Professional Applications & Engineering Value
This 1/2"-13 UNC set screw is engineered to address critical challenges in industrial assembly, where vibration resistance and permanent positioning are paramount. The cup point tip creates a firm bite into shafts, gears, and collars, preventing rotational slippage under dynamic loads. Manufactured from zinc plated alloy steel, it combats corrosion in harsh settings like machinery, automotive systems, and heavy equipment. The hex headless design allows seamless integration into tight spaces, eliminating interference while maintaining a clean profile. With coarse thread spacing and Class 3A fit, it ensures rapid installation and reliable performance in right-hand thread applications, reducing downtime and enhancing operational efficiency.
Specification Summary & Compliance
This set screw adheres to inch system dimensions with a thread size of 1/2"-13 UNC and Class 3A precision for superior thread engagement. It meets ASME B18.3 manufacturing specifications, ensuring consistent quality and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and restricted substance control.
