1. A fastener comprising:
a collar having a swaging surface made of a substrate material having a substrate colour; and
an indicator material having an indicator colour coated on at least part of the substrate material of the swaging surface, the indicator colour being visually different from the substrate colour,
wherein the coated collar is adapted to be swaged to move the collar from the unswaged condition to a swaged condition,
wherein the indicator material is adapted so that, in a correctly swaged condition when the swaging process has been correctly carried out, the indicator material is substantially removed to expose the substrate colour and thereby provide a visual indication that the swaging process has been correctly carried out.
