Professional Applications & Engineering Value

This 4-40 UNC nylon plastic set screw is engineered to address critical challenges in precision assemblies where metal fasteners fall short. Its off-white nylon material provides inherent non-conductive and corrosion-resistant properties, making it perfect for electrical enclosures, medical devices, and food processing equipment. The coarse UNC thread and Class 2A fit ensure quick, reliable installation with minimal cross-threading risk, while the flat tip design offers a secure, flush hold on shafts or components. Operating seamlessly across a broad temperature range, it eliminates thermal expansion issues common in plastics, delivering durable performance in automated machinery, sensor mounts, and consumer electronics without galvanic corrosion or conductivity concerns.

Specification Summary & Compliance

This set screw adheres to UNC coarse thread standards with a 4-40 thread size and Class 2A thread fit for precise dimensional accuracy. It features a right-hand thread direction, 1-3/4" length, and 3/64" hex drive for consistent manufacturability. The product is fully RoHS 3 (2015/863/EU) Compliant, meeting stringent environmental regulations for hazardous substance restrictions, and is manufactured to standard industrial specifications for reliable use in technical applications.
