[0002] A nut is a part that is screwed together with a bolt or a screw to fasten. It is a component that all manufacturing machinery must use. According to the different materials, it is divided into several types, such as carbon steel, stainless steel, and non-ferrous metals (such as copper).

[0003] Nuts are parts that tightly connect mechanical equipment. Through the inner threads, nuts and bolts of the same specifications can be connected together. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts.

[0004] After the main body of the nut is processed, it is necessary to drill a hole in the middle of the nut using a drilling device, and then a subsequent tapping device taps the inside of the hole in the middle of the nut.

[0006] However, after the drilling equipment drills the nut, some debris will remain inside the hole. The debris adheres to the inner wall of the hole and moves with the nut, causing the debris to slide on the inner wall of the nut, easily causing scratches on the inner wall of the nut hole and easily affecting the accuracy of subsequent tapping of the nut.

[0007] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content
