- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh chemical and marine environments
- Exceptional mechanical strength offering 70,000 psi tensile strength and Rockwell B80 hardness for reliable load-bearing performance
- Optimized for flush mounting with standard flat head profile and 82° countersink angle for seamless surface integration
- Enhanced installation efficiency through Phillips No. 2 drive design, reducing cam-out risks during high-torque applications
- Consistent threading performance with UNC coarse threads and Class 2A fit ensuring secure fastening in various materials
- Long-term environmental compliance with RoHS 3 and REACH regulations, meeting global environmental safety standards
- Full-thread engagement capability providing maximum grip strength across the entire 1-1/4" length
Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 316 stainless steel flat head screws deliver critical corrosion resistance where exposure to chemicals, saltwater, or extreme weather conditions would compromise ordinary fasteners. The passivated finish enhances surface durability while maintaining the material's inherent anti-corrosive properties. The combination of UNC coarse threading and Class 2A fit ensures rapid installation with reduced cross-threading risks in assembly line environments. These Phillips drive screws are particularly valuable in marine equipment, chemical processing installations, and food processing machinery where both corrosion resistance and regulatory compliance are mandatory. The fully threaded design provides uniform stress distribution, making them ideal for applications requiring consistent clamping force along the entire fastener length.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent performance. Features UNC coarse threads (6-32) with standard 82° countersink angle and right-hand thread direction. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring adherence to international safety standards for hazardous substance restrictions.
