Key Features & Benefits at a Glance

  • Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and chemical exposure.
  • Enhanced load distribution and vibration resistance thanks to the integrated flange, eliminating the need for a separate washer.
  • High tensile strength of 75,000 psi and Rockwell B83 hardness for reliable performance in demanding mechanical applications.
  • Secure and efficient installation with a 4mm hex drive, providing positive torque transmission and reducing the risk of stripping.
  • Wide, low-profile rounded button head offers a finished appearance and reduces the risk of snagging.
  • Precision Class 6g thread fit ensures consistent, reliable engagement with mating components for a secure assembly.
  • Full compliance with RoHS 3 and REACH regulations for safe use in sensitive and regulated industries.

Professional Applications & Engineering Value

This M6 x 1mm metric screw is engineered from 316 stainless steel, providing exceptional corrosion resistance that is critical for applications in marine, chemical processing, and food-grade equipment. The combination of a flanged hex button head and a coarse thread pitch solves common assembly challenges. The flange acts as an integrated washer, distributing clamp load over a wider area to prevent surface damage and combat loosening under vibration. The 4mm hex drive and low-profile head allow for installation in confined spaces where a standard socket head might not fit, making these industrial screws a versatile and durable fastener solution for machinery, enclosures, and structural frameworks.

Specification Summary & Compliance

This fastener features an M6 thread size with a 1mm coarse pitch and a Class 6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. It is fully threaded with a right-hand thread direction and measures 40mm in length. The manufacturing and material composition are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
