Abstract
A seal bolt includes: an elongate and electrically conductive part with a portion extending between first and second locations lengthwise of the bolt; an electrically conductive layer that, between the first and second locations, is spaced from the elongate part; an electrically insulating layer that, between the first and second locations, is disposed between the conductive layer and the elongate part; and structure that electrically couples the elongate part and the conductive layer at a third location, the second location being between the first and third locations. In one configuration, the insulating layer includes aluminum oxide. In another configuration, the conductive layer is one of an amorphous metal and stainless steel. In still another configuration, the conductive layer includes a strip that, from the first location to the second location, has a width less than a circumference of the elongate part.
