Professional Applications & Engineering Value
Engineered for demanding industrial settings, these M6 hex head screws in black-phosphate steel address common challenges like corrosion and mechanical fatigue. The Class 10.9 strength grade and Rockwell C32 hardness ensure they withstand high tensile and dynamic loads, making them ideal for heavy machinery, automotive assemblies, and structural frameworks. The partially threaded design with coarse metric thread provides superior grip in materials prone to vibration loosening, while the flanged head distributes pressure evenly, reducing the risk of surface indentation. Compliant with DIN 6921 and ISO 898-1, these screws deliver consistent performance and reliability in critical industrial fastening applications, from manufacturing plants to construction projects.
Specification Summary & Compliance
This screw features precise M6 x 1 mm coarse thread with Class 6g tolerance for accurate fit, a length of 25 mm, and partial threading. It meets ISO 898-1 and DIN 6921 manufacturing standards, ensuring dimensional consistency and mechanical properties. Additionally, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and restricted substance adherence.
