Introducing the versatile and efficient flange nut, also known by various names like washer nut, serrated nut, and hexagonal flange nut. This innovative fastening solution features a wide flange at one end, effectively serving as an integrated washer. Dive into the comprehensive details of this essential component:
1. Structure and Design: Elegantly crafted mostly in a hexagonal shape, flange nuts are made from robust, hardened steel, usually enhanced with a galvanized finish. The thoughtfully designed flange significantly increases the contact area with the workpiece. This smart engineering ensures the even distribution of nut pressure across a broader surface, minimizing component damage and enhancing connection stability.
2. Materials and Specifications: A diverse array of materials, such as A3 low carbon steel, 35K high-speed steel wire, and 45 steel, cater to various hardness levels ranging from level 4 to level 12. Commonly found specifications include M5, M6, M8, M10, M12, and M16. Specifications exceeding M20 are rare and generally feature flat flanges, characterized by their toothless design.
3. Features and Uses: Distinctive for its anti-slip tooth pattern, the flange nut enhances friction, effectively preventing loosening. They are indispensable in demanding applications requiring exceptional tightness and stability, such as pipeline connections, securing metal plates, elevator manufacturing, and marine engineering. The serrated flange offers a reliable locking function, safeguarding against fastener loosening due to vibrations.
4. Advantages: Flange nuts shine in versatility, allowing for easy adjustment and disassembly post-installation, offering unmatched flexibility. By leveraging the remaining rotational resistance, they adeptly reduce preload force while maintaining a robust fastening effect.
In conclusion, flange nuts are pivotal in diverse applications demanding high tightening force and unwavering stability. Their unique design and exceptional performance make them indispensable in ensuring secure and reliable connections.
