I saw that QR code on the rod and thought it was interesting. It can indeed contain quite a lot of data. I actually suspect it is being used precisely to store more information than just a part number. A regular bar code would be fine for just a part number that thus making a QR going overboard. My speculation though it that it does not contain individualized dimensional information.
