Abstract
A direct tension indicating (DTI) washer. The DTI washer has an annular body and one or more U-shaped horseshoe protuberances. The annular body includes a central hole, a circumference, an outer edge, a first face, and a second face opposite from the first face. The horseshoe protuberances each have a height, an apex closest to the central hole, and an opening directed toward the outer edge. The horseshoe protuberances are integral with the annular body and struck and partially sheared from the annular body to project from the first face of the annular body and leave one or more corresponding indentations in the second face of the annular body. The horseshoe protuberances may be radially offset from their corresponding indentations. An indicating material is initially encapsulated and contained within the area on the first face defined by each of the horseshoe protuberances.
