The invention relates to a fastener. The fastener is used for mounting a first part to a second part. The fastener comprises a stud and a buckling ring, wherein at least one barb part is arranged on the stud and is configured to enable the stud to be conveniently inserted into the first part and to prevent the stud from being drawn out of the first part along the direction opposite to the insertion direction; the buckling ring sleeves the stud and is configured in a manner that the buckling ring is conveniently inserted into the second part, the insertion distance is limited, and the buckling ring is prevented from being drawn out of the second part along the direction opposite to the insertion direction and is remained in the second part. According to the fastener, a thermal-insulation and sound-insulation layer of an airplane can be firmly mounted, the dismounting is convenient, and the requirements on the fire resistance and the corrosion resistance of the thermal-insulation and sound-insulation layer are met. The invention further discloses a method for mounting the thermal-insulation and sound-insulation layer by virtue of the fastener.
