• Reliable torque transmission through the No. 2 Phillips drive, reducing cam-out and ensuring secure fastening
• Consistent thread engagement with Class 2A fit and fully threaded design for uniform load distribution and vibration resistance
• High mechanical strength delivering 70,000 psi tensile strength and Rockwell B80 hardness for demanding applications
• Enhanced surface durability via passivated finish that improves corrosion resistance and extends service life
• Regulatory compliance assurance meeting ASME B18.6.3 specifications and environmental standards including RoHS 3 and REACH

Professional Applications & Engineering Value

These 10-32 UNF flat head screws in 316 stainless steel address critical challenges in industrial fastening where corrosion resistance and precision matter most. The passivated finish provides an additional protective layer against corrosive agents, making these Phillips drive screws ideal for marine, chemical processing, and food equipment applications. The fully threaded design with fine thread spacing ensures maximum grip strength in thin materials and vibration-prone environments. With their 82° countersink angle and flat head profile, they deliver flush mounting for aerodynamic surfaces and safety-critical assemblies where protrusions are unacceptable. Engineered to ASME B18.6.3 standards, these screws provide reliable performance in machinery, electronic enclosures, and structural components requiring corrosion resistant fasteners with consistent dimensional accuracy.

Specification Summary & Compliance

These screws feature Class 2A thread fit per UNF standards, ensuring precise dimensional tolerances for reliable assembly. Manufacturing complies with ASME B18.6.3 specifications for flat head screw geometry and performance requirements. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming restriction of hazardous substances. The right-hand thread direction and fine thread spacing maintain compatibility with standard UNF threaded components across industrial applications.
