Professional Applications & Engineering Value
These 1-72 UNF fine thread screws deliver critical engineering value in precision assembly applications where vibration resistance and corrosion protection are paramount. The 18-8 stainless steel composition combined with passivated finish creates a robust barrier against chemical exposure and environmental degradation, making them ideal for electronics, instrumentation, and marine equipment. The Class 2A thread fit ensures consistent torque values and reliable clamping force in fine-pitch applications, while the rounded head design with slotted drive provides secure seating without damaging sensitive surfaces. These fully threaded screws maintain their 100,000 psi tensile strength across the entire 3/8" length, offering uniform load distribution in compact assemblies where space constraints demand maximum fastening efficiency.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and UNF fine thread specifications ensuring interchangeability and reliable performance. These screws conform to ASME B18.6.3 mechanical and dimensional requirements, providing industry-standard quality assurance. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for global industrial applications.
