Dowel-nail - reliable fastening

Today, the construction industry uses a huge 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.

Currently, due to its versatility, this is the most popular hardware product for fasteners. It is used if necessary to fix anything on any solid support, even in concrete. The dowel-nail is indispensable for the performance of heat insulation work, the construction of ventilation, electrical installation.

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:

• For mounting gun;

• For hammering.

In the first case, it is a steel sharp rod, which has a wide hat and is equipped with a special washer. A mounting gun with a shot can drive the dowel-nail into any surface, even in a metal construction.

Use of fasteners

Depending on the material of the base and the conditions under which the operation will take place, 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 bonnet is used. Its design does not allow the heat to escape through the mounting hole.

The most important advantage is that this product can be used to fix different insulation materials on any surfaces, be it concrete, natural stone or solid brick. In this case, such a material can be used as a heater:

• Styrofoam;

• Polystyrene;

• bung;

• mineral wool;

• polyurethane.

All of them are easily fixed on a solid base with a dowel-nail, but they do not break at all and do not crumble. This type of fasteners are also called façade, as it is most often used for warming 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 stains and, despite the negative influence of water, will serve for a very long time, not succumbing to destruction.

Varieties of this fastener

The dowel-nail assembly is of two types:

• threaded;

• Without thread.

The first variety 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 the secret dowel-nail includes a body and a screw, and also there is 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, for various wooden elements, for example, plasters for plaster or door and window frames.
