Abstract
A load indicating insert visually displays fastener loading during tightening and use of a fastener. First and second levers are positioned by a connective cartridge substantially within a fastener bore to provide a compound. amplified indication of loading as a function of the elongation or deformation of the fastener. The first lever is connected at an internal pivot point of a cartridge with a lower end resting on an abutment within the fastener bore. As the abutment moves the first lever during elongation, the second lever moves relative to a visual loading scale. As the fastener is loaded and unloaded, varying elongation of the fastener causes displacement of the abutment and movement of the indicator back and forth along the load indicating scale.
