A holder system for interchangeable socket members comprises at least one socket receiving member, a base, and a lock member. The socket receiving member has a central axis and nub for engaging a socket. The socket receiving member is also removably attached to the base. The lock member has a lock stop, and the lock member is removably insertable into the receiving member. The lock member also prevents the nub from releasing the socket receiving member. The base and the lock stop prevent movement of the lock member in either direction along the central axis.
