S-90000A611 Length 3 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or outdoor wood applications
• Enhanced driving efficiency through the square drive design, reducing cam-out and providing secure torque transfer during installation
• Stronger thread engagement via thread cutting technology, creating precise mating threads in wood and plastic-wood composites for superior pull-out resistance
• Optimized material displacement with partial threading design, minimizing splitting while maintaining maximum holding power in dense materials
• Secure flush mounting with standard flat head profile, allowing for clean, recessed installations in wood surfaces
• Precision installation compatibility with recommended 7/64" drill bit, ensuring proper pilot hole sizing for reduced installation stress
• Environmental compliance assurance meeting RoHS 3 and REACH standards, making them suitable for regulated industrial and commercial projects

Professional Applications & Engineering Value

These No. 12 wood screws with thread cutting design solve critical fastening challenges in wood and plastic-wood composite applications. The 18-8 stainless steel composition provides exceptional resistance to corrosion and weathering, making them ideal for outdoor structures, decking, and marine environments where moisture exposure is common. The square drive system delivers superior torque transmission compared to traditional Phillips drives, preventing stripping during high-torque installation in hardwoods. The thread cutting technology creates clean, precise threads in materials without pre-tapping, reducing installation time while ensuring strong, reliable connections that resist vibration loosening. The partial threading design allows the unthreaded shank to act as a shear plane, providing enhanced resistance to pull-out forces in structural applications.

Specification Summary & Compliance

These screws feature a No. 12 size with 0.216" thread diameter and 7 threads per inch in right-hand direction. The 3-1/2" length provides ample engagement depth for substantial wood members. Manufacturing follows standard inch system specifications with Class 2A thread tolerances ensuring proper fit. The products are fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial use.
