Professional Applications & Engineering Value
These high-strength socket head cap screws deliver critical performance where reliability under extreme loads is paramount. The black-oxide alloy steel construction provides superior protection against corrosion while maintaining the Class 12.9 mechanical properties essential for heavy machinery, automotive assemblies, and precision equipment. The M5 metric thread with 0.8mm pitch offers optimal engagement in both metals and engineered plastics, while the hex socket drive enables high torque application in confined spaces. Engineered to withstand vibration and shock loads, these fully threaded fasteners ensure consistent clamping force across the entire 50mm length, preventing joint failure in critical applications from robotics to industrial manufacturing.
Specification Summary & Compliance
This socket head cap screw features M5x0.8mm coarse metric thread with Class 5g6g thread fit tolerance according to ISO standards. Manufacturing complies with DIN 912/ISO 4762 specifications for dimensional accuracy and mechanical properties. The fastener meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations for environmental and safety standards, ensuring suitability for global industrial applications requiring certified components.
