Professional Applications & Engineering Value
This nylon plastic set screw with 4-40 UNC coarse thread and headless design addresses critical engineering challenges in applications requiring non-metallic fasteners. Its off-white nylon material provides inherent chemical resistance, eliminating galvanic corrosion risks when mating with dissimilar metals. The flat tip and right-hand thread configuration deliver uniform clamping force in precision assemblies, while the 3/4" length offers sufficient engagement depth for secure positioning. Ideal for electrical enclosures, medical devices, and food processing equipment, this fastener combines electrical insulation with reliable mechanical performance where conductivity or metal contamination must be avoided.
Specification Summary & Compliance
This set screw maintains Class 2A thread fit per UNC standards, ensuring dimensional accuracy and interchangeability. The 3/64" hex drive provides precise installation control, while the coarse thread spacing enhances assembly efficiency. Manufactured to meet RoHS 3 (2015/863/EU) compliance, it contains no restricted hazardous substances, supporting sustainable manufacturing practices and global regulatory requirements for electronic and industrial applications.
