Professional Applications & Engineering Value
This M4 flanged button head screw is engineered to address common challenges in machinery assembly, electronics, and automotive industries. The 18-8 stainless steel material, combined with a passivated finish, provides exceptional resistance to oxidation and chemical exposure, reducing maintenance costs in corrosive settings. Its flanged design distributes clamping force evenly, preventing surface damage and loosening under vibration. The coarse metric thread and Class 6g fit ensure quick, reliable fastening in high-volume production lines, while the hex drive enables efficient installation in confined spaces. By integrating durability with regulatory compliance, this screw minimizes downtime and enhances the longevity of critical assemblies.
Specification Summary & Compliance
This screw adheres to ISO 7380 standards for dimensional accuracy, featuring an M4 x 0.7mm coarse thread with a Class 6g tolerance for consistent performance. It is fully threaded for maximum grip and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. The manufacturing process follows strict guidelines for metric thread forms and material integrity, supporting reliable use in regulated industrial applications.
