Need a custom length 1/2 inch hex hub? Need to add custom features to your hub or make a large hex bore spool? Custom machine your own with our hex hub extrusion! In our current machining processes for making our 500EX Hex Hub (am-2568) remnants are left. We refuse to throw them out! We want you to be able to make custom hubs with them! Since these components have come out of a machine they may have some visual imperfections, sharp edges, chips and oil on them, please be cautious when receiving.
