A screw cover ( 100 ) for a screw hole ( 32 ) includes a stretchable cap ( 10 ), and a post ( 20 ) movably engaged therein. The cap includes an end ( 12 ) having an opening ( 122 ) and three arms ( 14 ) extending therefrom. The arms have three longitudinal slits ( 144 ) therebetween. The post has two wedges ( 242 ) slidably engaged in two of the slits. A diameter of the cap is no larger than a diameter of the screw hole, and a diameter of the post is larger than a diameter of the opening. In use, the post is interferingly inserted into the opening and enlarges the cap, which engages the screw cover in the screw hole. In removal, the post is released from the opening, and the cap returns to its original size. The screw cover can then be easily removed from the screw hole. Attachment and removal of the screw cover is easy and safe.
