Professional Applications & Engineering Value
These 1-72 UNF Class 3A set screws deliver exceptional performance in precision assemblies where space constraints and vibration resistance are critical concerns. The 18-8 stainless steel composition provides excellent corrosion resistance for applications in electronics, aerospace components, and medical devices exposed to harsh environments. The fine thread spacing and Class 3A thread fit ensure minimal backlash and superior clamping force distribution, effectively preventing loosening under dynamic loads. The headless design with hex drive enables installation in confined spaces while the cup tip creates secure contact points without damaging precision-machined surfaces. These industrial set screws are engineered to maintain positional accuracy in rotating assemblies, alignment systems, and precision instrumentation where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 standards with Class 3A thread fit precision and UNF fine thread specifications (1-72 thread size, 0.073" diameter). The 18-8 stainless steel construction achieves Rockwell B80 hardness for optimal mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets and industrial applications.
