Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh chemical and marine environments
- Enhanced durability and load distribution thanks to the integrated flange design, eliminating the need for a separate washer
- High-strength performance with a tensile strength of 70,000 PSI for reliable fastening in demanding applications
- Secure and efficient installation with a 3 mm hex drive, providing excellent torque transfer and reducing the risk of stripping
- Optimized thread engagement with a coarse 0.8 mm pitch and Class 6g fit, ensuring quick assembly and vibration resistance
- Improved surface protection from a passivated finish, which enhances the natural corrosion resistance of the stainless steel
- Full regulatory compliance with ISO 7380, RoHS 3, and REACH, guaranteeing safety and environmental standards for global supply chains
Professional Applications & Engineering Value
This M5 flanged hex button head screw is engineered to solve critical challenges in industrial assembly. The 316 stainless steel material offers exceptional pitting and crevice corrosion resistance, making it a top choice for applications in chemical processing, marine equipment, and food machinery where exposure to corrosive agents is a constant threat. The integrated flange provides a larger bearing surface, which helps prevent surface damage and loosening under vibration, a common failure point in machinery and structural frames. Combined with the coarse metric thread and fully threaded design, it ensures rapid installation and reliable clamping force, reducing assembly time and maintenance costs in high-volume production environments.
Specification Summary & Compliance
This screw adheres to precise dimensional standards with a Class 6g thread fit as per ISO 7380, ensuring consistent interchangeability. The manufacturing and material specifications are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting sustainable procurement practices.
