Shim elements or spacers designed for use in side-by-side relation between structural steel beams and hanger assemblies which are united by means of pairs of variably-spaced bolts. Each shim element comprises a flat, U-shaped rectangular plate element having leg extensions of different widths and lengths and a central recess adapted to receive a structural bolt. The invention involves providing a universal shim element which is useful in pairs in any one of three different distances by which structural steel-uniting bolts are conventionally separated.
