• Global compatibility through ISO 4014 (DIN 931) certification for international project specifications

Professional Applications & Engineering Value

This M12 hex head screw delivers critical engineering solutions for industrial assembly challenges where vibration resistance and structural integrity are paramount. The Class 10.9 steel construction provides exceptional load-bearing capacity, making it ideal for heavy machinery, structural steel connections, and automotive applications. The metric coarse thread with 1.75mm pitch offers superior engagement in various materials while the zinc yellow-chromate plating creates a protective barrier against corrosion in outdoor or chemically aggressive environments. The partially threaded design concentrates strength where needed most, preventing thread damage during installation while maintaining clamping force. These industrial fasteners are engineered to withstand dynamic loads and thermal cycling, ensuring long-term reliability in critical assemblies.

Specification Summary & Compliance

Manufactured to exact ISO 4014 specifications (equivalent to DIN 931) with Class 6h thread fit tolerance for precision engagement. The metric coarse threading (M12 x 1.75mm) ensures compatibility with standard components while the 85mm length with 30mm minimum thread length provides versatile fastening options. Complies with international standards for dimensional accuracy and mechanical properties, meeting requirements for industrial machinery, construction, and automotive applications where reliable high-strength fastening is essential.
