Abstract
An amplified indication of the elongation of a fastener is provided for determining instantaneous loading conditions of a fastener. A load indicator is couplable to a fastener for instantaneous load measurement and includes a housing defining a fastener interface configured to removably couple the housing to a fastener. A moveable datum probe extends from the housing in contact with a datum rod anchored within an internal bore of the fastener. A first lever is pivotally mounted within the housing and is moveable in response to displacement of the datum probe. A load display indicates a degree of loading of a fastener as a function of displacement of the datum probe. A second lever can be used to further amplify the reading from the displacement of the datum probe. An inclined visual scale and a multi-faceted lens allows for viewing of loading values from multiple directions or angles.
