In this guide, we walk you through how to pick compatible jewelry ends for your body jewelry shafts and anchors.

Jewelry Threading

Threaded jewelry consists of two to three pieces--a shaft or anchorOpens a new window and one or two decorative endsOpens a new window. For instance, a labret stud consists of a shaft with a fixed back and a removable end, whereas a bent barbell has two removable ends. All threaded jewelry has one of two types of threading used to connect the component parts: external threading or internal threading. Internal threading means that the barbell shaft or anchor has recessed threads drilled into it; the matching internally-threaded endsOpens a new window have compatible posts sticking out of them that screw into the barbell shaft or anchor's internal threads. External threading means that the jewelry shaft or anchor has threaded ends sticking out of it; the matching externally-threaded endsOpens a new window have recessed threads drilled into them so they can be screwed onto the coordinating barbell shaft or anchor's external threads.Opens a new window Sometimes shafts and anchors of varying gauges will all share the same size threading so that a standard size end, like a 14g dermal topOpens a new window, can be used with shafts and anchors in a few different gauges. When you're puchasing body jewelry partsOpens a new window that you want to pair together or replacement ends for a piece of jewelry you bought previously, it's important to pay close attention to the thread sizes of the pieces you're buying.
