Abstract
A vibration resistant nut is provided for attaching a working surface to a threaded stud, the stud extending through a hole defined through the working surface. The nut includes an annulus for receiving the stud. The annulus includes a cylindrical portion and a tapered terminal end portion for being received in the hole. The tapered terminal end portion extends from the cylindrical portion. The tapered terminal end portion has an outer surface that narrows diametrically from the cylindrical portion. The nut includes a head extending from the cylindrical portion of the annulus opposite the tapered terminal end portion, the head having outer engagement surfaces for engaging a tool for rotation of the nut, the head having a threaded interior for engaging threads of the stud.

A vibration resistant nut for attaching a working surface to a threaded stud, the stud extending through a hole defined through the working surface, the nut comprising:
- an annulus for receiving the stud, the annulus including a cylindrical portion and a tapered terminal end portion for being received in the hole, the tapered terminal end portion extending from the cylindrical portion, wherein the tapered terminal end portion has an outer surface that narrows diametrically from the cylindrical portion;
- and
- a head extending from the cylindrical portion of the annulus opposite the tapered terminal end portion, the head having outer engagement surfaces for engaging a tool for rotation of the nut, the head having a threaded interior for engaging threads of the stud.
A wheel hub assembly comprising:
- a central hub;
- a flange mounted on the hub, the flange having multiple holes;
- multiple studs each affixed to and extending from the hub, each stud having an outer extending portion with external threads;
- a flange for mounting to the central hub, the flange having multiple holes each for passing therethrough the outer extending portion of a respective stud;
- and
- multiple vibration resistant nuts for cooperatively securing the flange to the hub by each engaging a respective stud of the multiple studs passed through a respective hole of the flange, each of the multiple vibration resistant nuts comprising:
- an annulus for receiving the respective stud, the annulus including a cylindrical portion and a tapered terminal end portion for being received in the respective hole of the flange, the tapered terminal end portion extending from the cylindrical portion, wherein the tapered terminal end portion has an outer surface that narrows diametrically from the cylindrical portion;
- and
- a head extending from the cylindrical portion of the annulus opposite the tapered terminal end portion, the head having outer engagement surfaces for engaging a tool for rotation of the nut, the head having a threaded interior for engaging external threads of the respective stud.
