Professional Applications & Engineering Value
This 8-32 UNC set screw is engineered to address critical challenges in industrial assemblies where vibration resistance and positional accuracy are paramount. The Black-Oxide Alloy Steel material, combined with Rockwell C45 hardness, provides excellent tensile strength and wear resistance, preventing failure under cyclic loads. The cup point tip ensures minimal surface damage while maintaining a firm grip, ideal for securing gears, pulleys, and collars on shafts. With its headless design and hex drive, it offers a low-profile solution for confined spaces, reducing the risk of interference in machinery. Compliant with ASME B18.3 specifications, this screw delivers consistent performance in automotive, aerospace, and manufacturing sectors, ensuring long-term operational stability.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit for precise dimensional accuracy and superior thread engagement. It conforms to ASME B18.3 standards (referencing ASTM F912) for manufacturing consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety requirements for industrial use.
