Professional Applications & Engineering Value
This 18-8 stainless steel set screw is engineered to address critical challenges in industrial assembly, such as loosening under vibration and corrosion in demanding conditions. Its headless design with a hex drive allows for flush mounting in tight spaces, while the coarse UNC thread ensures rapid and reliable fastening in materials like steel and aluminum. The Class 3A thread fit provides precise tolerances, reducing the risk of failure in high-stress applications like machinery, automotive components, and electrical enclosures. Made from durable stainless steel, it offers long-term reliability without the need for frequent maintenance, making it a cost-effective solution for B2B procurement in sectors requiring robust, compliant fasteners.
Specification Summary & Compliance
This set screw features a 5/16"-18 UNC coarse thread with a Class 3A thread fit for high precision and strength. It adheres to ASME B18.3 manufacturing standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met. Dimensions include a 2-1/2" length and 5/32" hex drive size, with a cup tip for secure fastening.
