The flange nut, often referred to as a washer nut, serrated nut, or hexagonal flange nut, is a remarkable component featuring a broad flange at one end. This design enables it to function as an integrated washer. Below is an in-depth exploration of the impressive flange nut:
1. Structure and Design: Predominantly hexagonal, flange nuts are crafted from robust, hardened steel and typically boast a galvanized finish. The innovative flange design significantly amplifies the contact area with the workpiece, ensuring an even pressure distribution across a wider surface. This smart engineering minimizes potential component damage while enhancing the connection stability.
2. Materials and Specifications: Flange nuts are manufactured from a variety of materials, including A3 low carbon steel, 35K high-speed steel wire, and 45 steel, offering a hardness spectrum from levels 4 to 12. They are available in common specifications such as M5, M6, M8, M10, M12, M16, with larger sizes like M20 being rarer and typically featuring flat flanges devoid of teeth.
3. Features and Uses: The flange nut's anti-slip tooth pattern is ingeniously designed to boost friction, ensuring the nut remains secure and resists loosening. Ideal for demanding applications that necessitate exceptional tightness and stability, they are prevalent in pipeline connections, metal plate fixtures, elevator manufacturing, and marine engineering. The serrated flange further enhances its locking ability, safeguarding fasteners from vibration-induced loosening.
4. Advantages: Post-installation, flange nuts allow for convenient adjustment and disassembly, providing unmatched flexibility. They efficiently reduce preload force by leveraging residual rotational resistance, guaranteeing a superior and enduring fastening experience.
In essence, the flange nut stands as a crucial player across diverse scenarios demanding robust tightening and steadfast stability. Its distinctive design and exceptional performance make it indispensable.
