A large part of our interest with threadless jewelry is the innate safety feature it offers. If your jewelry gets caught on anything the connection should separate before skin breaks. Externally threaded jewelry also doesn’t smoothly pass through the piercing. When the jewelry is removed, the threads can cause trauma to the skin and let bacteria grow in the micro tears. ASTM-F136 grade titanium body jewelry is of the highest quality, and has fewer impurities than other types of titanium. F-136 refers to the specific grade of titanium, one that was designed for medical implants because of its high standards for biocompatibility .
Ill-fitting jewelry increases the likelihood of swelling, embedding, and other complications if too small, or catching and excessive trauma, if too large. Hold both ends of the jewelry, and pull them in opposite directions. And don’t do it over your bathroom sink without a plug — these pieces are very small, and you don’t want to lose your precious jewelry down the drain.
As you’ll read below, the two types of threaded body jewelry—internal and external—are vastly different. Also known as a navel curve or curve, so named because of their curvature. A curved barbell is mechanically identical to a straight barbell, except for being curved. Curvature on a curved barbell can range from almost straight to circular, with some barbells actually jewelry photography props being spiral, with the ends overlapping but separated to allow the insertion of the jewelry. A variation on this design is a J-bar, a slightly curved barbell with a 90 degree bend near one end, used in vertical navel piercings to position the decorative end of the jewelry more appropriately. They can be either internally threaded or externally threaded.
In contemporary society, barbell-style jewelry was popularized by Jim Ward, founder of Gauntlet , in the 1970s. He was introduced to barbell-style jewelry by Horst Streckenbach “Tattoo Samy” (1926–2001), a tattooist and piercer from Frankfurt, Germany, and his student Manfred “Piker” Kohrs from Hanover, Germany. Threadless jewelry, sometimes called push-fit or press-fit jewelry, was invented by NeoMetal in 1997. It doesn’t have any threaded pieces; instead, the jewelry is held together by tension. Threadless body jewelry contains two pieces, the decorative end, which can also feature a gem or cabochon, and the labret post or barbell.
All threaded or press-fit jewellery must have internal tapping . Another common benefit is that internally threaded jewellery is often countersunk, meaning that the ball, gem or end makes a much closer and tighter connection with the bar. When it comes to professional body jewelry there are definitely DO’s and DON’T’s! At Nathan’s, we only utilize professional, implant grade body jewelry for your piercings. Meaning we only use internally threaded jewelry versus externally threaded jewelry .
