Professional Applications & Engineering Value
This 0-80 UNF flat head screw delivers critical engineering solutions where space constraints and material integrity are paramount. The passivated 18-8 stainless steel construction provides excellent resistance to oxidation and chemical exposure, making it suitable for electronics, precision instruments, and marine applications. The UNF fine thread configuration maintains holding power in thin-section assemblies, while the 82° countersink angle ensures flush seating without protruding edges. With fully threaded design and Phillips No. 0 drive, installers achieve consistent clamping force and reduced installation time in automated or manual assembly processes. These flat head machine screws are engineered to prevent loosening under vibration while meeting strict dimensional tolerances for repeatable performance in high-volume manufacturing environments.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 dimensional standards with Class 2A thread fit for consistent interchangeability. The UNF 0-80 fine thread maintains precise pitch control while the 5/32" length provides standardized engagement depth. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial supply chains. Mechanical properties include 80,000 psi tensile strength and Rockwell B80 hardness verification for quality assurance.
