Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these Class 12.9 steel hex head screws deliver critical reliability in machinery assembly, structural frameworks, and high-vibration equipment. The M12 coarse thread with 1.75mm pitch maintains secure fastening under dynamic loads, while the fully threaded design maximizes clamping force across the entire 35mm length. The external hex drive and 19mm head accommodate high-torque tools, speeding up installation in confined spaces. Ideal for automotive, construction, and manufacturing sectors where precision Class 6g threads prevent assembly errors and reduce maintenance downtime.
Specification Summary & Compliance
Manufactured to ISO 4017/DIN 933 specifications with Class 6g thread tolerance for dimensional accuracy. The metric coarse thread (M12 x 1.75mm) and 35mm length adhere to standardized measurements. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The Class 12.9 strength grade confirms consistent mechanical properties as per international fastener standards.
