Today in the construction industry is usedthe largest number of all kinds of fasteners. One of them is a dowel-nail. It was widely used not only on a professional level, but also in everyday life.
It belongs to the shock plugs, and the existing special thread greatly facilitates the fastening process. The mounting dowel-nail is divided into two types according to the method of use:
for mounting gun;
for hammering.
In the first case, it is a steelA sharp rod, which has a wide hat and is equipped with a special washer. The mounting pistol is capable of driving a dowel-nail into any surface, even in a metal construction.
Use of fasteners
Depending on the material of the substrate and those conditions,in which the operation will be carried out, the fastener is also selected, since the design features and properties are different for them. For example, for heat insulation work, a dowel-nail with a wide outer cap is used. Its design does not allow the heat to escape through the mounting hole.
The most important advantage is thatthis product can be used for fixing different heat-insulating materials on any surfaces, whether it be concrete, natural stone or solid brick. In this case, such a material can be used as a heat insulation material:
Styrofoam;
polystyrene;
bung;
mineral wool;
polyurethane.
All of them are easily fixed on a solid basisdowel-nail, while not completely broken and do not crumble. This type of fasteners are also called façade, as it is most often used to warm the walls of buildings. In case of permanent exposure to moisture insulation, it is recommended to choose plastic fasteners. It is most effective, because the material from which it is made, will never give rusty streaks and, despite the negative influence of water, will serve for a very long time, not succumbing to destruction.
The dowel-nail assembly is of two types:
threaded;
without thread.
The first version is screwed with a screwdriver, and it can be used many times. The second variant resembles an ordinary nail, which is driven into the body of the fastener by means of a hammer.
The design of a secret dowel-nail includesbody and screw, and also has a countersunk head. First a hole is made in the wall or in another base. Then the body is inserted into it, and in the end the screw is screwed. When the core is deepened, the expanse of the product is wedged and the anchor is thus firmly fixed.
This nail is used for fixing to hard materials, such as concrete or natural stone, to various wooden elements, for example, plasters for plaster or door and window frames.
