Abstract: A tri-lobular, all metal, prevailing torque nut is disclosed providing a cone having three locking sections, each of which extends around the threaded opening for about one-third of the surface of its thread. Each locking section provides a minimum radial distance at its center and extends with gradually increasing radial distance to the ends thereof. When the nut is threaded onto a mating threaded fastener, portions of each locking section are radially displaced from their unstressed condition to the circular shape of the mating fastener, producing frictional engagement between the nut and the fastener to resist unintentional loosening. Each locking section is arranged so that it provides a maximum resistance to deflection at its center and decreasing resistance to deflection at locations progressively spaced from the center so that excessive pressures are not developed which would tend to produce excessive wear or permanent deformation.
