Abstract
Through bolt connection for unilaterally accessible locations. The through bolt has a cylindrical head disposed eccentrically to the centerline of the bolt by a measure e, and a sleeve disposed likewise eccentrically to the sleeve centerline by a distance e. The bolt is received in the sleeve and together they are thrust into the through hole in the parts to be fastened. Head and sleeve are of the same diameter, so that they can be inserted together head-first in the through hole in one single position relative to each other. After the bolt head is located outside the through holes, the bolt is rotated through an angle of 180.degree. to the other side so that now, owing to the eccentricity, the head catches over the edge of the through hole and its bearing surface is in contact with the surface on the inaccessible side. In this position, a nut with washer may be screwed on and tightened with the sleeve performing the function of a locating pin.
