Flange nuts are a type of fastener designed with an integrated flange at one end, which distributes the load over a larger surface area, reducing the need for a separate washer. These nuts are often hexagonal in shape, similar to hex nuts, making them easy to grip with standard tools. Flange nuts come in various types, including serrated flange nuts, which have serrations on the flange to prevent loosening due to vibration. For added corrosion resistance and durability, many flange nuts are zinc plated, offering a protective layer that enhances their performance in harsh environments. These features make flange nuts a reliable choice for securing components in automotive, construction, and industrial applications.
