Professional Applications & Engineering Value
Engineered for demanding industrial settings, these M6 flat head screws in black-oxide alloy steel address critical challenges like vibration loosening and environmental degradation. The Class 10.9 strength grade and coarse 1 mm pitch threading provide robust fastening in machinery, automotive assemblies, and structural frameworks, where high tensile loads and repetitive stress are common. The fully threaded design with a 90° countersink angle ensures even load distribution and a seamless fit, reducing the risk of material fatigue. Ideal for applications requiring precision metric screws with compliance to DIN 7991/ISO 10642, they offer long-term reliability in corrosive or high-temperature environments, supported by the durable hex drive for efficient maintenance.
Specification Summary & Compliance
This screw features M6 x 1 mm coarse threads with a Class 6g thread fit for precise tolerance, adhering to DIN 7991 and ISO 10642 standards. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity. The 18 mm length and fully threaded configuration meet rigorous industrial specifications for consistent performance.
