Professional Applications & Engineering Value
Engineered for demanding industrial applications, this M4 socket head cap screw combines zinc-flake-coated alloy steel with a Class 12.9 strength rating to address critical challenges like vibration loosening and environmental degradation. The coarse thread metric design (M4 x 0.7mm) facilitates rapid installation in machinery, automotive components, and precision equipment, while the hex drive socket and 3mm drive size enable high torque transfer without slippage. Its fully threaded construction ensures uniform stress distribution, reducing the risk of joint failure in dynamic loads. Ideal for OEM and MRO use, this fastener delivers long-term reliability in corrosive or high-stress environments, supported by rigorous testing and material excellence.
Specification Summary & Compliance
This product features precise Class 5g6g thread fit per ISO metric standards, with dimensions including 5mm length, 7mm head diameter, and 4mm head height. It complies with ISO 4762 and DIN 912 specifications for socket head cap screws, and meets ASTM B117 for corrosion resistance testing. Additionally, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material sustainability.
