Professional Applications & Engineering Value
Engineered for industrial machinery, automotive assemblies, and precision equipment, these Class 10.9 metric hex socket screws deliver critical reliability where vibration resistance and structural integrity matter most. The zinc-plated alloy steel construction provides essential corrosion protection in manufacturing environments, while the fully threaded M4 coarse pitch design ensures rapid installation and superior pull-out resistance. The rounded button head profile offers clean aesthetics and reduced protrusion in confined spaces. With 140,000 psi tensile strength and controlled Rockwell C32 hardness, these hex drive screws maintain clamping force under dynamic loads, preventing joint failure in critical applications.
Specification Summary & Compliance
Manufactured to ISO 7380 standards with Class 6g thread fit tolerance for precise mating components. The M4 x 0.7mm coarse thread configuration ensures compatibility with standard metric assemblies. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe use across regulated industries. The 10mm length with fully threaded design provides consistent engagement depth for uniform load distribution.
