A tool holding apparatus having a socket holder and at least one retaining knob, comprising: the socket holder comprising an elongated body and at least one channel; the retaining knob comprising a male body, a pedestal, and a base; the channel traversing into the elongated body; the channel being extended along the elongated body; the male body being adjacently connected the pedestal; the base being adjacently connected to the pedestal, opposite of the male body; the base and the pedestal being slidably engaged within the channel; the male body being externally positioned to the elongated body; the male body being formed into a cylindrical body; the channel comprising a channel base, a first channel wall, and a second channel wall; the channel base being positioned parallel to a top surface of the elongated body; the first channel wall and the second channel wall being oppositely positioned of each other about the channel base; the first channel wall and the second channel wall being extended from the channel base to the top surface. the first channel wall and the second channel wall each comprising a top linear section, a top curve section, a bottom linear section, and a bottom curve section; the top linear section being positioned perpendicular to the top surface; the top curve section being adjacently positioned to the top linear section; the bottom linear section being adjacently positioned to the top curve section, opposite of the top linear section; the bottom curve section being adjacently positioned to the bottom linear section, opposite of the top curve section; and the top linear section and the bottom linear section being positioned parallel to each other; the cylindrical body being connected to the pedestal; the base comprising an annular body and at least one locking riser; the at least one locking riser being radially positioned around the annular body; the at least one locking riser being perimetrically connected around the annular body; the male body, the pedestal, and the base being formed as one piece; the pedestal being delineated into a circular body; the circular body being rotatably engaged in between the top linear section of the first channel wall and the top linear section of the second channel wall; characterized in that the at least one locking riser is selectively engaged in between the top curve section and the bottom linear section of the first channel wall and the top curve section and the bottom linear section of the second channel wall; and the annular body being engaged in between the bottom linear section and the bottom curve section of the first channel wall and the bottom linear section and the bottom curve section of the second channel wall. the socket holder comprising an elongated body and at least one channel;
