A method is provided for installing a fastener into an opening of a structure. The fastener includes a sleeve and a pin threadably received into the sleeve. The method includes inserting the fastener into the opening, grabbing a pintail of the pin, and deforming a tail of the sleeve radially outward relative to a centerline axis of the fastener by automatically displacing the pin longitudinally along the centerline axis relative to the sleeve. The method also includes rotationally shearing the pintail of the pin from a shaft of the pin.

A rivet for blind fastening may include a screw with a handling element, a break groove, a head separated from the handling element by the break groove, and a threaded part. The rivet may also include a sleeve with a collar and a tubular shank having an internal thread intended to come into engagement with the threaded part of the screw. The handling element includes a first handling portion able to guide introduction of the rivet in a setting tool, and a second handling portion able to transmit a torque, the two handling portions being separated by a blocking portion able to limit an axial movement of the rivet in a setting tool. A setting nose may be used for installing such a rivet, and the rivet, setting nose and a setting method can be used in the assembly of aircraft structures.
