S-90294A509 Length 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for humid or chemically aggressive environments
• Enhanced holding power through thread-forming design that creates strong, permanent threads in wood materials
• Clean, flush installation with standard 82° flat head profile that sits perfectly countersunk in wood surfaces
• Full threading along entire shank length ensures maximum grip and prevents material separation in wood applications
• Optimized for both hardwood and softwood with specific drill bit size recommendations for precise, split-free installation
• Reliable driving performance with Phillips No. 1 drive that provides secure tool engagement and reduces cam-out risk
• Compliance with global environmental standards including RoHS 3 and REACH for safe industrial use

Professional Applications & Engineering Value

These 316 stainless steel wood screws deliver exceptional performance in demanding wood fastening applications where corrosion resistance is critical. The thread-forming design eliminates the need for pre-tapped holes while creating strong, permanent threads that resist loosening under vibration and load cycles. The fully threaded configuration provides maximum surface contact along the entire fastener length, distributing stress evenly and preventing wood splitting. The 82° flat head with standard profile ensures clean, flush installation in furniture manufacturing, marine environments, outdoor structures, and architectural woodwork. These Phillips drive wood screws are engineered to maintain integrity in high-moisture applications while meeting strict industrial compliance requirements.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with No. 4 screw size, 1/2" length, and 0.112" thread diameter. Features right-hand threading with approximately 22 threads per inch and pointed tip for easy starting. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial applications. The thread-forming tapping method provides reliable performance in both hardwood (1/16" drill bit) and softwood (3/64" drill bit) applications with standard 82° countersink angle compatibility.
