Key Features & Benefits at a Glance
- Exceptional load-bearing capability with Class 10.9 high-strength steel construction, supporting up to 150,000 psi tensile strength for demanding industrial applications
- Superior wear and deformation resistance thanks to Rockwell C32 hardness, ensuring long-term reliability under repeated stress
- Optimized coarse thread design (1.75mm pitch) provides faster installation and reduced cross-threading risk in heavy-duty assemblies
- Precise Class 6g thread fit guarantees consistent engagement and vibration resistance in metric fastener systems
- External hex drive with 19mm head delivers high torque transmission and easy access with standard tools
- Partial threading with 30mm minimum thread length allows secure clamping in thick materials while minimizing weight
- Full regulatory compliance including DIN 931 standards, RoHS 3, and REACH for global industrial acceptance
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this M12 hex head screw solves critical fastening challenges in machinery, structural steel, and equipment manufacturing. The Class 10.9 steel construction combined with 150,000 psi tensile strength prevents joint failure under extreme dynamic loads, while the coarse metric thread (1.75mm pitch) ensures rapid assembly in high-vibration environments. The partially threaded design concentrates clamping force precisely where needed, making it ideal for thick-section assemblies where full threading would compromise performance. With Rockwell C32 hardness and black surface finish, it maintains integrity in corrosive industrial settings while meeting international DIN 931 specifications for dimensional accuracy.
Specification Summary & Compliance
This M12 x 1.75mm coarse thread fastener features Class 6g thread tolerance for precise fit, 30mm minimum thread length, and 150mm total length with external hex drive. Manufacturing complies with DIN 931 standards for dimensional consistency and mechanical properties. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, ensuring environmental responsibility and global market acceptance for industrial fastener applications.
