Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 1-64 UNC flat head Phillips machine screws solve critical fastening challenges in machinery, electronics, and automotive assemblies. The passivated 18-8 stainless steel construction provides exceptional resistance to oxidation and chemical exposure, while the coarse UNC threading with Class 2A fit ensures rapid installation and reliable performance in high-vibration environments. The 82° countersink angle enables flush mounting in precision components, eliminating protrusions that could interfere with mechanical operations. With full threading along the 3/16" length, these screws distribute clamp force evenly, preventing joint failure in industrial equipment and metal fabrication applications where dimensional stability is paramount.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 standards with Class 2A thread fit tolerance for consistent mating with UNC nuts and threaded holes. The inch-dimensioned 1-64 UNC coarse thread maintains precise spacing for reliable engagement. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety in global supply chains. Mechanical properties include 80,000 psi tensile strength and Rockwell B80 hardness for guaranteed performance in industrial fastening applications.
