Professional Applications & Engineering Value

This M6 x 1 mm flanged hex button head screw is engineered from 316 stainless steel to solve critical challenges in corrosive or high-moisture environments, such as marine equipment, chemical processing plants, and outdoor machinery. The passivated finish enhances the material's natural resistance, preventing rust and extending service life. Its flanged design acts as an integrated washer, reducing part count and assembly time while providing a larger bearing surface to prevent surface damage and loosening under vibration. The low-profile rounded head and 4 mm hex drive enable secure fastening in tight spaces where clearance is limited, making it ideal for compact enclosures, machinery frames, and precision instruments. Fully threaded with a Class 6g coarse thread, it offers quick installation and reliable holding power in various substrates, ensuring your assemblies remain robust and maintenance-free.

Specification Summary & Compliance
