High-quality materials, excellent craftsmanship, safe, reliable and durable, Many size and complete specifications, convenient and flexible installation, convenient maintenance and better cost performance.

The hexagonal coupling can be adapted to our hexagonal wheels, so choose a hexagonal coupling with a bore of how many millimetres for how many diameters of shaft you need!

Note:
- The hexagonal coupling is used to connect the motor shaft and the hexagonal wheel, and cannot be used to connect two shafts.
- The hexagonal coupling side fastening with screws M4, hexagonal surface of the central hole of the set screw is M4 screws.
- One allen key for every order and Two grub screws (M4) for every coupling.
