Key Features & Benefits at a Glance

  • Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh or marine environments.
  • Simplified installation and increased clamping force thanks to the integrated flange, eliminating the need for a separate washer.
  • Secure, high-torque driving enabled by the 4 mm internal hex drive, reducing the risk of tool slippage and head stripping.
  • Reliable thread engagement and consistent performance ensured by the Class 6g precision thread fit and M6x1 mm coarse thread profile.
  • High mechanical strength and durability with a tensile strength of 75,000 psi and a hardness of Rockwell B83 for demanding applications.
  • Streamlined, low-profile design from the rounded button head, providing a finished look while minimizing protrusion.
  • Guaranteed material safety and environmental compliance by meeting RoHS 3 and REACH regulations.

Professional Applications & Engineering Value

This M6 flanged button head screw is engineered to solve critical challenges in industrial assembly. The 316 stainless steel material offers superior resistance to chemicals and saltwater, making it a top choice for marine equipment, food processing machinery, and outdoor structures. The integrated flange distributes clamping force over a wider area (16.7 mm diameter), preventing surface damage and maintaining joint integrity under vibration. Combined with the Class 6g coarse thread, it ensures rapid installation and robust holding power in metals and plastics. The 4 mm hex drive allows for high-torque application, making it a reliable metric fastener for maintenance, fabrication, and OEM production lines where corrosion and strength are primary concerns.

Specification Summary & Compliance

This fully threaded screw features an M6 x 1 mm coarse metric thread with a Class 6g tolerance for precise fit. It is manufactured from 316 stainless steel, heat treated to a hardness of Rockwell B83, and delivers a tensile strength of 75,000 psi. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for industrial use.
