For fixing many building materialsuse special threaded fasteners. Self-tapping screws for a profile for drywall come in various types and sizes. Their choice depends on the type of sheets and the place of installation. Knowing which screws for fixing drywall are best suited, you will not spoil this material and provide a strong grip.
The self-tapping screw represents a type of fixingproducts, which is equipped with a wide flat head and a sharp threaded rod. The product is made, as a rule, from steel as it as much as possible meets the parameters of rigidity and durability.
Screws, depending on what material they are intended for, are divided into the following types:
For the production of this product the following types of steel are used:
Также можно отдельно выделить саморезы, покрытые strengthening compounds. Most often, self-tapping screws and dowels used for warming are galvanized for better resistance to aggressive external environment. Fasteners for mounting the frame are covered with oxides or phosphates, they are painted black. Products have good stiffness.
Import and domestic manufacturers of fasteners, as a rule, adhere to the standard parameters in their manufacture.
The length of products varies.It can be 16-152 mm. The normal diameter of the screws ranges from 3.5 to 4.8 mm. If you are having difficulty choosing, you can consult with the sales manager.
Before you go to the store, write down the basic parameters of the purchased sheets of drywall.
Screws for drywall profile can be withoutspecial effort to fix their own hands, because for their installation does not need special tools. However, the installation process is much faster when using a screwdriver. The most important thing is to make the right choice of fasteners. It is important to remember that it is necessary to use different parts for the metal and wood frame.
For wood, sheets are fastened with appropriatewood screws, which are predominantly shorter. Their length is up to 24 mm. For a metal base, screws for a drywall profile are up to 32 mm. However, such a length is not always sufficient for securing individual sheets. For example, if you need to attach two levels of cardboard to the frame, then you should choose the size of 33–35 mm self-tapping screws.
In order to screw in it was easierThey are produced with a different frequency of thread (frequent or rare). Rare is more preferable, because it allows to fix the material more reliably. However, it should be remembered that with high brittleness and low quality of the slabs, coarse thread can lead to mechanical damage.
Try as objectively as possible to assess the type of drywall used.
The key indicators also include the thickness of the rod. Typically, this parameter ranges from 0.6 to 0.8 mm.
For fixing to drywall screws are usedspecial types of products having a carob type head. When fasteners, they are buried in the surface, thereby ensuring the evenness of the initial coating, which is very important for the subsequent completion of the correct finishing of the coating.
In order to choose the right type of parts for fixing drywall or profile, you must first familiarize yourself with the distinctive features of each type.
Before you calculate the total consumptionfasteners, you should know how many screws are needed for 1 sheet of drywall. It must be remembered that for the connection of different types of materials use a different number of fasteners. The pitch for wooden profile screws is 35 mm, 30 millimeters, for a metal one - 30 mm, in some cases deviations of several millimeters can be made. It is also necessary to consider how many layers of cardboard will be installed: one, two or more. In the latter case, you will need to reduce the distance between some fasteners or increase the size of the parts to ensure rigidity.
Based on the foregoing, the approximate number of self-tapping screws per 1 sheet of drywall is 70–110 pieces.
After the installation is completed, theirIt is imperative to treat with special anti-corrosion compounds and then to pierce, because otherwise they will be strongly visible on the surface of the sheets after the finish. In addition, you should try not to “drown” the heads of the screws too much so that large furrows do not appear.
You can buy a self-tapping screw for panels and drywall in all hardware stores, on the market or on the Internet.
Approximate number of attachment points should becalculate in advance. Self-tapping screws, the price of which is indicated below, are most often sold in packages and have a standard number of pieces. As a rule, they are packaged in 100, 250, 300, 400 pieces. If you are working on a large area (for example, when repairing offices), you can purchase packages of even 5,000 or 20,000 pieces.
If you do not know the quality of the goods, it is recommended to buy a small bag first. At the same time it will allow to check in practice whether the thread is selected correctly.
This product must be viewed when purchasing.Recalculate the number of pieces, of course, not worth it, but check for the presence of marriage will be useful. If you suddenly find rust or knocked down threads, it is better to choose another manufacturer.
The cost of self-tapping screws depends on their type and size.The average price of one piece will be a couple of rubles. In a pack, which includes from 100 to 500 pieces of screws, one copy will cost a bit cheaper - about one ruble.
