I have no idea what these were used for. I got them at a closed down manufacturing facility in rural Ohio. I think they made some sort of metal items. These may have been part of the drilling process. They have a pretty thick wall to them, (about 1/8") not just some type if thin sheet metal
Each one weighs a little over 1 ounce. They have some sort of set screw that you can remove.
Use your imagination.
