## Abstract

The disclosure provides a pre-embedded anti-loosening nut embedded in a plastic component. The pre-embedded anti-loosening nut includes a main body portion and a plurality of radiating portions. The main body portion has a threaded hole. The radiating portions are disposed around a periphery of the main body portion. Each of the radiating portions has a first side and a second side connected with each other. The first side and the second side form a first included angle, and the second side is connected with the first side of another adjacent radiating portion to form a second included angle.

## Claims

### Claim 1

A pre-embedded anti-loosening nut embedded in a plastic component, comprising:
a main body portion having a threaded hole; and
a plurality of radiating portions disposed around a periphery of the main body portion, wherein each of the radiating portions has a first side and a second side connected with each other, the first side and the second side form a first included angle, and the second side is connected with the first side of another adjacent radiating portion to form a second included angle.

### Claim 2 (depends on 1)

The pre-embedded anti-loosening nut according to claim 1, wherein the second side of the radiating portion and the first side of the another adjacent radiating portion are neither parallel nor perpendicular to each other.

### Claim 3 (depends on 1)

The pre-embedded anti-loosening nut according to claim 1, wherein the first included angle is an acute angle, and the second included angle is an obtuse angle.

### Claim 4 (depends on 1)

The pre-embedded anti-loosening nut according to claim 1, wherein a height of each of the radiating portions is greater than or equal to a diameter of the threaded hole.

### Claim 5 (depends on 1)

The pre-embedded anti-loosening nut according to claim 1, wherein the radiating portions are disposed around the periphery of the main body portion at equal intervals.

### Claim 6 (depends on 1)

The pre-embedded anti-loosening nut according to claim 1, wherein along a thickness direction of the main body portion, the threaded hole has a first opening on a top surface of the main body portion, the threaded hole has a second opening on a bottom surface of the main body portion, and a center of the first opening is eccentric to a center of the second opening.
