Abstract
A tubular sleeve clamps the work during a drilling step, following which a tubular anvil moves within the sleeve to support the work while a rivet is thrust into the work with an interference fit. The tubular anvil is then withdrawn and moved with an anvil pin to form an upset head. If desired, the pin can then be retracted, and the outer portion of the upset head partially sheared by the tubular anvil and flattened against the work.
