S-91306A658 M3 x 12 mm ISO 7380 Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure
• Superior corrosion resistance from zinc plating protects against environmental degradation, extending service life in demanding conditions
• Precision Class 6g thread fit guarantees smooth installation and secure fastening with consistent engagement in mating components
• High hardness rating (Rockwell C32) provides excellent wear resistance, maintaining thread integrity through repeated assembly cycles
• Convenient 2 mm hex drive enables efficient installation with standard tools, reducing assembly time and labor costs
• Fully threaded design offers maximum grip length and adjustment flexibility across the entire fastener length
• Rounded button head profile provides a low-profile finish that minimizes snagging while offering attractive aesthetics

Professional Applications & Engineering Value

These M3 metric hex screws with Class 10.9 strength rating deliver critical performance advantages for industrial assemblies requiring both precision and durability. The zinc-plated alloy steel construction addresses common corrosion challenges in manufacturing environments, while the coarse thread pitch (0.5 mm) ensures rapid installation without compromising holding power. The rounded button head design with 2 mm hex drive provides optimal torque transmission for secure fastening in confined spaces. Engineers specify these fully threaded fasteners for machinery, automotive components, and electronic enclosures where vibration resistance and long-term reliability are paramount. The combination of 140,000 psi tensile strength and Rockwell C32 hardness makes these screws ideal for applications subject to dynamic loads and thermal cycling.
