China Hexagonal collar nut Manufacturer, Supplier, Factory

Hexagonal collar nuts, also known as hexagon nuts or hex nuts, are essential fasteners widely used across various industries. These specialized Hexagon collar nuts are designed with an integrated washer-like flange that distributes load more effectively, reducing the risk of surface damage and providing a larger bearing surface. This design is particularly beneficial in applications where vibration resistance and improved clamping force are critical. The six-sided hex shape allows for easy installation and removal with standard tools like wrenches and sockets. Available in various materials, sizes, and finishes, these nuts are ideal for automotive, construction, and machinery assemblies, ensuring reliable performance and longevity.


The Hexagonal collar nut is engineered to meet stringent industry standards, offering superior performance in demanding environments. Its unique collar acts as a built-in washer, eliminating the need for a separate component and streamlining the assembly process. This design enhances vibration resistance, preventing loosening under dynamic loads. Manufactured from high-quality materials, the Hexagonal collar nut provides excellent corrosion resistance and durability. Below are the detailed specifications presented in a list and table format for clarity and precision.
