Professional Applications & Engineering Value
These 0-80 UNF flat head Phillips machine screws deliver critical performance in precision assemblies where space constraints and corrosion resistance are paramount. The passivated 18-8 stainless steel construction provides excellent protection against oxidation and chemical exposure, making them ideal for electronic enclosures, instrumentation, aerospace components, and medical devices. The fine UNF threading with Class 2A fit ensures precise engagement in tapped holes, while the 82° countersink angle creates flush surfaces essential for aerodynamic and aesthetic applications. The combination of 80,000 psi tensile strength and fully threaded design provides superior pull-out resistance in thin-section materials, solving common fastening challenges in compact industrial designs.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerance for precision assembly. The 0-80 UNF fine thread configuration ensures secure fastening in demanding applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe use across global markets. The right-hand threaded, fully threaded design with standard flat head profile and 82° countersink angle meets industry-standard dimensional requirements for consistent performance.
