• Enhanced load distribution and vibration resistance thanks to the integrated flange, eliminating the need for a separate washer.
• Secure and efficient installation with a 4 mm hex drive and button head design, providing a flush finish and high torque capability.
• Reliable coarse thread (M6x1mm) with Class 6g fit ensures quick assembly and strong holding power in a wide range of materials.
• Full threading along the 20 mm length offers maximum grip and adjustability in deep or variable thickness applications.
• High tensile strength of 70,000 psi provides dependable performance under significant mechanical stress.
• Global compliance and quality assurance with ISO 7380 standards, RoHS 3, and REACH, ensuring safety and environmental responsibility.

Professional Applications & Engineering Value

This M6 flanged button head screw is engineered to solve critical challenges in industrial assembly, particularly where corrosion resistance and space constraints are paramount. The use of 316 stainless steel and a passivated finish provides exceptional protection against rust and chemical degradation, making it ideal for marine, chemical processing, and food-grade equipment. The flanged design increases the bearing surface, distributing clamp load effectively to prevent surface damage and loosening under vibration—common in machinery and automotive applications. The hex button head allows for a low-profile, aesthetically clean installation with a standard 4 mm hex key, ensuring high torque transfer without slippage. Its fully threaded coarse metric thread ensures rapid, secure fastening in metals and plastics, enhancing assembly speed and reliability in production lines.
