- High tensile strength of 80,000 psi ensures reliable fastening under substantial mechanical stress
- Rockwell B80 hardness provides excellent durability and resistance to wear during installation and use
- Full threading with Class 2A fit offers smooth engagement and consistent clamping force
- Undercut flat head design allows for flush mounting without protrusion for clean, professional finishes
- 82° countersink angle ensures proper seating in standard countersunk holes for secure fastening
- Compliance with ASME B18.6.3 guarantees dimensional accuracy and interchangeability in industrial applications
Professional Applications & Engineering Value
These 6-32 UNC flat head screws deliver critical engineering solutions where corrosion resistance and high-strength fastening are paramount. The Black-Oxide 18-8 Stainless Steel construction prevents rust and degradation in moisture-rich or chemical-exposed environments, while the fully threaded coarse UNC pattern ensures rapid installation and superior holding power in materials like metal, plastic, and wood. The undercut flat head profile eliminates gap issues common in standard flat heads, providing a truly flush surface that prevents snagging and maintains aerodynamic or aesthetic requirements. Ideal for industrial machinery, electronic enclosures, and automotive assemblies, these screws combine precise Phillips drive compatibility with robust 80,000 psi tensile strength to solve vibration-induced loosening and material fatigue challenges.
Specification Summary & Compliance
Manufactured to exact ASME B18.6.3 specifications, these screws maintain precise Class 2A thread fit tolerances for consistent performance. The 6-32 UNC coarse threads and 1/4" length adhere to standardized dimensions for reliable interchangeability. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and material restrictions are met, making them suitable for global industrial supply chains.
