An adjustable spacer made of plastic for securing two plate-shaped components together with variable spacing, including an anchoring part adapted to be inserted into and secured in a hole of first one of said components and having a cylindrical hollow shaft with a threaded portion on its internal surface and a spacing screw part having a threaded shaft that can be screwed into the hollow shaft of the anchoring part to adjust the spacing between the two parts. The spacing screw part has a supporting head on its upper end and on its lower end below the threaded shaft an expanding stem made up of a plurality of separate downwardly extending legs connected at their upper ends to the threaded shaft. A through-hole extends through the screw part that tapers in the expanding stem to a narrower hole for receipt of threaded member at least one axis-parallel rib is provided on the external surface of each leg. In addition, a plurality of axis parallel grooves are provided on the internal surface of the hollow shaft of the anchoring part below its threaded portion so that when a threaded member is screwed into the through-hole of the spacing screw part to secure the second plate component to the supporting head of the spacing screw part, the grooves will receive the ribs of the legs of the expanding stem in a positive locking manner.

Adjustable spacer

A plastic button having a tiltable button cap (1) with a rotationally symmetrical bottom part (3) that can be riveted to a carrier cloth (5) by means of a tack (6). To provide a permanent connection between button cap (1) and bottom part (3) even under frequent tilting motions, there is formed on button cap (1) a hollow shank (2) that terminates at its lower end in an inwardly projecting annular flange (8). The bottom part (3) made separate therefrom has, at is upper end, a conically tapering collar (10) which can be driven into hollow shank (2), with elastic expansion of annular flange (8), and which, in the joined together state, engages with its shoulders (11) behind the annular flnage (8).
