S-91087A128 1/4"-20 x 2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-phosphate steel coating for extended service life in demanding environments
• Enhanced torque transmission through T30 Torx drive system preventing cam-out and tool slippage
• Optimized material penetration with UNC coarse threading providing maximum holding power in wood and sheet metal
• Flush installation capability with standard 82° flat head profile for clean, professional finishes
• Reduced installation stress through thread-forming design that creates stronger mating threads without chip removal
• Full-length threading ensures consistent engagement along the entire 2" length for uniform load distribution
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These black-phosphate steel wood screws with T30 Torx drive are engineered to address common fastening challenges in industrial assembly and construction. The thread-forming UNC coarse thread design eliminates the need for pre-tapped holes while creating stronger, more vibration-resistant connections in both sheet metal and wood applications. The black-phosphate surface treatment provides exceptional corrosion protection, significantly extending service life in environments where moisture or chemical exposure may compromise fastener integrity. The combination of fully threaded design and standard flat head profile ensures consistent clamping force distribution and flush mounting, making these screws ideal for furniture manufacturing, structural wood framing, and metal-to-wood composite assemblies where reliability and professional finish are paramount.

Specification Summary & Compliance

Manufactured to precise dimensional standards with UNC coarse thread spacing and Class 2A thread tolerance for consistent performance. These 1/4"-20 x 2" screws feature a standard 82° countersink angle and require a No. 3 drill bit (0.213" diameter) for proper installation. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards are met for industrial and commercial applications worldwide.
