Abstract: A fastener assembly includes (a) a fastening member that includes an out-of-round portion centered about a longitudinal axis and configured for engagement with a torque-transmitting tool, a frustoconical load-bearing surface that extends radially outwardly from the longitudinal axis, and a threaded portion that is centered about the longitudinal axis; (b) a metallic, frustoconical thrust washer having a concave surface positioned adjacent to the load-bearing surface of the fastening member, and a convex surface; and (c) a pressure ring that includes a flange, a frustoconical load-bearing surface formed by the flange and positioned adjacent to the convex surface of the thrust washer, and a frustoconical undersurface oriented to contact a complementary depression in a workpiece.

Abstract: A flanged wheel fastener includes a fastener body having a threaded portion, a load-bearing surface, an out-of-round surface and a flange situated between the load-bearing surface and the out-of-round surface. A cap is disposed over the out-of-round surface and the flange, and an edge portion of the cap is bent around the flange to retain the cap on the fastener body. All portions of the cap are spaced axially away from all portions of the bearing-surface, and the cap is free of welding or adhesive attachment to the fastener body.
