Define expected mode of operation of the construction within which you intend to use the dowels. For use of the design inside the room there is a fundamental difference in the materials used for the production of dowels – the main materials today are nylon and polypropylene. All external construction, the operation of which will be held in more severe weather conditions require a more responsible approach to the material, so for outdoor use it is better to apply anchors of more resistant to external temperature influences, the polyamide nylon.
Determine the type of the surface, which will have to bury the dowel. For solid walls using spacers or activity dowels; to hollow, hollow or laminated wall suitable anchor dowels. In addition, there are also a number of anchors for special purposes. It anchors for drywall, sheet metal, surfaces, façade and others.
Determine the degree of the load, which will test the design in place of hardware - this will depend on the type and thickness of the dowel and also the magnitude of its penetration in the wall or structure. The General rule is that the more the load will be to use a fixing unit, the deeper must be fit and more powerful himself dowel. Typically, create hard mount using dowels with a diameter of 8-10 mm, and bury them in 30-100 mm depending on the thickness and heaviness of the attached design. The most responsible are considered a fastener in which the load acts on the dowel vertically or horizontally on a break. In that case, when the load on the dowel acts vertically downwards, it is also important to take into account the device itself plugs – push-in dowel should contain a special external notches, reinforcing the grip and the spacer antennae or wings.
Drill a hole under the concrete plug. This is done so that the dowel can be driven into the hole with some force. Typically, the diameter equal to the diameter of the drill hole or is slightly smaller. For greater strength of attachment of the dowel in the hole you can use a glue such as PVA, after brushing them with the dowel. In this case, use the screws or the screw after the glue dries.
For high-quality fasteners, in addition to well-chosen anchors, it is equally important to choose the right size screws or bolts, that he, without breaking the dowel, tightly held structure. For spacing of dowels is the most optimal is the use of screws. Their size should be chosen taking into account the thickness of the attached surface.
The hole in which the dowel is hammered, must be cleaned of dust and debris around him should be free of cracks and chips.
Advice 2: How to mount a dowel for drywall
Plaster wall is different from the usual, and to secure to her shelves or cabinets need to use special anchors. Very much depends on what is the weight of the fastened element, an incorrect calculation can lead to the fact that the Cabinet will fall, pulling out a piece of plasterboard of the wall.

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.
