12mm Hex Shaft Wheel Adaptor (Set) 0.250" Bore
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. We recommend aligning the set screw to the flat part of the shaft - this will give you a better hold. These adaptors require a 3/32 hex key (sold separately).
