Latest Patents

One of Sharp's latest patents is the "Self-indicating direct tension indicator," which features a direct tension indicating (DTI) washer. This innovative washer includes an annular body with one or more U-shaped horseshoe protuberances. The design incorporates a central hole, a circumference, an outer edge, a first face, and a second face opposite the first face. The horseshoe protuberances are integral to the annular body and are struck and partially sheared to project from the first face, leaving corresponding indentations on the second face. Additionally, an indicating material is encapsulated within the area defined by each horseshoe protuberance.

Another notable patent is the "Direct tension indicating washer with offset protuberances and indentations." This washer also features an annular body with a central hole, protuberances, and indentations. The protuberances are designed to project from the first face of the annular body, while the indentations are offset and located farther from the central hole. This design enhances the strength of the washer, making it suitable for use in joint assemblies with enlarged or oversized holes.
