Professional Applications & Engineering Value
This M4 flanged button head screw delivers exceptional engineering value in demanding industrial settings. Manufactured from 18-8 Stainless Steel with a passivated finish, it provides excellent resistance to oxidation, chemicals, and moisture, making it ideal for machinery, automotive assemblies, and outdoor equipment. The flanged design distributes clamping force over a wider area, reducing surface pressure and preventing loosening under vibration. Combined with a Class 6g coarse thread and fully threaded shank, it ensures rapid installation and secure fastening in metals, plastics, and composite materials. These features solve common pain points like corrosion-induced failure, assembly time, and maintenance frequency, offering a durable, high-performance metric fastener solution.
Specification Summary & Compliance
This screw maintains ISO 7380 dimensional standards with M4 x 0.7mm coarse pitch threads and Class 6g tolerance for consistent fit. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances. The manufacturing adheres to specified metrics: 12mm length, 9.4mm flange diameter, and right-hand threading, providing reliable performance for industrial and engineering applications.
