Key Features & Benefits at a Glance

  • Superior corrosion resistance due to nylon plastic material, ideal for humid or chemically exposed environments without risk of rust.
  • Reliable performance across wide temperature ranges from -40° to 140°F, maintaining integrity in varying operational conditions.
  • Precise and secure fastening with UNC coarse threading and Class 2A fit, ensuring easy installation and reduced cross-threading risks.
  • Durable, non-conductive properties of nylon provide electrical insulation and lightweight strength for sensitive assemblies.
  • Enhanced safety compliance meeting UL 94 V-2 flammability standards, RoHS 3, and REACH regulations for industrial use.
  • Efficient hex drive design with 5/64" drive size allows for tight spaces and secure torque application using standard tools.
  • Fully threaded construction offers consistent grip along the entire 1/4" length, improving load distribution and holding power.

Professional Applications & Engineering Value

This nylon plastic socket head cap screw is engineered to address common industrial challenges such as corrosion, electrical conductivity, and weight constraints. Its UNC coarse thread and Class 2A fit provide quick, reliable assembly in applications like electronics enclosures, automotive components, and machinery where metal fasteners could cause galvanic corrosion or short circuits. The right-hand thread direction and standard socket head profile ensure compatibility with automated equipment and manual tools, reducing installation time. Ideal for industrial plastic screws in temperature-sensitive settings, it maintains performance from -40° to 140°F, offering a lightweight yet robust alternative to metal options while meeting stringent UL 94 V-2 and environmental compliance standards.

Specification Summary & Compliance

This screw adheres to inch system dimensions with a thread fit of Class 2A for precise tolerance, UNC coarse threading, and a fully threaded rod type for consistent engagement. It complies with UL 94 V-2 for flammability resistance, RoHS 3 (2015/863/EU) for restricted hazardous substances, and REACH (EC 1907/2006) regulations, ensuring safety and environmental responsibility in industrial fastening applications.
