S-90610A650 Length 4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding woodworking environments
• Maximum torque transmission through square drive design that prevents cam-out and reduces tool slippage during installation
• Strong, permanent thread engagement via thread forming technology that eliminates pre-tapping requirements while creating durable connections
• Optimized wood penetration with pointed tip design and partial threading for enhanced holding power in both hardwood and softwood applications
• Flush finishing capability with standard 82° flat head profile that seats perfectly with standard countersink angles
• Precise installation guidance with specific drill bit recommendations (9/64" for hardwood, 7/64" for softwood) to prevent wood splitting
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe industrial use and environmental responsibility

Professional Applications & Engineering Value

These No. 14 wood screws are engineered to solve common fastening challenges in wood construction and woodworking applications. The zinc-plated steel construction provides essential corrosion protection for interior and protected exterior applications, while the thread forming technology creates stronger thread engagement than conventional cutting threads by compressing wood fibers rather than removing them. This results in increased pull-out resistance and prevents loosening under vibration. The square drive system delivers superior torque transfer compared to Phillips heads, reducing installation time and driver bit wear. With specific drill bit sizing for both hardwood and softwood, these screws eliminate guesswork and prevent material damage, making them ideal for professional cabinetry, furniture manufacturing, and structural wood assemblies where reliability is critical.

Specification Summary & Compliance

These wood screws feature inch system measurements with No. 14 screw diameter (0.242") and 4" length with partial threading (minimum 2.667" thread length). The flat head design incorporates standard 82° countersink angle for flush mounting. Manufactured to precise dimensional standards with right-hand threading and approximately 10 threads per inch. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance for professional use.
