The second limiting portion 123 is disposed at one end of the stud body 121 facing the nut body 111. Moreover, the second limiting portion 123 is connected to the side surface of the stud body 121. In actual application, the second limiting portion 123 can be embedded into and cut the surface of the site during the process of screwing the stud body 121 into a preset fastening site, thereby further improving the connection stability between the stud portion 120 and the fastening site. Specifically, the second limiting portion 123 includes a plurality of second limiting bosses c. The plurality of second limiting bosses c are disposed along the side surface of the stud body 121 on its outer periphery. Moreover, each second limiting boss c is connected to the end face of the nut body 111. Thus, when the stud body 121 is screwed into a preset fastening site, the plurality of second limiting bosses c can rotate and cut the surface of the fastening site, and then be embedded into the fastening site, thereby cooperating with the plurality of first limiting bosses b to strengthen the fastening performance of the stud body 121.

[0033] Please refer to Figures 1 to 4, Further, each second limiting boss c is provided with a cutting edge c1, and the cutting edge c1 is arranged on the side of the corresponding second limiting boss c facing the screwing-in direction of the stud body 121. When the stud body 121 is screwed into a preset fastening position, the cutting edge c1 can effectively improve the cutting ability of several second limiting bosses c on the surface of the fastening position, which is more conducive to several limiting bosses being embedded into the interior of the fastening position.

[0034] Please refer to Figures 1 to 4 , Further, the nut portion 110 is provided with a threaded hole 113. The threaded hole 113 is arranged inside the nut portion 110.

[0035] Please refer to Figures 1 to 4 , Further, the stud portion 120 is provided with an external thread 124. The external thread 124 is arranged on the outer surface of the stud portion 120. And the external thread 124 extends a preset distance towards the nut portion 110 from one end of the stud portion 120 facing away from the nut portion 110 along the length extension direction of the stud portion 120, so as to form an external thread 124 with a preset length.

[0036] In summary, the carbon steel male-female stud disclosed by the present utility model wraps a non-slip layer on the outer side of the nut body, thereby effectively improving the anti-slip performance of the side surface of the nut portion. In practical applications, the non-slip layer increases the clamping stability of the clamping device on the nut portion by increasing the contact area on the side surface of the nut portion. The non-slip layer is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are respectively arranged on the side surface of the anti-slip groove. The plurality of anti-slip grooves can effectively increase the contact area on the surface of the non-slip layer, thereby adding a plurality of clamping positions for the clamping end of the external clamping device and effectively increasing the contact area between the non-slip layer and the clamping device, so as to effectively improve the anti-slip performance on the surface of the non-slip layer. At the same time, it can also reduce the raw material loss during the forming process of the non-slip layer, thereby saving production costs. In addition, the non-slip layer can be made of a flexible non-slip material, so that the non-slip layer has a preset deformation ability.
