactured to precise dimensional standards with a standard flat head profile and square drive (No. 2 size), these fasteners comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industry compliance requirements for hazardous substance restrictions.
