- Precise Class 5g6g thread fit guarantees smooth assembly and secure fastening, reducing installation time and improving joint reliability.
- Partially threaded design allows for controlled clamping force and easier alignment in assemblies, enhancing overall structural stability.
- Standard hex drive (5mm) enables easy installation with common tools, speeding up maintenance and reducing labor costs.
- Compliance with DIN 912/ISO 4762 standards ensures interchangeability and consistent quality, supporting global engineering specifications.
Professional Applications & Engineering Value
This M6 socket head cap screw is engineered for heavy-duty industrial applications where reliability and strength are critical. The Class 12.9 alloy steel construction, combined with a black-oxide surface treatment, provides robust resistance to corrosion and wear, addressing common failures in machinery, automotive, and construction assemblies. Its coarse metric thread (1mm pitch) and partially threaded rod design facilitate quick installation and secure clamping in high-vibration environments, reducing maintenance downtime. Ideal for use in precision equipment, structural frames, and automated systems, this hex drive fastener delivers consistent performance under high tensile stress, ensuring long-term operational safety and efficiency.
Specification Summary & Compliance
The screw features a thread fit of Class 5g6g per ISO metric standards, ensuring dimensional accuracy and compatibility. It is manufactured in accordance with DIN 912 and ISO 4762 specifications for socket head cap screws, guaranteeing consistent quality and performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms the product is free from hazardous substances, supporting safe and sustainable industrial use.
