Key Features & Benefits at a Glance

  • Corrosion-resistant polypropylene construction ensures reliable performance in humid or chemical environments without rust or degradation.
  • Precise Class 2A thread fit guarantees smooth assembly and secure fastening with minimal risk of cross-threading in fine-thread applications.
  • Wide temperature tolerance from -20° to 210° F maintains structural integrity in varying thermal conditions for outdoor or industrial use.
  • Standard hex socket drive (5/32") allows for easy installation with common tools while providing a clean, flush finish.
  • Lightweight, non-conductive plastic material reduces overall component weight and eliminates electrical conductivity risks.
  • Full compliance with RoHS 3 and REACH regulations meets stringent industrial safety and environmental standards for global supply chains.
  • Off-white color and durable finish offer aesthetic consistency and resistance to UV exposure in visible assemblies.

Professional Applications & Engineering Value

This 10-32 UNF fine thread socket head cap screw delivers exceptional value in precision-driven industries where metal fasteners pose conductivity or corrosion concerns. Engineered from high-grade polypropylene plastic, it provides excellent chemical resistance and electrical insulation, making it ideal for electrical enclosures, laboratory equipment, and food processing machinery. The fine UNF threading and Class 2A fit ensure vibration-resistant, leak-proof connections in tight-tolerance assemblies, while the hex drive design facilitates quick maintenance in confined spaces. Its ability to withstand temperatures from -20° to 210° F supports use in automotive components and outdoor installations, reducing failure risks from thermal expansion.

Specification Summary & Compliance

This screw adheres to UNF fine thread standards with a Class 2A thread fit for consistent dimensional accuracy. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of restricted hazardous substances. The fully threaded rod type and standardized socket head profile provide uniform load distribution and reliable performance in industrial applications.
