Abstract
A temporary fastener includes a grip length indicator. By machining a flattened area into a body of the temporary fastener, by engraving an scale into the flattened area, and by attaching an indicator dot visible in the groove to a moving part of an internal assembly of the temporary fastener, the grip length of the installed temporary fastener may be read directly on the scale while the temporary fastener applies a clamp-up force to a structure. By using the temporary fastener of the present invention, it is possible to determine a fastener hole length while a temporary fastener is installed. Using the method for determining a fastener grip length of the present invention enables the effective determination of the correct fastener grip length for each particular fastener hole of a large structure, such as an aircraft airframe.
