S-96660A209 M5 x 8 mm ISO 7380-2 Steel Flanged Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 100,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in demanding applications.
• Superior corrosion resistance from zinc plating protects against rust and environmental damage, extending service life in harsh industrial settings.
• High hardness rating of Rockwell C32 provides excellent wear resistance, maintaining thread integrity and reducing wear over repeated use.
• Efficient torque transmission with a 3 mm hex drive allows for quick installation and secure fastening, minimizing assembly time and tool slippage.
• Wide flange design distributes clamping force evenly, preventing surface damage and improving joint stability without needing a separate washer.
• Coarse thread pitch enables faster driving and better grip in soft materials, enhancing assembly speed and reducing cross-threading risks.
• Full threading along the 8 mm length ensures maximum engagement and holding power, ideal for applications requiring strong, uniform fastening.

Professional Applications & Engineering Value
