ABSTRACT:
A thread cleaning nut including a nut body having a central axis, first and second spaced apart faces formed on the nut body and a central aperture extending through the nut body along a central axis between the first and second faces. A screw thread is formed between the first and second faces within the central aperture wherein less than one-half of the first face is shaped as a first flat surface and more than one-half of the first face is shaped as a second flat surface inclined at an actue angle to the first flat surface. An end portion of the screw thread between the first and second surfaces is exposed to define at least one cutting tooth for cutting a path for the screw thread. The first and second surfaces intersect a third flat surface. The third flat surface intersects the central aperture at a position spaced from the central axis and it intersects the end portion of the screw thread at an acute angle to define a cutting edge of the at least one cutting tooth. Preferably, the first and third surfaces are formed by a single path, straight-line milling operation. Also, preferably, both faces of the nut body are so machined on opposite sides of the central axis.
