Professional Applications & Engineering Value
This 0-80 UNF fine thread set screw is engineered to address common challenges in precision assemblies, such as component slippage and surface damage. The 18-8 stainless steel material offers excellent corrosion resistance, which is vital for applications exposed to moisture or chemicals. Its Class 3A thread fit provides tighter tolerances, reducing the risk of thread stripping and ensuring a secure hold in delicate machinery. The green nylon 6/6 plastic tip acts as a resilient locking element, minimizing vibration-induced loosening while preventing marring of finished surfaces—ideal for use in electronics, automotive controls, and optical equipment. By integrating a hex drive and headless design, it facilitates easy installation in tight spaces, enhancing assembly efficiency and reliability.
Specification Summary & Compliance
This set screw features a 0-80 UNF fine thread with Class 3A fit for high precision, adhering to ASME B18.3 specifications. It is manufactured from 18-8 stainless steel with a Rockwell B80 hardness, ensuring durability. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), affirming its safety and environmental standards.
