Converter Post for Changing 16g External Ends Into Ends for 12g or 14g Internally-Threaded Jewelry

If you have a 16g externally-threaded jewelry top you love, but you want to be able to use it with 12g or 14g internally-threaded body jewelry that has an internal 1.2mm thread pattern, all you need is this little converter post. Screw it into any 16g externally-threaded end, and then you can use the end with a 12g or 14g internally-threaded shaft, dermal anchor, surface barbell, or other piece of internally-threaded body jewelry with matching internal 1.2mm threading.

This converter post will also allow you to connect 2 12g or 14g internally-threaded pieces of jewelry together, as long as both pieces have the same thread pattern. Use this converter post to create a longer straight barbell, to add a straight shaft to a labret post so you can use it as cheek piercing jewelry, and more. The options are endless! With tools like this, you can make your wildest body jewelry ideas come to life!
