Professional Applications & Engineering Value
Engineered for precision industrial applications, this black-oxide alloy steel set screw addresses common engineering challenges in machinery assembly and component fixation. The Class 3A thread fit provides exceptional dimensional accuracy, eliminating play in rotating equipment while the cup tip design creates concentrated surface pressure for secure shaft positioning. The headless configuration with hex drive enables installation in space-constrained assemblies where protruding fasteners are impractical. With Rockwell C45 hardness and corrosion-resistant coating, this 6-32 UNC threaded fastener maintains clamping force in high-vibration environments, making it ideal for precision instruments, motor mounts, and automation equipment requiring reliable set screw performance.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision for superior dimensional control. The 6-32 UNC coarse thread maintains consistent engagement while the 3/8" length provides optimal fastening depth. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for international industrial applications.
