The invention discloses an internal threaded pin which comprises a pin body (3). The internal threaded pin is provided with a through hole (32) which extends along the axial direction and penetrates through the pin body (3), and the partial inner wall, close to the exterior of a pin hole (4), of the through hole (32) is provided with an internal thread; and when the internal threaded pin is installed, gas in the pin hole (4) is discharged from the through hole (32), and the phenomenon that the gas in the pin hole (4) is compressed by the pin body (3) so as to generate resistance for installing the internal threaded pin can be avoided, therefore, the labor intensity for installing the internal threaded pin is further reduced; and the two ends of the internal threaded pin are provided with chamfers (33).
