The mechanism used to secure the decorative end to the post, known as threading, has significant implications for safety and comfort in a piercing. The term “internally threaded” refers to a specific, high-quality construction standard that professional piercers prefer. Understanding this design is fundamental to ensuring the best possible experience, especially for new or healing piercings.
The Structure of Internally Threaded Jewelry
Internally threaded jewelry is designed so that the threads are contained completely within the hollow shaft of the barbell or post. The post itself has a smooth, polished exterior and a recessed opening that acts as the female component of the connection. The decorative end, such as a ball or gem, features a small, smooth-tipped protrusion with external threading, serving as the male component.
To secure the jewelry, this threaded pin is screwed into the receiving hole inside the post. When fully assembled, the threads are entirely enclosed within the metal. The smooth, thread-free surface of the jewelry post is the only part that ever contacts the delicate tissue of the piercing channel. This design is more complex to manufacture, which often correlates with the use of higher-quality, biocompatible materials like implant-grade titanium.
Why Threading Type Matters for Piercing Health
The choice of threading directly impacts the health of the fistula, the channel of skin that forms inside a piercing. Externally threaded jewelry places the threads on the outside of the post, meaning these sharp, microscopic ridges must pass through the piercing channel upon insertion and removal. This exposed threading can cause abrasive damage to the delicate skin lining the piercing.
This scraping action can result in micro-tears and irritation, increasing the risk of inflammation, prolonged healing times, and the formation of piercing bumps. The exposed threads also create minute crevices that can harbor bacteria, dead skin cells, and debris, which are pushed into the healing tissue. Internally threaded jewelry eliminates this concern by ensuring only the smooth, polished surface of the post moves through the piercing, reducing physical trauma.
Smoother Insertion and Long-Term Wear
The smooth transition offered by internally threaded jewelry is the industry standard for initial piercings. By avoiding the scraping and micro-trauma associated with external threading, the jewelry minimizes the body’s inflammatory response. Reduced inflammation translates to less swelling, less pain, and a decreased likelihood of rejection.
The enclosed connection also contributes to better long-term hygiene and security. Because the threads are hidden, there is less opportunity for microscopic particles to accumulate in the connection point, which keeps the jewelry cleaner and reduces the risk of localized infection. Furthermore, the precise machining required for internal threading typically results in a more secure connection between the post and the end piece. This security means the decorative end is less likely to loosen and fall off accidentally.
