## Optional Hex Couplings (Bore Sizes: 3mm, 4mm, 5mm, 6mm, 8mm)
We strongly recommend using our **industrial-grade clamping hex couplings** over traditional set-screw types. Clamping couplings provide long-term, stable fixation under heavy vibrations, ensuring your wheels never loosen or fall off during operation.
* **Clamping Hex Coupling**: High-strength aluminum alloy[span_19] , across flats 12mm , available bore diameters: 3mm, 4mm, 5mm, 6mm, 8mm.
* **Set-Screw Hex Coupling**: Iron material, across flats 12mm, available bore diameters: 3mm, 4mm, 5mm, 6mm *(Note: 8mm is not recommended for set-screw types due to high driving loads).*

## Important Notes
1. Due to machining tolerances, the actual tire diameter may have a 2mm variance.
2. The 85mm solid heavy-duty natural rubber tire shares the exact outer dimensions as the standard version, differing only in color (Black vs. Dark Grey) and internal structure.
