Professional Applications & Engineering Value

This 6-40 UNF fine thread nylon plastic set screw is engineered to address common industrial challenges, such as corrosion in chemical-laden or humid settings. Made from durable nylon plastic, it prevents galvanic corrosion when used with dissimilar metals and provides electrical insulation, making it ideal for electronics, machinery, and automotive assemblies. The headless flat tip ensures a seamless fit in collars, shafts, and knobs, minimizing vibration loosening while the Class 2A thread fit and right-hand thread direction deliver consistent, reliable clamping force. Its RoHS 3 compliance supports sustainable manufacturing, and the broad temperature range from -40° to 185°F ensures durability in both freezing and moderate heat conditions, reducing maintenance needs in industrial plastic fasteners applications.

Specification Summary & Compliance

This set screw adheres to UNF fine thread standards with a Class 2A thread fit for precise dimensional accuracy, featuring a 6-40 thread size, 1" length, and 1/16" hex drive. It is manufactured to meet RoHS 3 (2015/863/EU) compliance, ensuring it is free from hazardous substances. The flat tip and headless design align with common industrial specifications for secure, low-profile fastening solutions.
