- Broad industrial compliance meeting ASME B18.3 standards and environmental regulations
Professional Applications & Engineering Value
This 10-32 UNF Class 3A brass set screw delivers exceptional engineering value for precision assembly applications. The fine thread spacing and Class 3A thread fit provide superior clamping force and vibration resistance in machinery, electrical components, and instrumentation. The headless design with cup point creates permanent positioning without protruding hardware, ideal for rotating assemblies and alignment-critical systems. Manufactured from brass material, it offers excellent corrosion resistance while maintaining Rockwell B55 hardness for repeated adjustments without deformation. These industrial set screws solve common challenges of space limitations, corrosion concerns, and precision positioning requirements across manufacturing and maintenance operations.
Specification Summary & Compliance
This precision fastener features 10-32 UNF fine threads with Class 3A thread fit for tight tolerance applications. The 1/4" length and 3/32" hex drive provide standardized dimensions per ASME B18.3 specifications. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across regulated industries. The right-hand thread direction and cup point tip deliver consistent performance in alignment and locking applications.
