Key Features & Benefits at a Glance

  • Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
  • Enhanced load distribution thanks to the integrated flange, reducing surface pressure and preventing loosening.
  • Secure, non-slip fastening from the serrated locking feature under the head, maintaining clamp force under vibration.
  • High mechanical strength with a tensile strength of 100,000 psi and Rockwell B100 hardness for demanding applications.
  • Precise and reliable fit ensured by the Class 6g thread tolerance, providing consistent performance in metric assemblies.
  • Efficient installation and removal with the standard external hex drive, compatible with common tools.
  • Full regulatory compliance with RoHS 3 and REACH, ensuring safety and environmental standards are met.

Professional Applications & Engineering Value

This M10x1.5 flanged hex head screw is engineered to solve critical challenges in industrial fastening. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, making it perfect for outdoor machinery, chemical processing equipment, and marine applications. The coarse thread and Class 6g thread fit ensure quick assembly and a secure hold in various materials, reducing the risk of cross-threading. The flange design eliminates the need for a separate washer, distributing clamp load evenly to prevent damage to soft surfaces and providing a larger bearing area. Combined with serrations for vibration resistance, this screw delivers reliable performance in high-stress environments like automotive assemblies, structural frameworks, and heavy-duty manufacturing, where failure is not an option.

Specification Summary & Compliance

This screw features a Metric M10x1.5 coarse thread with a Class 6g thread fit for precise dimensional accuracy. It is fully threaded and manufactured from 18-8 stainless steel, meeting common industrial standards for hex head screws. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in various global markets.
