ABSTRACT:
A differentially threaded bolting arrangement for bolting two machine parts together includes one or more bolts the opposite ends of which are provided with threaded sections differing in pitch, a threaded hole in one of the machine parts into which the bolt end with the greater pitch is threaded, a bore through which the bolt passes and an adjacent hollow area in the other machine part in alignment with the threaded hole, and a nut having a cylindric configuration located in the hollow area and which is movable axially but is restrained against rotation. The bolt end having the smaller pitch is threaded through the nut and as the bolt is rotated, the nut is thus caused to move axially into a forced contact with the lower end of the hollow area accompanied by a drawing together of the two machine parts. When several bolts are utilized, all of the bores and hollow areas with the nuts therein can be located in one of the machine parts and all of the threaded holes can be located in the other machine part, or the bores, hollow areas, and nut assemblies and the threaded holes can be located alternately in the machine parts.
