Key Features & Benefits at a Glance

  • Non-conductive and corrosion-resistant nylon plastic construction ensures electrical safety and long-term reliability in sensitive environments
  • Wide temperature tolerance from -40°F to 185°F maintains structural integrity across diverse operating conditions
  • Class 2A thread fit provides consistent engagement and reliable fastening performance with standard UNC threaded components
  • Headless slotted design enables flush mounting and space-saving installation in confined applications
  • RoHS 3 compliance guarantees environmental responsibility and regulatory acceptance for global manufacturing
  • Coarse UNC threading ensures quick assembly and reduced cross-threading risks during high-volume production
  • Off-white color offers visual contrast for inspection and blends discreetly in finished assemblies

Professional Applications & Engineering Value

This 1/4"-20 nylon plastic set screw delivers critical performance advantages where metal fasteners fail. The non-conductive properties eliminate electrical short risks in electronics enclosures, while the corrosion-resistant material withstands harsh chemicals and moisture without degradation. The headless slotted drive design provides flush surface mounting for rotating components, shaft collars, and precision machinery where protrusions cause interference. With UNC coarse threads and Class 2A thread fit, installation becomes faster and more reliable in automated assembly lines. Ideal for electrical panels, medical devices, and food processing equipment where temperature resistance and regulatory compliance are mandatory.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerance for consistent performance. Features UNC coarse threads (1/4"-20) with right-hand direction and flat tip configuration. Fully compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring hazardous substance-free construction. Temperature rating maintained from -40°F to 185°F without performance degradation.
