Drywall is the most practical building material.These raw materials are usually used for sheathing walls and alignment, as well as for making walls.Sheets of drywall have excellent technical properties, besides their cost is low.Installation of this material is quite simple, it can be done in a short time.To fix the sheets is the most appropriate tool for the drywall screw.Consider the main points of the selection element.
Types screws
sheets of drywall installed using profiles that are made of different materials.Depending from which raw materials are made of these elements (metal or wood), can be divided into the following types of devices for fastening drywall:
- fasteners made of carbon steel with a phosphated treatment.They are used to set the material of the metal profiles (thickness less than 0.9 mm).Drywall Screws of this type mainly produces thread "bifilar" shape with a sharp tip, countersunk head (Phillips spire).
- elements for fastening using sheets of metal profiles (2 mm).It is made of similar materials to the first sight, but the thread runs with frequent steps.
- Screws for plasterboard with profiles made of wood.Made of steel with phosphating surface.The end of the sharp, countersunk head, thread form a major step "single-pass".It is also called screw "drywall-tree."
How to choose an adaptation?
When choosing this type of fixture gypsum board can be guided by this information:
- should take into account parameters such as the size of the used raw materials and the threaded connection;
- screw for plasterboard, as a rule, issued in length in the range of 9,5-25 mm, the recommended value of - 16 mm;
- these elements are manufactured within the thickness of 0,25-0,48 cm, the best option - 3.5 mm;
- cap size also plays an important role for the drywall is better to choose a small screw top, thus securing a place after finishing work will be less noticeable.
Useful tips
When installing drywall may be useful, such information:
- before starting work necessary to ensure the correct supply of electrical wiring;
- installation should start with the corner of a structure;
- noise and thermal insulation materials have to be laid before the assembly;
- step of fastening sheets using self-tapping screws shall not exceed 20 mm;
- installation is best done first on the perimeter, and then in the middle.
Drywall Screws (the price of these items varies from 200-1100 rubles) is very suitable for mounting this type of material.They provide a solid and discreet connection with the installation of these devices does not require much effort and cost.The service life of screws, as practice shows, is long, because they are used in the production of high-quality raw materials and proven technology.
