Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional performance in demanding mechanical systems where vibration resistance and precise component positioning are critical. The 3/8"-24 UNF fine threads with Class 3A precision fit provide superior clamping force distribution, preventing backlash in precision machinery, automotive assemblies, and industrial equipment. The combination of Rockwell C45 hardness and black-oxide surface treatment ensures durability against wear and environmental exposure, while the hex drive and headless design facilitate installation in confined spaces. The oval tip minimizes stress concentration on shaft surfaces, making it ideal for permanent positioning applications requiring repeated adjustments without compromising structural integrity.
Specification Summary & Compliance
This set screw features 3/8"-24 UNF fine threads with Class 3A thread fit (tight tolerance for external threads) and complies with ASME B18.3 manufacturing specifications. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental safety and regulatory acceptance for international industrial markets. Manufactured to inch system standards with precise dimensional control for reliable performance in critical fastening applications.
