Nailhead – also meant to substitute for Rhinestones, a nailhead is a metal object like a Rhinestud, but with a flat, rounded top like the head of a nail. For example, a Red Rhinestud will actually be red, as opposed to a Rhinestone where the color depends on glass, light, etc. These are valued in apparel decorating because they are always lead free, are less expensive than Rhinestones and come in a more defined color palette. Normally, a Rhinestud will be “Hotfix”, just like most Rhinestones in apparel decorating and have an angular head. Rhinestud – these are metallic copies of rhinestones. Heat is applied, through an iron or heat press, in order to “fix” the stones onto a textile like a t-shirt. Hotfix or Hot Fix – stones, studs or other objects that are coated with a heat activated glue on one side.
The word Rhinestone was coined because the original product was made from rock crystals found on the banks of the Rhine River. Rhinestone – according to Wikipedia, a rhinestone is a simulated gem made from crystal, glass or acrylic.
