Key Features & Benefits at a Glance

  • Corrosion-resistant nylon construction ensures reliable performance in humid or chemical environments without rust or degradation.
  • Lightweight yet durable plastic material reduces overall assembly weight while maintaining structural integrity for non-load-bearing applications.
  • Wide temperature tolerance (-40° to 185°F) provides stable operation in both freezing and elevated temperature conditions.
  • External hex drive design allows for quick installation and removal with standard tools, improving assembly efficiency.
  • Class 6g thread fit with coarse 1.5mm pitch delivers secure fastening with reduced cross-threading risk in repeated use scenarios.
  • Full threading along 20mm length enables adjustable positioning and consistent grip across the entire fastener engagement.
  • RoHS 3 compliance meets international environmental standards for safe use in regulated industries.

Professional Applications & Engineering Value

These M10 metric hex head screws solve critical challenges in electrical enclosures, automotive trim, and food processing equipment where metal fasteners cause galvanic corrosion or conductivity issues. The black nylon plastic construction provides excellent electrical insulation and eliminates the need for additional isolation components. With coarse metric threading and Class 6g tolerance, these screws maintain reliable engagement in plastic and soft material applications where fine threads would strip easily. The fully threaded design ensures maximum holding power across the entire 20mm length, while the external hex drive accommodates high-speed assembly in production environments. Ideal for temperature-resistant applications from freezer systems to moderate heat exposure.

Specification Summary & Compliance

This M10 x 1.5mm x 20mm hex head screw features Metric coarse threading with Class 6g thread fit per ISO standards, ensuring precise dimensional accuracy for consistent performance. Manufactured from nylon plastic with black color throughout, the fastener maintains RoHS 3 (2015/863/EU) compliance for restricted substance control. The fully threaded configuration with external hex drive and standardized 16mm head width provides compatibility with common installation tools and procedures.
