Professional Applications & Engineering Value
This 10-32 UNF set screw delivers critical engineering solutions for precision machinery, automotive assemblies, and industrial equipment where vibration resistance and positional stability are paramount. The 18-8 Stainless Steel construction provides inherent corrosion resistance, eliminating failure points in humid or chemically aggressive environments. The Class 3A thread fit ensures tighter tolerances than standard fasteners, preventing loosening under dynamic loads while the hex headless design allows flush mounting in confined spaces. The soft silver tip protects precision shafts and components from damage during clamping operations, making these set screws ideal for permanent positioning of gears, pulleys, and collars on rotating assemblies.
Specification Summary & Compliance
This precision fastener features 10-32 UNF fine threads with Class 3A thread fit for superior dimensional accuracy and holding capability. Manufactured to ASME B18.3 specifications with Rockwell B80 hardness rating. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
