Professional Applications & Engineering Value
This 1/4"-20 UNC Class 3A set screw is engineered to address critical challenges in industrial settings, such as component slippage and corrosion-induced failure. The 18-8 stainless steel material offers excellent resistance to rust and chemicals, making it suitable for machinery, automotive, and outdoor equipment where exposure to moisture is common. Its headless design with a hex drive allows for flush mounting in tight spaces, while the cup point provides a firm bite into shafts or hubs, preventing rotational movement. The coarse thread and right-hand direction ensure quick assembly and disassembly, reducing downtime in maintenance-heavy applications. By meeting ASME B18.3 specifications, this screw delivers consistent performance in high-stress environments, enhancing the reliability of your assemblies.
Specification Summary & Compliance
This set screw features precise Class 3A thread fit for tight tolerances and optimal engagement, with UNC 1/4"-20 coarse threads and a right-hand direction. It complies with ASME B18.3 manufacturing standards and is verified to be RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to environmental and safety regulations for industrial use.
