ABSTRACT:
A special kind of fastening device is disclosed. The fastening device of the present invention comprises several divided washer sections and a guide wire which are to be used in conjuction with a blind rivet or a bolt. This fastening device is used in order to place the washer on the back of a wall for fastening a bolt, etc., in the case where the said back of the wall is inaccessible in usual manner. Generally the divided washer sections are of the shape of a parallel-elliptical form or a parallelogram, and therefore, they can be passed easily through a small hole. After passing through the small hole, they can be assembled into a form of a nut, if the guide wire is pulled forward which is connecting through all the divided washer sections.
