Abstract
A blind rivet element has a head portion and a shank adjacent to the head portion in an axial direction. The shank has an internal thread or a connecting portion for a threaded bolt and a deformation portion between the internal thread or the connecting portion for the threaded bolt and the head portion for forming a closing head when the deformation portion is deformed. The head portion has a radially outer region formed spaced apart from the shank in a radial direction. The head portion has at least one first protrusion protruding in the axial direction formed exclusively in the radially outer region of the head portion, and/or the head portion has at least one second protrusion protruding counter to the axial direction formed exclusively in the radially outer region of the head portion.
Claims18
A blind rivet element having a head portion and a shank adjacent to the head portion in an axial direction, wherein the shank has an internal thread or a connecting portion for a threaded bolt, and a deformation portion between the internal thread or the connecting portion for the threaded bolt and the head portion for forming a closing head when the deformation portion is deformed, wherein the head portion has a radially outer region formed spaced apart from the shank in a radial direction, wherein the head portion has at least one first protrusion formed exclusively in the radially outer region of the head portion, and wherein the head portion has at least one second protrusion formed exclusively in the radially outer region of the head portion, wherein the blind rivet element has a plurality of first protrusions protruding in an axial direction from a first side of the head portion and a plurality of second protrusions protruding counter to the axial direction from a second side of the head portion opposite the first side, wherein the plurality of first protrusions and the plurality of second protrusions are formed on a respective side of the head portion in an encircling direction about an axis formed in the axial direction, and wherein the plurality of first protrusions and the plurality of second protrusions are formed in an alternating manner and separated by a recess on the respective side of the head portion in the encircling direction.
A blind rivet element having a head portion and a shank adjacent to the head portion in an axial direction and extending in a shank-extending direction, wherein the shank has an internal thread or a connecting portion for a threaded bolt, and a deformation portion between the internal thread or the connecting portion for the threaded bolt and the head portion for forming a closing head when the deformation portion is deformed, wherein the head portion has a radially outer region formed spaced apart from the shank in a radial direction, wherein the head portion has at least one first protrusion formed exclusively in the radially outer region of the head portion, and wherein the head portion has at least one second protrusion formed exclusively in the radially outer region of the head portion, wherein the blind rivet element has a plurality of first protrusions protruding in a first direction that is parallel to the shank-extending direction and from a first side of the head portion and a plurality of second protrusions protruding in a second direction that is parallel to the shank-extending direction opposite the first direction and from a second side of the head portion opposite the first side, wherein the plurality of first protrusions and the plurality of second protrusions are formed on a respective side of the head portion in an encircling direction about an axis formed in the axial direction, and wherein the plurality of first protrusions and the plurality of second protrusions are formed in an alternating manner and separated by a recess on the respective side of the head portion in the encircling direction.
