Abstract: A scaled releasable fastener for temporarily joining a plurality of sheets through apertures located in the sheets has a body with a work engaging surface and an opposite surface. The body includes a longitudinal bore extending through the body from the work engaging surface to the opposite surface. A pair of laterally expandable work engaging pins are positioned in the bore. Each of the pins has a work engaging shoulder. A spreader member is fixedly carried by the body and is positioned between the work engaging pins for laterally spreading the pins apart upon retraction of the pins into the bore. An elongated element is positioned in the bore in association with the pins for moving the pins in the bore. A portion of the elongated element extends out of the body from the opposite surface of the body with the remaining portion of the elongated element located in the bore and connected to the pins. Indicia marks are located on the elongated element to be readable against the opposite surface of the body.
