Abstract: A mechanics' limited-access nut starter instrument 1 may provide a precision hexagonal nut holding capability in limited-access mechanical areas commonly encountered by mechanics. Because a hexagonal recess is provided slightly undersized with respect to its intended nut size, the instrument 1 actually begins to hold a nut prior to locking with serrated locking extensions 6a and 6b. Engaging locking extensions 6a and 6b will apply a clamping pressure on the held nut. In a second embodiment of the present invention, a pistol-type tool grip may be provided for a tool (including the nut starter of the first embodiment). The pistol-grip afford better gripping and control over the tool, reducing fatigue and more importantly, reducing the risk a tool may be dropped or lost into a limited-access area. A lanyard or the like may be attached to the pistol grip to attach the tool to the wrist of the worker to prevent loss. The lanyard may also be used to hold the tool in a clamped position.
