| 61 | Thread cleaning nut | US222561 | 1988-07-21 | US4889460A | 1989-12-26 | Curtis L. Laidlaw; Bradley J. Brewer |
| 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. | ||||||
| 62 | Retaining nut for MacPherson strut suspension assembly | US475893 | 1983-03-16 | US4599021A | 1986-07-08 | Kenneth D. Kloster |
| This invention relates to an improved self-threading unit which can be utilized to hold a replacement shock absorber within the cylindrical shroud of a vehicular suspension system commonly referred to as a MacPherson strut suspension assembly. The nut includes a generally cylindrical main body portion having a tapered thread forming portion on the inner wall thereof. The thread forming portion is adapted to roll form buttress-type threads on the upper end of the cylindrical shroud. The upper end of the main body portion includes a top wall having an annular bushing mounted therein for receiving the shock absorber piston rod and centering the nut as it is rotated onto the cylindrical shroud. The top wall is provided with channels extending radially outwardly from the bushing such that, in the event the shock absorber bottoms out, any liquid which may have accumulated on the top wall of the nut, will be evacuated outwardly and will not be forced into the shroud through the bushing. | ||||||
| 63 | Method of forming a preformed groove cutting fastener structure | US3683438D | 1970-10-22 | US3683438A | 1972-08-15 | TINNERMAN GEORGE A |
| A fastener structure is formed by swaging groove cutting or self-tapping ribs or threads in the wall of an aperture, so the ribs will cut a groove or grooves in a stud rotated in the aperture. The walls surrounding the aperture are first deformed to provide helicoidal surfaces bordering the end of the aperture, and the wall is then swaged from the inclined edge to form a rib or thread from each surface of uniform height, or tapering in height according to the angle of the helicoidal surfaces. The ribs may be formed at each end of the aperture, and the ribs or threads may also be formed to lie on the same helical path, so that the fastener may cut a single groove on a smooth shank or may engage a threaded shank. A deflected portion on each rib provides frictional resistance to rotation of the fastener.

| 64 | Extruded thread-cutting nut | US3557655D | 1969-07-03 | US3557655A | 1971-01-26 | COE WILLIAM H |
| An extruded thread-cutting nut for the forming of threads on an unthreaded post or stud which is a one-piece nut having an extruded body provided with internal threads therein, a body flange integral with and positioned at one end of the extruded body, and a face flange parallel to and joined to the body flange by a short sidewall. The face flange is provided with a central aperture aligned with the nut body and incorporates therein a helical thread provided with one or more cutting edges. An unthreaded stud first engages the cutting edge and thread in the face flange to form the thread and then engages the interior threads of the nut body.
