S-91239A523 M10 x 45 mm ISO 7380 Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional Tensile Strength – With a 140,000 psi rating, these screws withstand heavy loads and high-stress conditions, ensuring long-term joint integrity in demanding applications.
• Superior Corrosion Resistance – The black-oxide finish on alloy steel provides enhanced protection against rust and environmental degradation, extending service life in harsh industrial settings.
• High Hardness for Wear Resistance – Rockwell C32 hardness minimizes wear and deformation during installation and use, maintaining fastener performance over repeated cycles.
• Precision Thread Fit – Class 6g thread tolerance ensures smooth, secure engagement with mating components, reducing the risk of cross-threading and improving assembly efficiency.
• Convenient Hex Drive Design – The 6mm hex drive allows for easy installation and removal with standard tools, speeding up assembly while providing reliable torque transmission.
• Full Threading for Maximum Grip – Fully threaded along the 45mm length, these screws offer consistent holding power across the entire engagement area, ideal for varied material thicknesses.
• Compliance with International Standards – Meets ISO 7380 specifications and environmental regulations (RoHS 3, REACH), ensuring quality, safety, and global acceptance for your projects.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M10 hex button head screws address critical challenges in machinery, automotive, and structural assemblies. The black-oxide alloy steel construction combats corrosion in humid or chemically aggressive environments, while the Class 10.9 strength grade and 140,000 psi tensile strength prevent failure under dynamic loads. The fully threaded metric coarse thread (1.5mm pitch) ensures rapid installation and robust clamping force, reducing vibration-induced loosening. With a rounded button head profile and 6mm hex drive, they provide a low-profile, secure fit that minimizes protrusion risks in compact spaces, enhancing both safety and aesthetics in professional setups.
