Abstract
PURPOSE: To make a judgement visibly capable of the axial force inducted into an axis of the high-strength bolt, by means of using a dished spring washer for a jointing of the high-strength bolt to deform the shape of the dished spring washer.
CONSTITUTION: A dished spring washer 1 is shaped likely to lay a plate upside down with a circular hole provided in its center. A use of said washer 1 for the washer of a high-strength bolt 2 provides a gap between said washer 1 and bolt 2 befoer tightening the high-strength bolt 2, and the process of its tightening flatly deforms the shape of said washer 1, thus capable of visibly judging the condition of tightening. In order to operat a visible judgement of the axial force further accurately, a method of inserting an inversion washer of very thin plate, similarly shaped to the dished spring washer 1, into between the dished spring washer 1 and the high-strength bolt 2 may be available.
