Long Hexagonal Coupling Nut

Long hexagonal coupling nuts are typically used to connect two sections of externally threaded rod (e.g., double-ended bolts, threaded rods, etc.) or to extend the length of a threaded connection. Long hexagonal coupling nuts with unique geometric design and performance advantages, this product is widely used in high load, complex working conditions and long distance connection scenarios.

Core Performance Advantages

High load carrying capacity: Long hexagonal coupling nuts the elongated design makes the load evenly distributed, suitable for bridge expansion joints, steel structure frames and other heavy load connection scenarios.

Anti-vibration loosening: Long thread engagement can effectively absorb vibration energy and reduce the risk of loosening, suitable for mechanical equipment, rail transportation and other dynamic load environment.

Compatibility and Flexibility: Adapt to a variety of specifications of external threaded parts, simplify the design of complex assembly structure, save installation space and time costs.

Details

Long hexagonal coupling nuts have full-length internal precision threads that provide longer engagement lengths, significantly increase thread contact area, and enhance tensile strength and shear resistance.

Long hexagonal coupling nuts are typically designed with the same size threads on both ends to ensure a seamless fit with the connecting member for bi-directional threaded extensions or fixings. The nuts are of standard hexagonal construction for ease of installation with universal wrenches or automated tools, and have enhanced torsional resistance to prevent slippage during installation.

Application

Heavy machinery: Long hexagonal coupling nuts are used for the connection and extension of long-distance threaded components such as hydraulic cylinders and drive shafts.

Construction and bridge engineering: Reliable docking of multi-stage structures in embedded bolt systems.

Energy equipment: Used in wind power tower, transmission and transformation bracket and other key nodes that need to resist fatigue and wind vibration.

Customized assembly: Non-standard length and material connection solutions for special equipment (e.g. aerospace, shipbuilding).
