Professional Applications & Engineering Value
Engineered for high-stress industrial applications, these M12 hex head screws solve critical fastening challenges where vibration resistance and structural integrity are paramount. The Class 10.9 steel construction provides exceptional fatigue resistance, preventing failure in machinery, structural frameworks, and heavy equipment. The fully threaded metric coarse pitch design ensures maximum thread contact in both metallic and composite materials, eliminating loosening in dynamic environments. With ISO 4017 compliance and external hex drive configuration, these screws deliver reliable performance in automotive assemblies, industrial machinery, and construction projects where precise torque application and consistent clamping force are essential for operational safety.
Specification Summary & Compliance
Manufactured to ISO 4017 specifications (equivalent to DIN 933) with Class 6g thread tolerance ensuring precise fit. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The metric coarse thread (M12 x 1.75mm) with right-hand direction and 20mm length provides standardized dimensional accuracy across industrial applications.
