Quotes from Piercing FAQ
Septum Retainer: U-shaped piece of metal, either rounded or squared-off, and usually between 5/16» and 3/8» wide and 3/8» long. The spread of the shanks should be adjusted to fit the wearer so that the retainer may be comfortably flipped up into the nose. To prevent losing the retainer the shanks should be at least 5/16» long and adjusted so that the retainer is snug when flipped up and down.Wire in gauges larger than 10 is more difficult to shape into small dimensions. A few companies make large gauge retainers with thinner shanks so that the retainer can be shaped accurately. Solid plugs or eyelets may be more comfortable or more readily available than retainers for piercings larger than 8ga.
Septum Spike: A solid length of tapered metal, usually between 1» and 4» long. Styles available include straight, curved, or horse-shoe shaped. Some designs feature a notched center, which rests in the piercing.
Septum Tusk: Similar in appearance to the Septum Spike. The tusk comprises two pieces which screw together with a thinner center bar worn through the piercing. Thus someone with a 14ga piercing can appear to have a 4 ga piercing.
