  • Effortless installation and removal via the 2.5 mm internal hex drive, designed for secure tool engagement and reduced slippage.
  • Enhanced load distribution and vibration resistance thanks to the integrated 9.4 mm flange, eliminating the need for a separate washer.
  • Precise, reliable threading with Class 6g coarse thread (M4 x 0.7mm), ensuring consistent fit and reduced cross-threading risk.
  • Streamlined, low-profile design with a rounded button head, ideal for applications where clearance is limited.
  • Global compliance and safety meeting ISO 7380, RoHS 3, and REACH standards for assured quality and environmental responsibility.

Professional Applications & Engineering Value

This M4 flanged hex button head screw is engineered to address critical fastening challenges in industrial settings. The 18-8 stainless steel construction, combined with a passivated finish, provides exceptional resistance to oxidation and chemical exposure, making it ideal for machinery, automotive assemblies, and electronic enclosures operating in demanding conditions. The fully threaded design and coarse thread pitch enable rapid installation and high clamping force, while the integral flange distributes stress over a wider area, preventing surface damage and loosening under vibration. Compliant with ISO 7380, this screw ensures dimensional accuracy and interchangeability, reducing assembly time and maintenance costs for engineers and OEMs.

Specification Summary & Compliance

This metric screw features an M4 x 0.7 mm coarse thread with a Class 6g tolerance for precise fit. It is manufactured in accordance with ISO 7380 specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global supply chains and restricted substance requirements.
