S-94559A735 M6 x 25 mm Aluminum Oversized-Flange Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Enhanced durability and corrosion resistance with 6061 Aluminum construction, ideal for demanding industrial environments
• Superior load distribution and vibration resistance thanks to the integrated flange design that eliminates the need for separate washers
• High-strength fastening performance with a tensile strength of 40,000 psi and Rockwell B40 hardness for reliable, long-lasting connections
• Effortless installation and removal using a standard 4 mm hex key, providing a secure, slip-resistant drive
• Precise and reliable thread engagement with a Class 6g coarse pitch (M6 x 1 mm), ensuring consistent performance and easy alignment
• Streamlined, low-profile design from the rounded button head, reducing snagging and improving aesthetics in finished products
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global markets

Professional Applications & Engineering Value

This M6 flanged button head screw is engineered to solve common fastening challenges in machinery, electronics, and structural assemblies. The 6061 Aluminum body offers an excellent strength-to-weight ratio, resisting corrosion where steel fasteners would fail. The fully threaded Class 6g design with a coarse pitch provides rapid installation and robust holding power, even in materials prone to stripping. The integrated flange distributes clamping force over a wider area (20.3 mm diameter), preventing surface damage and loosening under vibration—a critical advantage in industrial applications like automotive fixtures, conveyor systems, and panel mounting. Combined with the low-profile hex socket button head, it delivers a flush, secure finish that meets both functional and aesthetic demands in professional settings.
