Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide coating extends service life in harsh industrial environments.
- High hardness (Rockwell C37) provides excellent wear resistance, maintaining thread integrity over repeated use.
- Precision Class 5g6g thread fit offers consistent engagement and reduces the likelihood of cross-threading during assembly.
- Partially threaded design allows for secure clamping where only a specific section requires threading, improving versatility.
- 5 mm hex drive with standard socket head enables easy installation and high torque application with common tools.
- Compliance with DIN 912/ISO 4762 ensures dimensional accuracy and interchangeability with other standard components.
Professional Applications & Engineering Value
These M6 socket head cap screws are engineered for demanding applications where reliability under high stress is critical. Made from Class 12.9 alloy steel, they provide superior strength and fatigue resistance, making them ideal for machinery, automotive assemblies, and heavy equipment. The black-oxide surface treatment enhances corrosion protection without sacrificing dimensional tolerances, while the coarse metric thread (1 mm pitch) ensures quick assembly and robust holding power. Their partially threaded rod type allows precise placement in structural joints, reducing weight and material use without compromising safety. These screws meet rigorous DIN 912/ISO 4762 standards, offering consistent performance in industrial settings that require durable, precision metric fasteners.
Specification Summary & Compliance
This product features a Class 5g6g thread fit per metric standards, ensuring precise dimensional accuracy for reliable fastening. It complies with DIN 912/ISO 4762 specifications for socket head cap screws, covering dimensions and mechanical properties. Additionally, it is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, confirming adherence to environmental and safety regulations for hazardous substances.
