Professional Applications & Engineering Value
This 0-80 UNF set screw delivers critical performance in precision assemblies where fine thread engagement and consistent clamping force are paramount. The black-oxide alloy steel construction provides enhanced corrosion protection while maintaining the Rockwell C45 hardness necessary for repeated adjustment cycles without thread deformation. Engineered with Class 3A thread fit and UNF fine threads, it eliminates backlash in sensitive positioning systems, making it ideal for precision equipment, aerospace components, and medical devices where vibration resistance and dimensional stability are critical. The headless hex drive design allows complete integration into collars, pulleys, and couplings while the cup tip ensures maximum contact pressure without damaging shaft surfaces.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision and UNF 0-80 fine threads (0.06" diameter, 5/32" length). The black-oxide alloy steel construction meets Rockwell C45 hardness requirements for consistent performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial applications.
