Core features of Long Hex Coupling Nut
- Full-through thread: Connects two bolts to extend length or adjust spacing, achieving integral force transmission
- High coaxiality: Long body design ensures alignment of connected bolts, avoiding deflection under load
- Hexagonal profile: Fits standard wrenches, easy to tighten and position during assembly
- Strong rigidity: Extended body enhances structural stability, suitable for high-precision or heavy-load connections
- Wide application: Ideal for machinery, construction, pipelines, and scenarios requiring bolt length extension or docking
