4mm Bore, 12mm Hex Wheel Mount (Shaft)

These 12mm Hex Adaptors allow you to attach our wheels to drive shafts. Simply insert the shaft into the adaptor and tighten the set screws. For the 1/4" bore adaptor, we recommend using our d-shafting and aligning the set screw to the flat part of the shaft - this will give you a better hold. The 6mm bore adaptors work with our standard, precision and HD planetary gearmotors. The 4mm bore set is compatible with our precision planetary motors. Includes (1) complete set
