Key Features & Benefits at a Glance

  • Exceptional corrosion resistance from black nylon plastic construction, eliminating rust and chemical degradation in harsh environments
  • Superior electrical insulation properties for safe use in electrical assemblies and sensitive electronic applications
  • Wide temperature tolerance from -40° to 185°F (-40° to 85°C) ensures reliable performance across diverse operating conditions
  • Precision Class 6g thread fit provides consistent engagement and secure fastening in metric applications
  • External hex drive design enables high-torque installation with standard tools for efficient assembly
  • RoHS 3 compliance meets environmental regulations for restricted substances in industrial applications
  • Coarse 1.75mm thread pitch facilitates quick installation and reduces cross-threading risks

Professional Applications & Engineering Value

Our M12 nylon hex head screws deliver critical engineering advantages where metal fasteners fail. The black nylon plastic construction provides inherent corrosion resistance, making these metric fasteners ideal for chemical processing, marine, and outdoor applications where moisture and corrosive agents are present. The material's natural electrical insulation properties prevent current conduction, ensuring safety in electrical enclosures, control panels, and electronic assemblies. With fully threaded design and Class 6g threading, these screws maintain consistent clamping force across the entire 25mm length, while the coarse 1.75mm pitch enables rapid installation in production environments. The external hex drive accommodates high torque applications without stripping, and the temperature stability from -40° to 185°F ensures dimensional integrity across seasonal variations.

Specification Summary & Compliance

This M12 x 1.75mm metric screw features precision Class 6g thread fit according to ISO metric standards, ensuring compatibility with standard metric coarse thread applications. The fully threaded design provides consistent engagement across the entire 25mm length. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, guaranteeing environmental compliance for industrial use. The external hex drive with 18mm head width and 9mm head height accommodates standard metric wrench sizes for reliable installation.
