83 Locking nut with multiple thread forming leads US266525 1988-11-03 US4934859A 1990-06-19 Stephen J. Dixon; Michael D. Marvell
An improved fastening nut is disclosed which is secured to an unthreaded stud which is inserted through a central bore in the nut. The bore includes a guide and retaining splines which provides alignment guidance during sliding insertion of the stud into the bore. The guide splines preferably has an annular configuration with an inner diameter slightly larger than the diameter of the stud so that the initial insertion of the stud does not produce significant frictional resistance. The bore of the nut further includes a plurality of helical threads, preferably twin leads having equal pitch, which are disposed in the bore axially distinct from the guide and retaining splines and terminate within the bore adjacent the guide and retaining splines. The internal helical threads have a crest diameter smaller than the stud diameter and also projects radially inwardly into the bore further than the guide and retaining splines. The helical threads cold-form mating thread impression into the periphery of the stud and the resulting thread impression obstructs any vibrational retraction of the guide and retaining splines to promote retention of the nut on the stud.

PROBLEM TO BE SOLVED: To provide a fastening method and a fastening structure for fastening in which a low-cost screw is used without using a special fastening device or tool to restrict cost, and in which a gap conventionally generated after fastening is eliminated to prevent relative position change between both members by aging. SOLUTION: In this fastening structure 10, a first and a second members 11 and 12 are fastened to each other. A hole 17 is formed in the second member 12, and a cylindrical projection 14 is integrally formed with the first member 11. The cylindrical projection 14 is inserted into the hole 17, and in this inserted state, to the cylindrical projection 14, a fastening member 13 having a screw part 13c larger than the smallest inner diameter of the projection and smaller than the diameter of the hole 17 in the second member 12 is driven in its axial direction. As the fastening member 13 is thus driven into the cylindrical projection 14, the cylindrical projection is swollen diametrically outward, so that the outer circumferential surface of the cylindrical projection is pressed against the circumferential wall of the hole 17 in the second member.
