Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in harsh or humid environments.
- Precise Class 6g thread fit and coarse 1.25mm pitch for quick, secure installation and vibration resistance in demanding assemblies.
- High hardness rating of Rockwell C37 provides excellent wear resistance, maintaining thread integrity over repeated use.
- Fully threaded M8 design allows for consistent clamping force along the entire 8mm length, ideal for compact spaces.
- Standard hex socket drive (6mm) enables easy installation with common tools, minimizing assembly time and effort.
- Compliance with DIN 912, ISO 4762, and ISO 898-1 guarantees dimensional accuracy and interoperability with metric components.
Professional Applications & Engineering Value
This M8 socket head cap screw is engineered for high-performance applications where reliability is critical. The black-oxide alloy steel construction offers enhanced corrosion protection, making it suitable for automotive, machinery, and outdoor equipment exposed to moisture or chemicals. With a Class 12.9 strength rating and coarse thread pitch, it provides superior clamping force and resists loosening under vibration, addressing common failure points in dynamic systems. The fully threaded design ensures uniform stress distribution, while the hex drive allows for precise torque application in confined spaces, streamlining maintenance and assembly processes in industrial settings.
Specification Summary & Compliance
This screw features an M8 x 1.25mm coarse thread with Class 6g tolerance for precise fit, manufactured to DIN 912, ISO 4762, and ISO 898-1 standards. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met.
