Professional Applications & Engineering Value
This 6-40 UNF fine thread nylon set screw solves critical challenges in precision assemblies where metal fasteners would cause galvanic corrosion, electrical shorts, or component damage. The engineering-grade nylon plastic construction provides inherent dielectric properties perfect for electrical enclosures, while the Class 2A thread fit ensures repeatable installation torque in vibration-prone applications. The 1/16" hex drive accommodates standard tools for efficient installation in headless set screw configurations where protruding fasteners are unacceptable. Ideal for securing knobs, pulleys, and small mechanisms in electronics, medical devices, and food processing equipment, this temperature-resistant set screw maintains clamping force from sub-zero to elevated temperature environments.
Specification Summary & Compliance
Manufactured to UNF thread standards with Class 2A thread fit tolerance for precision engagement. Features 6-40 thread size with 0.138" diameter and 3/8" length in inch system measurements. The flat tip design and right-hand thread direction provide standardized installation. Compliant with RoHS 3 (2015/863/EU) regulations for hazardous substance restriction, ensuring environmental responsibility in industrial applications.
