S-90031A306 Length 3 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Enhanced holding power through thread forming technology that creates stronger, more permanent connections in wood materials
• Optimized wood penetration with pointed tip and specific drill bit recommendations for both hardwood (1/8") and softwood (7/64") applications
• Clean, flush installation with standard flat head profile and 82° countersink angle for professional finishing
• Reliable driving performance with No. 3 Phillips drive that resists cam-out during installation
• Versatile partial threading design that provides both strong thread engagement and efficient material clamping
• Industry compliance assurance meeting RoHS 3 and REACH environmental standards for global manufacturing use

Professional Applications & Engineering Value

These No. 12 wood screws are engineered to solve common fastening challenges in wood construction and manufacturing. The zinc-plated steel construction provides essential corrosion protection for both interior and exterior applications, while the thread forming technology eliminates the need for pre-tapped holes, creating stronger molecular bonds in wood fibers. The partially threaded design with right-hand threading ensures maximum pull-out resistance while allowing for precise material clamping. With specific drill bit sizing for both hardwood and softwood applications, these Phillips flat head screws deliver consistent performance in furniture manufacturing, construction framing, and woodworking projects where reliable holding power and professional finish are critical requirements.

Specification Summary & Compliance

Manufactured to precise inch system specifications with 0.216" thread diameter and 11 threads per inch for optimal wood engagement. Features standard flat head profile with 82° countersink angle and No. 3 Phillips drive compatibility. The 3-1/2" length with 2-1/2" minimum thread length provides substantial fastening depth. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial and commercial applications.
