A socket includes a socket body having a periphery formed with a plurality of insertion recesses each having two opposite sides each formed with a first urging face and has a mediate portion formed with a second urging face located between the first urging faces of the two opposite sides, so that the socket body of the socket has a greater structural strength, thereby preventing the socket from being broken or worn out due to an excessive torque during operation of the socket.
