Abstract
A cylindrical device for removing nuts in recessed locations, comprised of a hollow cylindrical body with physical modifications (lugs, grooves, abrasions, indentations) to one or both ends of the cylinder; cylinder can be made from any firm material that can withstand torque forces applied thereto. The cylinder length is determined by the depth of the recess and the hollow diameters are determined by the internal size of the recess and any rod or other protrusion that must be accommodated within the cylinder to access the nut. The device includes no separate moving parts which may freeze or jam and may be utilized in conjunction with common pliers or other gripping tools.
