China Hexagonal flange face bearing toothed nut Manufacturer, Supplier, Factory

Engineers and industrial professionals seeking superior locking solutions will find our Hexagonal flange bearing toothed nut to be an exceptional choice for high-vibration applications. This component is part of our comprehensive range of Hexagon nuts with flange, designed to provide a secure and reliable fastening point. Unlike standard nuts, our Hexagon flange nuts integrate a wide bearing surface and a toothed locking mechanism, which effectively distributes clamp load and prevents loosening under dynamic stresses. For applications demanding maximum security, our premium Hexagonal Flange Bearing Nut offers unparalleled performance and durability, making it a trusted component in automotive, machinery, and heavy equipment assembly.


The Hexagonal flange face bearing toothed nut is engineered with precision to meet rigorous industrial standards. Its integrated flange eliminates the need for a separate washer, simplifying assembly and reducing component count. The teeth on the bearing face bite into the mating surface, creating a powerful locking action that resists rotation caused by vibration and thermal cycling. Manufactured from high-grade materials, this nut ensures consistent performance and a long service life even in the most demanding environments.
