Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide finish on alloy steel prolongs service life in harsh or humid environments, minimizing maintenance needs.
- Precision thread fit (Class 5g6g) provides consistent engagement and vibration resistance, enhancing assembly stability and safety.
- High hardness (Rockwell C37) offers excellent wear resistance, maintaining thread integrity through repeated use and high torque.
- Standard hex drive (5mm) allows for easy installation with common tools, speeding up assembly and reducing labor time.
- Full threading and coarse pitch (1mm) enable quick fastening and strong holding power in a variety of materials, improving efficiency.
- Compliance with DIN 912/ISO 4762 ensures dimensional accuracy and interchangeability, supporting global engineering standards and quality assurance.
Professional Applications & Engineering Value
Engineered for demanding environments, this M6 socket head cap screw combines black-oxide alloy steel and a Class 12.9 strength rating to address critical industrial challenges like vibration loosening and corrosion-induced failures. The fully threaded design with coarse metric threads ensures rapid installation and robust clamping force in machinery, automotive, and heavy equipment assemblies. Its high tensile strength and precise hex drive make it ideal for applications requiring reliable fastening under dynamic loads, while the corrosion-resistant coating extends lifespan in outdoor or chemically exposed settings, reducing downtime and replacement costs.
Specification Summary & Compliance
This fastener adheres to DIN 912 / ISO 4762 standards for dimensional accuracy, including a Class 5g6g thread fit and coarse thread spacing. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for environmental safety, ensuring no hazardous substances are used. Manufactured to precise specifications, it guarantees consistent performance in industrial applications requiring high-strength, metric-threaded fasteners.
