Professional Applications & Engineering Value
This 4-40 UNC nylon plastic set screw is engineered to address common challenges in precision industries, such as electronics, automotive, and consumer goods. Its non-conductive and corrosion-resistant properties eliminate galvanic corrosion risks when used with dissimilar metals, ensuring electrical safety in PCB mounts and connector assemblies. The coarse UNC thread and Class 2A fit enable quick, reliable fastening in plastics and soft metals, reducing installation time and tool wear. With a headless hex drive design, it provides flush mounting in confined spaces, preventing interference in moving parts. Ideal for applications requiring lightweight, temperature-resistant fasteners that comply with RoHS 3 standards, this screw enhances product durability and regulatory adherence.
Specification Summary & Compliance
This set screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. It features a 4-40 thread size, 3/32" length, and coarse thread spacing, manufactured from off-white nylon plastic. The product is fully RoHS 3 (2015/863/EU) compliant, ensuring it meets strict environmental regulations for hazardous substance restrictions.
