PURPOSE:To arrange so that finishing work may be carried out with extreme ease and at low cost by filling viscous resin into a concave part with a frame and drying and curing the resin. CONSTITUTION:A concave part 4 with a frame 3 is formed on the upper surface of a head 2 of a decorative screw 1 and either the upper edge 3a of the frame 3 is caused to extend toward the interior or a concave part 4 or a convex part 5 is formed inside said frame 3. Further a viscous resin 6 containing a curing agent is filled into the concave part 4, and then is dried and cured. In this way, the falling-off of the resin can be prevented. For instance, epoxy resin is used as a viscous resin 6, tinted granule-shaped substance 7 is mixed into the resin 6 and a reflective plate 8 is fitted at the bottom of the concave part 4 so that the tinted granule-shaped substance 7 can be seen more clearly. Thus it it possible to enhance a decorative effect of decorative screws at extremely low cost. |
