The invention is a tool for installing Hi-Lok-type fasteners consisting of a pin component having a headed end and a threaded end with a hex recess therein, and a collar component having a threaded body and a torque-off nut. The tool has a drive head in which a rotatably driven socket is supported for driving the collar component of the fastener during a fastener installation event. A tubular key holder is coaxial with the socket and rotationally fixed relative to the drive head, supporting a hex key against rotation in an axial keyway, the hex key being engageable in the pin component hex recess to hold the pin component against rotation during a fastener installation event. A retention shaft extends coaxially through the key holder, and its forward end is threadedly connected to the key to retain the key in the holder. The key is forwardly threadedly removable from the holder keyway by rotating the retention shaft in one direction relative to the holder, and another key is threadedly replaceable in the holder keyway by rotating the retention shaft in the other direction relative to the holder. Tooling inventory is minimized by the ability to utilize only a single size key for all socket lengths and drive hex recess sizes, and by the ability to utilize only eight holder sizes to accommodate the conventional eight socket lengths, for all socket hex recess sizes.
