If you have a ball with threading that is not adjusting correctly to a barbell, make sure that the ball and the barbell have opposite threads. One of them has to be externally threaded and the other one internally threaded.

Also, it is essential to make sure that both of them are of the same thread thickness. If you have a 1.2 mm (16G) barbell, then all of its balls should be 1.2 mm.

Please note that if you are buying spare parts from different manufacturers, our products may not fit in your existing jewelry. That is why it is best to buy all your jewelry and spare parts from the same source.

To better identify the source of the problem, please check also the barbell or ball on other replacement items. That way you would be able to figure out if the problem is due to a bad ball or a bar. If your barbell has two ends, please test both ends. Mix and match so you excluded every option.

If you have checked all of the above but the problem persists, please send a video to our support crew at help@bodymod.support

We need to be able to see what the problem is so that we can help you, so please attach an explicit video to your first contact.
