How to choose a screw for drywall?

Drywall is the most practical building material. This raw material, as a rule, is used for sheeting and leveling of walls, as well as for making partitions. The sheets of drywall have excellent technical properties, besides the cost is not high. The installation of this material is quite simple, it can be carried out in a short time. For fastening sheets the most suitable device is a screw for plasterboard. Let's consider the basic moments of the selection of this element.

Types of screws

Plasterboard sheets are installed using profiles that are made of different materials. Depending on which raw materials these elements are made of (metal or wood), the following types of gypsum board fixtures can be provisionally identified:

• Carbon steel fasteners with phosphated treatment. They are used to install a material with metal profiles (thickness not more than 0.9 mm). Screws for gypsum cardboard of this kind are produced mainly with the thread of a "two-jaw" shape with a sharp tip, the head is hidden (with a cruciform spire).
• Elements for fastening sheets using metal profiles (up to 2 mm). It is made from the same type of materials, but the thread is made with a frequent step.
• Self-tapping for gypsum board with the use of wood profiles. It is made of steel with phosphating surface. The end is an acute, countersunk head, the shape of the thread with a large step "single-pass". It is also called a "drywall-wood" screw.

How to choose this device?

When choosing this type of fixing of gipsokartonnyh sheets can be guided by this information:

• It is necessary to take into account such parameters as size, used raw materials and threaded connection;
• A screw for a gypsum board, as a rule, is issued in length in a range 9,5-25 mm, the recommended size - 16 mm;
• These elements are made in the thickness of 0.25-0.48 cm, the optimal version - 3.5 mm;
• The size of the cap also plays an important role, it is better for gypsum plasterboard to choose a screw with a small upper part, so the fastening points after the finishing works will be less noticeable.

Helpful Tips

When installing gypsum cardboard, perhaps this information is useful:

• Before starting work, make sure that the wiring is correct;
• Installation must begin with a corner of the structure;
• Noise- and heat-insulating materials must be laid before installation;
• The step of fixing the sheets with self-tapping screws should not be more than 20 mm;
• Installation is best done first along the perimeter, and then in the center.

Self-cutters for gypsum board (the price for these elements ranges from 200-1100 rubles) are very convenient for fixing this kind of material. They provide a strong and inconspicuous connection, installation with these devices does not require much effort and cost. The service life of self-tapping screws, as practice shows, is long, since in the production of them, high-quality raw materials and time-tested technologies are used.
