A load indicating fastener comprising a load indicator, a fastener body, and a securing mechanism retaining the load indicator on the fastener body. The load indicator has integral protuberances struck and partially sheared from the load indicator to project from a face and leave corresponding indentations in an opposite face. The securing mechanism may be a member extending radially outward from the shank of the fastener body, such as a plurality of spaced apart tabs; at least one thread; at least one flare, stake, or form; a step ring; a series of bumps; a knurl; and one or more lobes. Alternative embodiments of the securing mechanism include a key-and-keyhole combination; an interference fit facilitated by a chamfer or by one or more lobes or by shaped surfaces of the fastener body and of the load indicator; one or more tack welded interconnections; and an adhesive patch. |
