Types of barbells


Internally threaded barbells

Named because the bar has smooth ends with receiving threads tapped into the end of the bar. In internally threaded jewelry, the bead has a receiving tube machined into it (this is referred to as "countersunk"), with a threaded post extending from the center, which mates with the threaded receiving tube on the bar. Being much less likely to cause damage and irritation, especially at the time of piercing, internally threaded jewelry is considered superior to externally threaded jewelry. It is usually slightly more expensive than externally threaded jewelry, due to the extra machining and labor involved.


Externally threaded barbells

So named because the shaft of the bar has threads at both ends to allow beads with receiving threads to be attached. Due to the potential damage or irritation to the piercing as the threads are passed through when the jewelry is inserted or removed as well as the popularity of the internally threaded barbell, the externally threaded option has become less common. This type of barbell is usually only used in cheap, mass-produced body jewelry. Some manufacturers make externally threaded barbells with "step-down threading", where the threaded section has a smaller diameter than the wearable section; these are fairly uncommon and usually internally threaded barbells are used in their place. Step-down threaded jewelry ends can be inserted into the blunt end of a hollow piercing needle, allowing for less irritation during initial placement than regular external barbells.


Curved barbells

Also known as a ''navel curve'' or ''curve'', so named because of their

Surface bars

s. A surface bar is a barbell where the bar has a pair of 90 degree bends, in the same direction (similar to a staple), to allow the jewelry to be used for surface piercings. This design minimizes the pressure that would be caused by other jewelry designs that contribute to rejection in healing surface piercings. Surface bars are produced with many different lengths between the two points.


Types of beads

Beads for barbells can vary widely in design and appearance, although the vast majority of beads are simply

, and his student Manfred "Piker" Kohrs from Hanover, Germany. "The first barbells I recall came from Germany. Doug had made contact with Tattoo Samy, a tattooist and piercer from Frankfurt. Over the years Samy came to the States a number of times and frequently showed up in LA to visit Doug. On one of his first visits he showed us the barbell studs that he used in some piercings. They were internally threaded, a feature that made so much sense that I immediately set out to recreate them for my own customers." Jim Ward and his magazine '' PFIQ'' have been crucial in the development of modern body piercing. They are worn in the cartilage of the ear but they are also worn on the lobe. The lobe is very popular because it can be performed in some countries without parental consent and it is more painless and easy to DIY.
