In order to secure a light frame or a shelf from plywood and screw a regular screw with a screwdriver.
If you need to hang on drywall is not a very difficult subject, prepare the dowel-screws. Use an ordinary drill or screwdriver and screw the screw in a designated location, usually it is easily screwed into sheets of any thickness. However, if the thickness of the leaves more than 15 mm, pre-drill the hole. Different length dowels, screws, represented in the stores to pick a size that it is not performed on the reverse side of the sheet.
To get a more reliable fastening in drywall, buy at the hardware store dowel butterfly. On the reverse side of the sheet by tightening it expands and forms a stop. First, drill a hole in the wall the same diameter as the dowel.
Insert the butterfly, but not completely, leave a few millimeters, to be able to get hold of the dowel with pliers or pliers. Gradually tighten the screw (if you use a screwdriver, turn the small momentum).
Wait for the moment when the butterfly starts to open the wings and push a dowel fully into the hole, removing the pliers (to rotate it will not be). Then gently tighten the screw and, when he will cease to scroll, make a few turns.
In order to hang a heavy chandelier on the ceiling, use a folding spring-loaded dowel. Drill a hole in the drywall construction (diameter specified in the instructions to the fastener), hold by hand folding the wings of the dowel and insert it into the hole.
When the wings reach the void on the reverse side of the sheet, thanks to the spring mechanism, they will be revealed and will secure the fasteners. Tighten the screw to the required position with a screwdriver or a drill.
