A body is provided forming a handle. A pair of complementary jaw members fit within the body and move longitudinally therein. The jaw members are configurated at their outer ends so as to be complementary and together to form a nut engaging configuration. Cam surfaces are provided on the insides of the body in a position to engage surfaces of the jaw members for camming them toward each other when a nut is engaged by the jaw members and a force is applied in a direction toward the nut. The jaw members move inwardly with respect to the body and are cammed towards each other to tightly engage and hold the nut. Preferably, the jaw members are pivoted together within the body and a spring is provided to normally urged them outwardly.
