Abstract

A socket assembly includes an outer socket, an inner socket mounted in the outer socket, and an intermediate socket mounted in the outer socket. The outer socket has a plurality of drive blocks and a plurality of retaining grooves. The inner socket includes a first base, a plurality of first driving sections, and a plurality of first openings. The intermediate socket includes a second base, a plurality of second driving sections, and a plurality of second openings. Thus, the inner diameter defined between the first driving sections is smaller than that defined between the second driving sections by 2 mm, and the inner diameter defined between the second driving sections is smaller than that defined between the drive blocks by 2 mm, so that the inner socket, the intermediate socket and the outer socket co-operate to operate three successive sizes of nuts.
