Abstract
A load indicator partly collapses under a predetermined compressive load to provide visual and tactile indications that such predetermined load has been reached or exceeded. The indicator has a longitudinal axis, opposite ends, an outer surface and a central cylindrical hole opening outwardly at the opposite ends. A circumferential groove in the outer surface intermediate the ends divides the indicator into first and second integral parts that move toward one another under a predetermined compressive load by collapsing the groove. A recess surrounds the hole at one end of the indicator so that the surface area of the one end is substantially smaller, and spaced outwardly further from the longitudinal axis, than the surface area of the other end.
