A wrench socket assembly comprises a socket having a main body; the main body including: an upper end portion being coated with silver thin film and having an inside formed with a mounting recess; the mounting recess of the main body of the socket having a wall formed with at least one positioning hole; the upper end portion of the main body having a peripheral wall formed with at least one through hole penetrating through the peripheral wall of the mounting recess; and a lower end portion having a color different from that of the upper end portion. A wrench with a pin can be used with the socket. The pin can be locked into the through hole or the positioning hole of the mounting recess so as to fix the socket to the wrench.
