A preferred embodiment of the present invention is directed to a tool accessory case having first and second housing members pivotally connected to each other along a hinge portion and forming a tool holding cavity. A latch is connected to the first housing member and is moveable between latched and unlatched positions. The latch has a gripping structure configured for gripping the second housing member, and at least one flexure member configured to contact the first housing member and bias the latch toward the latched position. The latch also has at least one fixed hinge guide for pivoting with respect to the first housing member and with respect to the flexure member. The tool accessory case also has a receiving structure disposed on the second housing member and is configured to receive the gripping structure of the latch when the latch is in the latched position.
