A universal socket includes a first socket, a second socket, and a rivet. The first socket has a fitting hole defined in one end and a receiving recess defined in the other end thereof. A through hole is diametrically defined in the first socket and communicating with the receiving recess. A second socket has a ball member formed thereon and disposed in the receiving recess. A slot is diametrically defined in and extends through the ball member. The slot communicates with the through hole when the ball member is received in the receiving recess. A rivet has a head and a forming head, wherein the rivet extends through the through hole and the slot to retain the ball member disposed in the receiving recess and preventing the second socket from disengaging from the first socket.
