Professional Applications & Engineering Value
This M20 flange lock nut delivers critical vibration resistance in heavy machinery, automotive, and structural applications where dynamic loads threaten joint integrity. The zinc-plated steel construction provides essential corrosion protection while maintaining Class 8 strength for high-stress environments. The integrated serrated locking flange eliminates the need for separate washers and locking elements, simplifying assembly while creating permanent resistance to rotational loosening. Engineered to DIN 6923 and ISO 4161 standards, this metric coarse thread nut ensures compatibility with international components and reduces the risk of thread stripping during high-torque installation. The 42.8mm flange diameter distributes clamping force over a wider area, protecting softer materials and reducing surface deformation in critical connections.
Specification Summary & Compliance
This flange lock nut features M20x2.5 metric coarse threads with Class 6H thread fit tolerance for precise engagement. Manufactured according to DIN 6923 and ISO 4161 specifications with Class 8 strength rating. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives, ensuring safe use across industrial sectors. Dimensions include 30mm width, 20mm height, and 3mm flange thickness with right-hand thread direction and external hex drive configuration.
