ABSTRACT:
The present invention multi-socket wrench includes an elongated main member with an upper area, lower area, a first end, a second end and at least two wrench units, e.g. four wrench units. Each wrench unit has an elongated dimension, and each wrench unit has only two sockets, positioned side by side thereon. Two wrench units are rotatably attached, one each at the upper and lower areas of the first end of the elongated main member. There is also a wrench unit attachment mechanism which provides for the substantial alignment of an outer positioned socket of the upper attached wrench unit with an outer positioned socket of the lower attached wrench unit. In some embodiments, sockets of the lower attached wrench unit have a diameter at least 55% the diameter of an aligned socket of an upper attached wrench unit. In other embodiments the upper attached wrench unit is fixedly connected to the lower attached wrench unit so that rotation of one of the connected wrench units causes coincidental rotation of the other of the connected wrench units. Still in another preferred embodiment, the wrench has two wrench units attached at the first end and two wrench units attached at the second end, combining to form a wrench having eight different sizes.
