A self-forming socket assembly includes a socket having an operational end and a connection end. A recess is defined in the operational end and a passage is defined in the connection end and communicates with the recess. A board is rested on a shoulder in the recess and includes a central hole and multiple bores. Each bore has a gripping pin retractably inserted therein, and includes a polygonal section. A bit movably extends through the passage of the socket and the central hole of the board. The bit is positioned in the central hole of the board or positioned to protrude beyond the recess. 1.
