S-91306A672 M6 x 16 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-plated alloy steel construction extends service life in harsh industrial environments.
• High hardness rating (Rockwell C32) provides excellent wear resistance and maintains thread integrity during repeated use.
• Precise Class 6g thread fit guarantees smooth installation and secure fastening with compatible metric nuts and tapped holes.
• Convenient 4mm hex drive allows for quick installation and removal with standard tools, improving assembly efficiency.
• Fully threaded design offers maximum grip length and adjustment flexibility across the entire fastener length.
• Compliance with international standards including ISO 7380 ensures dimensional accuracy and global interoperability.

Professional Applications & Engineering Value

These M6 metric screws with Class 10.9 strength rating and zinc-plated alloy steel construction are engineered to solve critical fastening challenges in demanding environments. The combination of 140,000 psi tensile strength and Rockwell C32 hardness prevents stripping and deformation under heavy loads, while the coarse 1mm pitch threading ensures rapid installation in production settings. The rounded button head with 4mm hex drive provides a clean aesthetic finish while allowing high torque application. Ideal for machinery assembly, automotive components, and structural frameworks where vibration resistance and long-term reliability are paramount. The fully threaded design maximizes contact surface area, distributing stress evenly across the entire fastener length for enhanced joint integrity.
