Abstract
A direct tension indicator plate, washer assembly, and fastener assembly. The plate includes an annular array of circumferentially-spaced legs extending radially outwardly from a hub, wherein each leg includes a foot portion oriented at least partially in a circumferential direction. The washer assembly includes an indicator plate carried by a washer plate having an annular array of protuberances projecting from a surface, a portion of the indicator plate being carried on the protuberances. The fastener assembly includes a fastener having an axially facing surface positioned against an annular portion of an indicator plate to sandwich the annular portion between the axially facing surface and an array of protuberances of a washer plate, wherein, when the fastener is fastened against the washer plate placing the indicator plate in compression with the washer plate, the array of legs are displaced radially outwardly.
