Abstract
An anvil for a blind riveting tool comprises an annular disc 23 of resilient nylon-6 material received in a counterbore in the front of a rigid backing or mount 25. When the tool is used to place a blind rivet, the nylon disc contacts the rivet shell head to support it against the pull of the mandrel. The disc is flexible enough to conform to the shape of the rivet head, thus maximizing the contact area and minimizing the contact thrust, and is soft enough not to damage or mark the rivet head surface, which may, for example, be painted.
