Patent ID: 8561742

Claim:
A molded metal insert adapted to attach and fix a plastic part to a vehicle structure, the insert comprising: a cylindrical molded metal body having inner and outer diameters and upper and lower molded end portions, the upper and lower end portions collectively defining the outer diameter, each end portion being continuous about a circular periphery, the inner diameter defining a passageway sized to allow a threaded portion of a fastener to extend through the passageway and below the lower end portion for threaded attachment to the vehicle structure, the upper end portion providing a seat for a head of the fastener; and a plurality of anti-rotation metal teeth integrally molded with and extending radially outwardly from the cylindrical metal body between the inner and outer diameters and integrally molded with and extending linearly between the upper and lower end portions wherein the insert has an irregular tooth distribution and the teeth are sized and sides of the teeth are oriented or shaped to permit the insert to be die cast in a cavity formed between first and second parts meeting at a plane of a two-part mold without breaking the teeth during movement of the first part in a first direction perpendicular to the plane and movement of the second part in a second direction opposite the first direction perpendicular to the plane during opening of the mold and wherein each tooth adjacent to but spaced from the plane has first and second side surfaces wherein each of the first side surfaces is substantially perpendicular to the plane so that none of the adjacent teeth break during opening of the mold and wherein each of the teeth extends linearly in a direction perpendicular to the first and second directions the entire distance between the upper and lower portions of the metal body.
