Hexagon nuts are six-sided nuts commonly used in mechanical and industrial applications for fastening purposes. They are designed to be compatible with bolts and threaded rods of corresponding sizes, providing a secure and tight connection when tightened properly.

These nuts are typically made of metal, such as steel, stainless steel, brass, or aluminum, although they can also be found in plastic or other materials depending on the specific application requirements.

The six flat sides of a hexagon nut provide easy gripping surfaces for tightening or loosening with a wrench or a socket wrench. This design allows for efficient installation and removal, making hexagon nuts a popular choice in various industries including automotive, construction, manufacturing, and aerospace.

Hexagon nuts come in a variety of sizes and thread types to accommodate different bolt diameters and pitches. They are available in standard metric sizes as well as imperial (inch) sizes, ensuring compatibility with a wide range of fasteners.

In addition to standard hexagon nuts, there are also variations such as nylon-insert lock nuts, which feature a nylon collar inside the nut to provide resistance against loosening due to vibration or torque. Other variations include flange nuts, which have an integrated flange that distributes pressure and prevents damage to the surface being fastened, and serrated flange nuts, which have serrations under the flange to grip the surface and prevent loosening.

Overall, hexagon nuts are essential components in mechanical assemblies, offering a reliable and versatile solution for securing bolts and threaded components in place.
