Direct tension indicating washer with offset protuberances and indentations
Abstract:
A direct tension indicating washer including an annular body with a central hole, one or more protuberances, and one or more indentations. The one or more protuberances are integral with the annular body, and struck and partially sheared from the annular body to project from a first face of the annular body and leave the one or more corresponding indentations in a second face of the annular body opposite the first face. The one or more indentations are offset from the one or more protuberances and located farther from the central hole of the annular body than the one or more protuberances. By offsetting the protuberances and indentations, the washer is strengthened and is more suitable for use in joint assemblies having enlarged or oversized holes.
