S-98093A224 M10 x 18 mm ISO 898-1, DIN 6921 High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 150,000 psi ensures reliable performance under extreme loads, reducing the risk of fastener failure in demanding applications.
• High-strength Class 10.9 rating provides superior clamping force and fatigue resistance, ideal for critical structural and machinery assemblies.
• Black-phosphate steel construction offers excellent corrosion resistance, extending service life in harsh industrial environments.
• Integrated flange design eliminates the need for a separate washer, simplifying installation and providing a larger bearing surface for improved joint stability.
• Fully threaded M10x1.5 coarse thread with Class 6g fit ensures easy alignment and secure fastening, even in high-vibration settings.
• External hex drive and hex head allow for high-torque application with standard tools, speeding up assembly and maintenance processes.
• Compliance with ISO 898-1 and DIN 6921 standards guarantees consistent quality, dimensional accuracy, and interchangeability for global engineering projects.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this M10 hex head flange screw addresses common challenges like joint loosening and material fatigue. The black-phosphate steel provides a durable, corrosion-resistant finish that withstands exposure to oils, moisture, and varying temperatures, making it suitable for automotive chassis, construction equipment, and machinery frames. The Class 10.9 strength grade and Rockwell C32 hardness ensure the fastener maintains integrity under dynamic loads and vibrations, while the fully threaded coarse pitch design allows for quick installation and robust clamping in thick materials. By integrating a flange, it distributes pressure evenly, reducing surface damage and enhancing the reliability of assembled structures in sectors requiring high tensile strength bolts and long-term performance.
