A two piece, resilient plastic assembly for decoratively covering the head of an installed fastener such as a screw or the like. The assembly comprises a resilient base member adapted to be held by the fastener or screw upon a planar portion of a workpiece. A resilient anchor member includes a planar, flange like base of generally circular cross section having a central orifice defined therein through which a screw or fastener passes, and an integral peripheral rim having an external surface upon which a plurality of radially spaced apart petals are integrally formed. A cup-like, resilient plastic cover plate adapted to be snap-fitted upon the anchor includes a generally convex top portion and a peripheral downwardly projecting rim. The cover plate rim includes a snap fit groove into which the anchor petals are received. This snap fit groove is separated from a lower expansion groove by an apex, and when the cover plate is pushed upon the anchor, the cap rim is expanded and the petals are slightly compressed by the compression groove. The anchor semipermanently secures the cover plate when the petals subsequently occupy the the snap fit groove, the geometry of which conforms generally to the profile of the petals.
