Professional Applications & Engineering Value

This 1/4"-20 UNC nylon set screw delivers exceptional value in applications requiring electrical insulation, chemical resistance, and lightweight fastening solutions. The headless design with slotted drive enables seamless integration where protruding fastener heads would interfere with mechanical operation or present safety hazards. Manufactured from durable off-white nylon plastic, these set screws effectively resist corrosion from moisture, chemicals, and environmental exposure while providing excellent dielectric properties. The coarse thread configuration ensures secure fastening in softer materials and plastics where fine threads might strip, making them ideal for electrical enclosures, consumer products, and light industrial assemblies requiring repeated adjustments without thread degradation.

Specification Summary & Compliance

This set screw features precise 1/4"-20 UNC coarse threads with Class 2A fit tolerance for consistent performance across manufacturing applications. The 19/32" length and flat tip design provide optimal engagement depth and surface contact. Manufactured in compliance with RoHS 3 (2015/863/EU) regulations, this fastener meets international standards for hazardous substance restrictions, ensuring environmental responsibility in industrial supply chains.
