- Enhanced installation efficiency with coarse 1.75mm thread pitch providing faster assembly and reduced cross-threading risk
- Increased stability and distribution through the integrated flange design that eliminates the need for separate washers
- Optimized torque transmission with external hex drive and standard 18mm head width for secure tool engagement
- Precision thread fit with Class 6g tolerance ensuring consistent performance and compatibility with standard metric nuts
- Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe industrial use
Professional Applications & Engineering Value
These M12 hex head screws deliver critical engineering solutions where vibration resistance and structural integrity are paramount. The black-phosphate steel construction provides superior corrosion protection in harsh environments, while the Class 10.9 strength rating ensures reliable performance under heavy loads. The partially threaded design with coarse 1.75mm pitch offers optimal clamping force distribution, making them ideal for construction, heavy machinery, and industrial equipment assembly. The integrated flange provides wider bearing surface, reducing surface pressure and preventing loosening under dynamic loads. These metric coarse thread screws are engineered to withstand extreme conditions while maintaining precise Class 6g thread fit for consistent performance across applications.
Specification Summary & Compliance
Manufactured to ASME B18.2.3M and SAE J1199 specifications with Class 6g thread tolerance for precision fit. The 60mm length with 30mm minimum thread length and 26.6mm flange diameter ensures proper engagement and load distribution. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest industry standards for safe industrial use.
