Traditionally an internally threaded body jewelry is more expensive to purchase than externally threaded body jewelry.
What does internally threaded mean?
Internally threaded means that the inside of the part of the jewelry, that will pass through your body is smooth. The threading or 鈥榮crew鈥?is on the removable end, such as a ball end on a barbell. This end will screw into the hole that has been drilled with the matching pattern, so it will receive the end of the jewelry and create a snug fit.
