Unveiling the Flange Nut, also known as the washer nut, serrated nut, or hexagonal flange nut. This essential component features a wide flange at one end, acting as an integrated washer. Discover the intricacies of the flange nut in our detailed breakdown:
1. Structure and Design: Typically hexagonal, flange nuts are crafted from hardened steel and often boast a sleek, galvanized finish. The ingenious flange design amplifies the contact area with the workpiece, effectively distributing the nut's pressure across a broader surface. This design innovation minimizes component damage while enhancing the connection's stability, a testament to its robust engineering.
2. Materials and Specifications: Flange nuts are crafted from a variety of materials, including A3 low carbon steel, 35K high-speed steel wire, and 45 steel, with hardness levels ranging from level 4 up to level 12. Commonly available specifications include M5, M6, M8, M10, M12, and M16, while specifications beyond M20 are rare and typically feature flat flanges, devoid of teeth, for specialized applications.
3. Features and Uses: The flange nut's anti-slip tooth pattern design enhances friction, effectively preventing loosening. It's a reliable choice for applications demanding high stability and tightness, such as pipeline connections, metal plate fastening, elevator manufacturing, and marine engineering. The serrated flange adds a locking function, safeguarding fasteners against vibration-induced loosening.
4. Advantages: Post-installation, flange nuts offer the convenience of adjustment and disassembly, making them exceptionally versatile. By harnessing remaining rotational resistance, they reduce preload force, ensuring a steadfast fastening effect that endures over time.
In essence, flange nuts are indispensable in scenarios necessitating high tightening force and unwavering stability. Their unique design and exceptional performance make them a cornerstone in diverse industrial applications.
