S-90909A730 M6 x 25 mm ISO 7380 Stainless Steel Flanged Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction with passivated finish
• Enhanced load distribution and stability from the integrated flange, eliminating the need for separate washers
• High-strength performance with 70,000 psi tensile strength for reliable fastening in demanding applications
• Quick and secure installation using a standard 4 mm hex drive, providing excellent torque transfer
• Precise thread engagement with Class 6g fit and M6x1 mm coarse thread for easy alignment and robust connections
• Streamlined, low-profile design with a rounded button head that reduces snagging and improves safety
• Full regulatory compliance meeting ISO 7380, RoHS 3, and REACH for global industrial use

Professional Applications & Engineering Value

Engineered for challenging conditions, these M6 metric screws in 316 stainless steel deliver exceptional durability where moisture, chemicals, or salt exposure are concerns. The passivated finish enhances surface protection, significantly extending service life in marine, chemical processing, and food industry equipment. The flanged button head design combines a sleek appearance with functional benefits—the flange distributes clamping force over a wider area (13.6 mm diameter), reducing surface pressure and preventing loosening under vibration. With a coarse thread (1 mm pitch) and Class 6g thread fit, installation is faster and less prone to cross-threading, even in blind holes. Fully threaded for consistent grip along the entire 25 mm length, these screws are ideal for securing panels, machinery guards, and structural components where reliability and corrosion resistance are non-negotiable.
