These are Threaded Surgical Steel Spikes and Cones that will fit 14 Gauge Only.
As with all of our Replacement Balls, due to different companies threading, we do not guarantee that they will fit the piece that you are ordering it for, even if it was originally purchased from us.
Threaded pieces are for use with any type of barbell where the end piece screws on. These have the threaded hole in, and thus can only be used on the standard externally threaded barbells.
