Assembly Part, Method of Assembling an Assembly Part, and Fastening Insert

A method of assembling an assembling part, comprising:

• providing the assembly part including a body traversed by a traversing hole and a fastening insert configured to receive a fastening device in a hollow of the fastening insert along a first direction to fasten the assembly part to the counterpart, the fastening insert has a proximal end portion and a distal end portion in the first direction;
• positioning the fastening insert in the traversing hole;
• and
• plastically deforming a portion of the fastening insert to realize a form fit between the fastening insert and the body in the first direction and in a second direction opposite to the first direction.

A method of fastening an assembly part to a counterpart, comprising:

• assembling an assembly part including a body traversed by a traversing hole and a fastening insert configured to receive a fastening device in a hollow of the fastening insert along a first direction to fasten the assembly part to the counterpart, the fastening insert has a proximal end portion and a distal end portion in the first direction, the fastening insert is positioned in the traversing hole, a movement of the fastening insert in a second direction opposite to the first direction is blocked by a first form fit between the distal end portion and the body, a movement of the fastening insert in the first direction is blocked by a second form fit between the proximal end portion and the body;
• positioning the counterpart in contact with the assembly part, a through hole of the counterpart is centered on the traversing hole and faces one of the proximal end portion and the distal end portion of the fastening insert;
• and
• mating the fastening device through the through hole with the fastening insert of the assembly part.
