Abstract

An injection molded part accommodates a threaded fastener and includes a metal insert. The insert defines a longitudinal axis and has an end face and an outer peripheral surface. A cutout extends from the end face and through the insert to permit the threaded fastener to extend therethrough. A plastic body surrounds the outer peripheral surface and has a threaded fastener contact face. The threaded fastener contact face of the plastic, body is recessed at a recessed distance below the end face of the insert which has a spring constant with respect to the longitudinal axis. The recessed distance and the spring constant are selected to deform the insert in response to a stress force applied to the end face thereof by the threaded fastener to cause a pregiven component of the stress force to be introduced into the threaded fastener contact face of the plastic body.
