S-98093A215 M6 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 in high-stress industrial environments, reducing the risk of fastener failure.
• Superior corrosion resistance from the black-phosphate steel coating extends service life in harsh or outdoor applications, minimizing maintenance needs.
• High-strength Class 10.9 rating guarantees consistent load-bearing capacity and durability for critical assemblies.
• Integrated flange design eliminates the need for separate washers, simplifying installation and providing a larger bearing surface for secure fastening.
• Full threading along the 18mm length offers maximum grip and adjustability in a variety of material thicknesses.
• Precision external hex drive allows for high-torque application with standard tools, ensuring tight and secure installations.
• Compliance with international standards including ISO 898-1 and DIN 6921 ensures dimensional accuracy and interoperability in global projects.

Professional Applications & Engineering Value

Engineered for demanding environments, these M6 hex head screws in black-phosphate steel address common industrial challenges such as vibration loosening and environmental degradation. The Class 10.9 strength grade and Rockwell C32 hardness provide a robust solution for heavy machinery, automotive frames, and structural steelwork, where failure is not an option. The coarse thread (1mm pitch) and fully threaded design ensure quick assembly and strong holding power in both soft and hard materials. The flange distributes clamp load effectively, preventing surface damage and maintaining joint integrity under dynamic loads, making these screws ideal for industrial fastening applications requiring long-term reliability and corrosion resistance.
