Abstract
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.
