Core features of Round Coupling Nut / Connecting Nut
- Round body: No sharp edges, avoids scratchingand is easy to install in narrow or concealed spaces
- Full-through thread: Firmly connects two bolts for length extension or spacing adjustment, ensuring stable force transmission
- High coaxiality: Cylindrical structure guarantees alignment of connected bolts, reducing load deflection
- Smooth surface: Resists dirt accumulation, easy to clean and suitable for semi-visible assemblies
- Wide application: Ideal for machinery, pipelines, electrical equipment, and scenarios requiring bolt docking without protruding edges
