ABSTRACT:
A blind bolt comprising a headed bolt with a male screw at the side opposite its head having an external diameter which can be inserted into through-holes of architecture members to be tightened; a rotating washer made of a cylindrical member having an external diameter which can be inserted into the through-holes of architecture members, and having on both end surfaces slopes in parallel to each other each of which has a longitudinal diameter larger than that of the internal diameter of each of said architecture members; and a nut which is screwed to the male screw. Thus, the blind bolt can be inserted into through-holes of architecture members from one side and also can be nut-tightened from the same one side thereby tightening the architecture members.
