ABSTRACT:
An anvil for use in riveting one element to another element such as belting and a clasp for the belting. The anvil defines at least one aperture, and preferably a plurality thereof, for receiving detachable, rivet-carrying nails, whereby a rivet carried on the nail has an end that faces the anvil. The anvil defines an outer face surrounding the aperture for engaging and shaping the rivet end. The outer face is free of adjacent, upstanding walls beyond the normal diameter of the rivet and outside of and facing the aperture. Accordingly, the rivet end may spread freely outwardly from the aperture as the anvil shapes the rivet end, contrary to the prior art.
