Abstract: The invention relates to a tool (15) for installing fasteners, said tool comprising: a sheath containing a cylindrical housing (18) with a polygonal base, a roller cage (19) accommodated within said cylindrical housing, said cage comprising: a cylindrical support (33) with a substantially circular base, capable of pivoting within the cylindrical housing. rollers (34) disposed on the perimeter of the support, each roller being able to rotate with respect to said support, a compressing spring (36) exerting a radial force on the rollers in the direction of the main axis, the tool further comprising a restoring member (37) tending to bring the rollers of the cage to face the edges (27) of the cylindrical housing of the sheath.

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.
