Professional Applications & Engineering Value
This 5-40 UNC set screw is engineered to address common industrial challenges, such as component slippage and corrosion-induced failure. Crafted from 18-8 Stainless Steel, it offers exceptional resistance to rust and chemicals, making it ideal for machinery, automotive assemblies, and electronic enclosures exposed to moisture. The headless design and 1/16" hex drive enable flush mounting in tight spaces, while the Class 3A thread fit and coarse thread spacing ensure a tight, reliable hold that withstands vibrations. The cup tip provides concentrated contact pressure, preventing loosening in dynamic applications. By integrating these features, this set screw enhances operational reliability and reduces maintenance needs in precision engineering and manufacturing settings.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, with a Class 3A thread fit for high precision and a thread size of 5-40 UNC with coarse spacing. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
