Key Features & Benefits at a Glance

  • Corrosion-resistant nylon construction ensures reliable performance in humid or chemical environments without rust or degradation.
  • Class 6g thread fit with coarse 1 mm pitch provides smooth, secure engagement and reduces cross-threading risks during assembly.
  • Wide temperature tolerance (-40° to 185°F) maintains structural integrity in both freezing and elevated heat conditions.
  • External hex drive design allows for high-torque application using standard tools, ensuring tight, vibration-resistant fastening.
  • RoHS 3 compliance guarantees environmentally safe material use, meeting strict EU regulatory standards for industrial components.
  • Fully threaded shank offers consistent grip along the entire 16 mm length, ideal for applications requiring full-length holding power.
  • Lightweight yet durable nylon material reduces overall assembly weight while providing excellent electrical insulation properties.

Professional Applications & Engineering Value

Engineered for demanding environments, these M6 hex head screws deliver exceptional value in applications where metal fasteners fail. The black nylon plastic construction inherently resists corrosion, chemicals, and electrical conductivity, making them ideal for electrical enclosures, marine equipment, and food processing machinery. With a Class 6g metric thread and coarse 1 mm pitch, installation is swift and secure, minimizing assembly errors in high-volume production. The fully threaded design ensures uniform stress distribution, while the external hex drive accommodates standard wrenches for reliable torque transmission. These screws excel in temperature-fluctuating settings, from automotive components to outdoor structures, providing long-term reliability without galvanic corrosion concerns.

Specification Summary & Compliance

This metric hex head screw features M6 x 1 mm thread size with Class 6g thread fit per ISO metric standards, ensuring precise dimensional accuracy. The 16 mm length and fully threaded configuration adhere to consistent manufacturing tolerances. Compliance with RoHS 3 (2015/863/EU) confirms the use of hazardous substance-free materials, supporting sustainable procurement practices in industrial supply chains.
