Key Features & Benefits at a Glance
- Exceptional load-bearing capability with Class 12.9 strength rating and 170,000 psi tensile strength for reliable performance in demanding applications
- Superior corrosion resistance provided by black-oxide coating, extending service life in harsh industrial environments
- Precise torque transmission through 12mm hex drive design, ensuring secure installation and preventing tool slippage
- Optimized thread engagement with M14x2mm coarse thread and Class 5g6g fit, facilitating quick assembly while maintaining vibration resistance
- Enhanced durability from Rockwell C37 hardness, resisting wear and deformation under heavy loads
- Versatile partial threading (40mm thread length on 75mm body) allowing both threaded and unthreaded section functionality
- Global compliance assurance meeting DIN 912/ISO 4762 standards for consistent quality and dimensional accuracy
Professional Applications & Engineering Value
These M14 socket head cap screws deliver critical engineering solutions for heavy machinery, automotive assemblies, and industrial equipment where high-strength fastening is paramount. The black-oxide alloy steel construction provides essential corrosion protection in environments exposed to moisture and chemicals, while the Class 12.9 strength rating ensures structural integrity under extreme vibrational and tensile loads. The metric coarse thread (M14x2mm) enables rapid installation in production lines, and the partially threaded design offers flexibility for applications requiring both clamping and alignment functions. The 12mm hex drive socket head profile guarantees secure tool engagement, preventing cam-out during high-torque installation in confined spaces typical of industrial machinery maintenance and manufacturing applications.
Specification Summary & Compliance
Manufactured to DIN 912/ISO 4762 specifications with Class 5g6g thread fit tolerance ensuring precise dimensional accuracy. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The right-hand coarse thread with 2mm pitch and 40mm minimum thread length maintains standard industrial threading conventions for compatibility across global applications.
