Abstract: Изобретения могут быть использованы для заделки трещин в литых деталях. В резьбовое отверстие, выполненное в детали в зоне расположения трещины, ввинчивают штифт с головкой и резьбовым хвостовиком. По меньшей мере один из витков резьбы хвостовика имеет вершину, впадину и верхнюю поверхность. Образующая этой поверхности расположена по отношению к плоскости, перпендикулярной оси штифта, под углом больше 0°. Между головкой и хвостовиком расположен ограничитель осевого перемещения штифта, контактирующий с материалом детали в зоне трещины. Верхний край вершины витка резьбы хвостовика смещен относительно нижнего края соседней впадины вдоль оси штифта по направлению к головке. Находящаяся на наружном диаметре резьбы отверстия часть каждого витка смещена относительно остальной части по направлению к наружной поверхности материала. При ввинчивании штифта в резьбовое отверстие и взаимодействии его ограничителя с резьбой отверстия возникает усилие стягивания противолежащих сторон трещины. В результате обеспечивается полное восстановление прочностных свойств треснувшего материала. 2 с. и 26 з.п. ф-лы, 32 ил.
