• Regulatory compliance assurance meeting ASME B18.3 standards, RoHS 3, and REACH requirements for global industrial applications

Professional Applications & Engineering Value

These 10-32 UNF Class 3A set screws deliver exceptional engineering value in precision assembly applications where vibration resistance and secure positioning are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery operating in demanding environments, while the headless design with hex drive allows for flush mounting in space-constrained assemblies. The extended tip configuration maximizes surface contact with the mating component, distributing clamping force more effectively and preventing damage to precision shafts and collars. These fine thread set screws are particularly valuable in manufacturing equipment, automotive components, and precision instruments where Class 3A thread fit ensures minimal backlash and superior holding capability against rotational forces and vibration-induced loosening.

Specification Summary & Compliance

This set screw features precision 10-32 UNF fine threads with Class 3A thread fit for tight tolerance applications. The extended tip measures 0.127" diameter with controlled tolerances (-0.007" to 0") and 0.049" length (-0.005" to 0" tolerance). Manufactured to Rockwell B80 hardness specifications, the fastener complies with ASME B18.3 dimensional standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements for industrial use.
