Professional Applications & Engineering Value
This M8 flange lock nut delivers critical vibration resistance in demanding applications where safety and reliability are paramount. The serrated locking design creates permanent friction against mating surfaces, effectively preventing rotational loosening caused by machinery vibration, impact loads, or thermal cycling. Manufactured from Class 10 steel, this metric lock nut maintains clamping force in high-stress assemblies while the integrated flange eliminates the need for separate washers, reducing component count and installation time. The coarse thread with 1.25mm pitch ensures rapid assembly in automotive, construction, and heavy equipment applications where vibration resistance and structural integrity cannot be compromised.
Specification Summary & Compliance
This flange lock nut conforms to DIN 6923 standard specifications with M8 coarse thread (1.25mm pitch) and Class 6H thread fit for precision engagement. The external hex drive (13mm width) and right-hand thread direction follow industrial conventions. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives, ensuring safe use across various industrial sectors. The 17.9mm flange diameter and 8mm height provide optimal dimensional characteristics for standard applications requiring reliable fastening solutions.
