Abstract: An assembly comprises two structural elements 12, 14 secured firmly to one another while a gap G is maintained between them. The assembly comprises a threaded through bore 18 in the first 14 of the two elements and an externally threaded annular bushing 20 screwed into the through bore 18 and having one end 22 projecting from one of the opposed faces into contact with the other, so as to maintain the desired gap G. A bolt 28 passing through the annular bushing 20 is used to secure the elements 12, 14 to one another. In the invention, the end 22 of the bushing 20 is tapered and is received within a recess 24 of complementary shape in the second element 12 in order to lock the bushing in position.
