Key Features & Benefits at a Glance
- Exceptional durability and strength with Class 8.8 alloy steel construction, providing reliable performance under high-stress conditions.
- Precise and secure fastening thanks to the M8 coarse thread with 1.25mm pitch and Class 6g thread fit, ensuring consistent engagement and vibration resistance.
- Space-saving low-profile socket head allows installation in tight spaces while offering easy drive access with a standard 5mm hex key.
- Optimized load distribution through the partially threaded design, reducing thread wear and improving clamping force in assembled components.
- High corrosion resistance and environmental compliance with RoHS 3 and REACH standards, making it suitable for regulated industrial applications.
- Superior mechanical properties including 110,000 psi tensile strength and Rockwell C20 hardness for long-term reliability in demanding environments.
- Standardized dimensions per DIN 7984 ensure interchangeability and ease of integration with existing metric fastener systems.
Professional Applications & Engineering Value
This M8 socket head cap screw is engineered to address critical challenges in industrial machinery, automotive assemblies, and precision equipment. Made from Class 8.8 alloy steel, it delivers high tensile strength and hardness, preventing failure under dynamic loads and vibration. The low-profile socket head with a 5mm hex drive enables secure tightening in confined spaces, while the partially threaded and right-hand metric thread design ensures optimal stress distribution and reduces the risk of cross-threading. Compliant with DIN 7984, it offers reliable performance in applications requiring high-strength fasteners with consistent dimensional accuracy.
Specification Summary & Compliance
This screw features a Class 6g thread fit with M8 x 1.25mm coarse threads and a minimum thread length of 22mm, ensuring precise tolerance adherence. It meets DIN 7984 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, supporting safe and sustainable industrial use.
