S-97654A385 M8 x 25 mm ISO 7380 Stainless Steel Flanged Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance thanks to 18-8 Stainless Steel construction and a passivated finish, ensuring long-term reliability in harsh environments.
• High mechanical strength and durability with a tensile strength of 70,000 PSI and Rockwell B70 hardness, preventing failure under heavy loads.
• Secure and efficient installation enabled by the 5mm hex drive and flanged design, which eliminates the need for a separate washer and provides superior torque transmission.
• Reliable thread engagement with a Class 6g fit and coarse M8 x 1.25mm thread, offering excellent vibration resistance and faster assembly.
• Wide-bearing surface from the rounded button head and integrated flange, distributing clamp load effectively and protecting assembled surfaces.
• Full threading for maximum grip along the entire 25mm length, providing consistent holding power across the entire fastened joint.
• Guaranteed quality and safety through compliance with ISO 7380, RoHS 3, and REACH standards, ensuring international specification adherence and material safety.

Professional Applications & Engineering Value

This M8 rounded head screw is engineered to solve critical challenges in industrial assembly and machinery. The 18-8 Stainless Steel material, combined with a passivated finish, provides superior resistance to oxidation and chemical exposure, making it ideal for applications in food processing, marine equipment, and outdoor machinery where moisture is a concern. The flanged design and coarse thread (M8 x 1.25mm) ensure a secure, vibration-resistant fastening in materials like aluminum and castings, preventing loosening in high-stress environments. The hex drive allows for high-torque installation with standard tools, speeding up assembly lines while the fully threaded body maximizes adjustability and clamp force in demanding structural applications.
