An insert to be crimped on a support includes a body having a shank extending along a longitudinal axis and including a crimping section configured to deform into a crimping bead to crimp the insert on the support, and a flange presenting a surface facing the crimping section and extending along an axis perpendicular to the longitudinal axis, the flange having a constant thickness and presenting a fold forming a groove situated on the surface and designed to receive a seal. A fixing part includes the insert and a seal housed in the groove of the insert, and a fixing assembly includes the fixing part and a support on which the fixing part is crimped.

Insert to be crimped, fixing part and assembly comprising one such insert and methods for manufacturing such parts

A tapped insert to be insert molded comprises a shank provided at its axial ends with flanges delineating two axially opposite heads of the insert. The shank is provided with an internally threaded axial section to form a tapping. Means for blocking the insert in rotation after insert molding and means for blocking the insert axially in translation after insert molding are arranged on the outside of the shank. The shank comprises at least one fusible area of greater axial deformability located between the threaded axial section and one of the heads. The fusible area is configured to deform under a predefined axial compressive force applied to the heads without causing deformation of the threaded axial section. The invention also relates to a method for insert molding such an insert.
