Thread Patterns
As a rule the 14G internally threaded jewelry on our site is standard size which takes an internal thread pattern of 1.2mm and the 16G takes 0.9mm internal thread pattern.
Please be aware that 18G jewelry is not a standardized thread. Some manufactures make it 0.8mm thread pattern so test your thread on your 18G by trying to successfully thread a 16G top which is standard 0.9mm thread pattern and if it fits then you know your 18G piece also has 0.9mm thread pattern and any 16G internal top will also fit. It has recently become far more common for factories to make 18G thread pattern the same as 16G fitting a 0.9mm thread pattern and individual tops in 0.8mm are not commonly made anymore to be sold separately as a result.
Also the extended threading in our piercers special labrets are not standardized threading regardless of gauge - and only fit the post it comes with.
Threadless Jewelry - How it works
When you purchase threadless jewelry it may or may not come pre-bent. Usually if it is sold as a 2 pc combo there is already a bend in the pin top, however, it still needs to be checked to ensure it is a tight enough fit.
When you buy a separate top and base you almost surely will have to pre-bend your top pin.
Either way here is a helpful video that explains how but be warned you must be gentle and always apply pressure from the middle of the top not an end particularly if it is a long design. You must be gentle it is easy to break them if you bend repeatedly or too aggressively and this is not returnable for this reason.
