Professional Applications & Engineering Value
These 1-72 UNF set screws deliver exceptional engineering value in applications requiring precise component positioning and vibration resistance. The 18-8 stainless steel material provides reliable corrosion resistance for machinery exposed to moisture, chemicals, or outdoor conditions. The Class 3A thread fit ensures minimal backlash and superior clamping force in precision assemblies, while the headless hex design allows installation in confined spaces where traditional fasteners cannot be used. The fine UNF threads offer increased tensile strength compared to coarse threads, making these set screws ideal for securing gears, pulleys, and collars on shafts in automotive, aerospace, and manufacturing equipment where reliable fastening solutions are critical to operational safety and performance.
Specification Summary & Compliance
This precision set screw features 1-72 UNF fine threads with Class 3A thread fit for superior dimensional accuracy and tight tolerances. The fastener is manufactured to meet ASME B18.3 specifications ensuring consistent quality and performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence for global industrial applications.
