Professional Applications & Engineering Value
This 4-40 UNC Nylon Plastic set screw is engineered to address common industrial challenges, such as corrosion in moist or chemical-exposed settings and electrical insulation needs in electronic devices. The Nylon material offers inherent resistance to oils, solvents, and UV exposure, while the coarse UNC thread and Class 2A fit ensure quick, reliable assembly with high repeatability. Its headless, hex drive design is perfect for applications where space is limited, such as in machinery adjustments, consumer electronics, and automotive components, providing a secure hold without protruding parts. The flat tip minimizes damage to contacted surfaces, making it ideal for precision shaft securing and alignment tasks in manufacturing and maintenance.
Specification Summary & Compliance
This set screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. It features a right-hand thread direction, coarse thread spacing, and is manufactured to meet RoHS 3 (2015/863/EU) compliance, ensuring it is free from restricted hazardous substances. The specifications include a thread size of 4-40, 1" length, and 3/64" hex drive, providing reliable performance in inch-based measurement systems for various industrial applications.
