Screws
Typical screws open a plastic surface filling in a whole in which a screw has been placed. In this way they ensure stable fixing on which one may hang particular items (cupboards, pictures, etc.). Special bolts that are used for joining two elements in a firm and stable way are also known. There are many kinds of bolts: used for wood, concrete, plastics or metal plates. The last ones are commonly used for joining not very heavy elements with metal plates (e.g. fixing upholstery to a motor-car body or the inside equipment in motor industry).
