Professional Applications & Engineering Value
Engineered for precision fastening in electronics, instrumentation, and aerospace assemblies, these 0-80 UNF flat head screws solve critical challenges in space-constrained applications. The passivated 18-8 stainless steel provides excellent corrosion resistance while maintaining 80,000 psi tensile strength, preventing failure in high-stress environments. The fine UNF threads with Class 2A fit ensure precise engagement in tapped holes, reducing the risk of cross-threading in delicate components. With 100° countersink angle and Phillips No. 0 drive, these screws enable flush mounting in thin panels while offering controlled installation torque. Fully compliant with ASME B18.6.3 standards, they deliver consistent performance in automated assembly systems and precision manufacturing applications where reliability is paramount.
Specification Summary & Compliance
This 0-80 UNF flat head machine screw features Class 2A thread fit per unified thread standards with 1/8" length and full threading. Manufactured to ASME B18.6.3 specifications with Rockwell B80 hardness and 80,000 psi tensile strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety and restricted substance control.
