Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional performance in demanding industrial applications where vibration resistance and precise positioning are critical. The Class 3A UNF fine threads provide superior clamping force for machinery components, while the headless hex drive design enables flush mounting in precision equipment and rotating assemblies. The Rockwell C45 hardness rating ensures the fastener maintains its integrity under repeated stress cycles, making it ideal for automotive, aerospace, and heavy equipment applications. The black-oxide surface treatment offers reliable corrosion protection in environments exposed to moisture and chemicals, significantly extending service intervals and reducing maintenance costs.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 standards with Class 3A thread fit precision and UNF 3/8"-24 fine thread specifications. The 3/4" length and flat tip design ensure consistent seating in mating components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making this set screw suitable for global supply chain requirements.
