A method and apparatus for determining fastener axial loading includes a fastener insert having an arched bottom surface, which deflects correlative to the level of axial loading. A load indicating mechanism determines axial loading by measuring the amount of deflection experienced by the arched insert. In addition, the arched insert stores elastic energy that is added to the overall elastic energy of the fastener, thereby aiding the fastener integrity during use. A graduated load gauge is moveable to engage a load reference pin with the degree of movement corresponding to the degree of loading experienced by the fastener insert.
