Professional Applications & Engineering Value

This M10 hex head screw is engineered to address critical challenges in industrial and mechanical assemblies where vibration loosening, corrosion, and high tensile demands are prevalent. The extra fine metric thread (M10x1.0) and Class 8.8 strength grade deliver exceptional clamp load retention and fatigue resistance, making it ideal for machinery, automotive subsystems, and structural frameworks. The zinc-plated steel finish combats moisture and chemical exposure, while the partially threaded design concentrates stress away from the thread roots, minimizing failure risks. With its external hex drive and precise Class 6h thread fit, this fastener supports efficient maintenance and aligns with ISO 8765 DIN 960 standards for consistent quality in OEM and MRO applications.

Specification Summary & Compliance

This fastener features an M10x1.0 extra fine thread with a Class 6h thread fit and partial threading over a 26 mm minimum thread length. It complies with ISO 8765 DIN 960 manufacturing specifications and is certified RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to environmental and safety regulations. The Class 8.8 strength grade corresponds to a tensile strength of 110,000 psi and Rockwell C21 hardness, confirming its suitability for high-performance, regulated industrial use.
