- Superior corrosion resistance from the black-oxide finish prolongs service life in harsh industrial environments, minimizing maintenance needs.
- High hardness rating of Rockwell C44 provides excellent wear resistance, maintaining thread integrity through repeated use.
- Precise Class 5g6g thread fit guarantees smooth installation and secure fastening in metric assemblies.
- Standard hex socket drive with 5mm key size allows for easy installation in confined spaces with common tools.
- Partially threaded design offers optimal grip length control for specific clamping requirements.
- Compliance with DIN 912 standards ensures dimensional accuracy and interchangeability with other metric components.
Professional Applications & Engineering Value
Engineered for demanding industrial environments, these Class 12.9 socket head cap screws deliver exceptional performance where failure is not an option. The black-oxide alloy steel construction provides superior protection against corrosion while maintaining the high tensile strength required for heavy machinery, automotive assemblies, and precision equipment. The M6 x 1mm coarse thread configuration ensures rapid installation and reliable holding power in high-vibration applications. With 24mm minimum thread length and partially threaded design, these fasteners offer precise clamping force distribution, making them ideal for structural components, manufacturing jigs, and industrial automation systems where dimensional stability and repeatability are critical.
Specification Summary & Compliance
This metric socket head cap screw features M6 x 1mm coarse threads with Class 5g6g thread fit tolerance per ISO standards. Manufactured to DIN 912 specifications for dimensional accuracy, it meets Class 12.9 strength requirements with 170,000 psi tensile strength and Rockwell C44 hardness. The product is RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, ensuring environmental safety and regulatory adherence for global industrial applications.
