Preventing damage to a metal component or reducing manufacturing assembly steps. An initial channel, defined by an inner surface, is formed through the metal component. A bushing is placed into the initial channel, the bushing having an outer surface and an inner channel. An interference fit is created between the outer surface and the inner surface. A final channel is formed through the bushing. In forming the final channel, material is removed from the bushing to increase a size of the inner channel to be suitable to receive a fastener and such that the inner surface of the metal component remains unexposed within the final channel. The final channel extends through a second component. A fastener is placed into the final channel to attach the metal component to a second component, wherein electrical magnetic effects occur between the fastener and the bushing.
