Key Features & Benefits at a Glance
- Exceptional tensile strength with Class 10.9 rating (150,000 PSI) ensures reliable performance in high-stress industrial applications.
- Superior corrosion resistance from blue-dyed zinc plating extends service life in harsh environments.
- High hardness (Rockwell C32) provides excellent wear resistance and reduces thread deformation during installation.
- Precise Class 6g thread fit guarantees smooth assembly and secure fastening with standard M6 nuts.
- Fully threaded design offers consistent clamping force along the entire 20mm length for uniform load distribution.
- External hex drive compatibility enables quick installation with common wrench tools, reducing assembly time.
- Compliance with ISO 4017 (DIN 933) ensures international interchangeability and quality consistency.
Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M6 hex head screws combine Class 10.9 high-strength steel with blue-dyed zinc plating to solve critical fastening challenges. The coarse 1mm pitch thread provides superior resistance to vibration loosening in heavy machinery, automotive assemblies, and structural frameworks. With fully threaded construction and Class 6g tolerance, they maintain consistent preload across mating surfaces while the external hex drive facilitates rapid installation in confined spaces. This combination of high tensile strength and corrosion-resistant finish makes them ideal for applications requiring both mechanical reliability and environmental durability.
Specification Summary & Compliance
Manufactured to ISO 4017 (DIN 933) specifications with Class 6g thread fit tolerance for precise engagement. The M6 x 1mm coarse thread maintains standard metric dimensions while the 20mm length provides versatile fastening capability. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across international markets.
