Professional Applications & Engineering Value

This 6-32 UNC coarse thread nylon set screw is engineered to address critical challenges in electrical, automotive, and industrial applications where non-conductive, corrosion-resistant fasteners are essential. The nylon plastic material provides excellent insulation properties, preventing electrical conductivity and resisting chemical exposure, which is vital in PCB mounting, control panels, and marine equipment. Its headless design with a slotted drive enables flush installation, reducing protrusion in compact assemblies and minimizing snag risks in moving parts. The coarse UNC threads ensure quick, secure engagement in plastic or soft materials, while the Class 2A thread fit maintains precision for reliable torque transmission and vibration resistance. Ideal for securing knobs, gears, and sensors, this screw solves durability and safety concerns in harsh environments without compromising on regulatory compliance.

Specification Summary & Compliance

This set screw features a 6-32 UNC coarse thread with a Class 2A thread fit for standardized accuracy and ease of assembly. Key dimensions include a thread diameter of 0.138" and a length of 9/16", with a flat tip for focused clamping. It complies with RoHS 3 (2015/863/EU) regulations, ensuring it is free from hazardous substances, and is suitable for use in temperatures from -40° to 185° F. The right-hand thread direction and slotted drive style align with common industrial practices for efficient installation and maintenance.
