Key Features & Benefits at a Glance
- Superior corrosion resistance in harsh environments due to 316 Stainless Steel construction with passivated finish
- Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness for reliable load-bearing performance
- Precision thread engagement with Class 3A thread fit ensuring secure fastening and vibration resistance
- Optimized flush mounting with standard 82° countersink angle and flat head design for seamless surface integration
- Enhanced installation efficiency through 3/32" hex drive design preventing cam-out during high-torque applications
- Full-threaded reliability providing consistent clamping force across the entire 1-3/4" length
- Industry compliance assurance meeting ASME B18.3 specifications for dimensional accuracy and performance
Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 8-32 UNC flat head screws deliver critical performance advantages in corrosive environments where standard fasteners fail. The 316 Stainless Steel material combined with passivated finish provides exceptional resistance to chemicals, saltwater, and industrial atmospheres, making them ideal for marine equipment, chemical processing plants, and food processing machinery. The Class 3A thread fit and coarse UNC threading ensure rapid assembly with minimal cross-threading risk, while the fully threaded design maintains consistent clamping force in vibration-prone applications. The 82° countersink angle and flat head profile create flush surface finishes essential for aerodynamic components, machinery guards, and precision instruments where protrusions compromise performance.
Specification Summary & Compliance
These flat head screws feature precision 8-32 UNC coarse threads with Class 3A thread fit tolerance for superior engagement. Manufacturing complies with ASME B18.3 specifications ensuring dimensional accuracy for head diameter (0.359"), length (1-3/4"), and drive size (3/32"). Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, confirming they're free from restricted hazardous substances for global industrial use.
