S-90854A139 M6 x 25 mm ISO 4017, DIN 933 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capability with 150,000 PSI tensile strength for reliable performance in high-stress applications
• Superior corrosion resistance through zinc yellow-chromate plating that extends service life in harsh environments
• Precise torque transmission enabled by external hex drive design and Class 6h thread fit for secure fastening
• Optimized for heavy-duty applications with Class 10.9 strength grade and Rockwell C32 hardness
• Quick installation and removal with standard M6 coarse thread pitch and right-hand threading
• Full thread engagement along the 25mm length for maximum grip strength in assembled components
• Global compliance assurance meeting ISO 4017/DIN 933 standards and environmental regulations

Professional Applications & Engineering Value

These Class 10.9 hex head screws deliver critical reliability for industrial machinery, automotive assemblies, and structural frameworks where vibration resistance and sustained clamping force are paramount. The fully threaded M6x1mm coarse pitch design ensures maximum thread engagement in tapped holes or with nuts, while the zinc yellow-chromate plating creates a protective barrier against oxidation and chemical exposure. Engineered to ISO 4017/DIN 933 specifications, these metric steel fasteners maintain dimensional stability under extreme loads, preventing joint failure in heavy-duty applications. The external hex drive accommodates standard tools for efficient installation in confined spaces.
