Drywall is the most practical building material. This raw material is usually used for sheathing and leveling walls, as well as for the manufacture of partitions. Drywall sheets have excellent technical properties, besides their cost is low. Installation of this material is quite simple, it can be carried out in a short time. For fastening sheets, the most suitable fixture is a drywall screw. Consider the main points of the selection of this element.
Types of self-tapping screws
Gypsum board sheets are installed using profiles that are made from various materials.
Depending on what raw materials these elements are made of (metal or wood), the following types of drywall fasteners can be conditionally distinguished:
- Fastening parts fromcarbon steel with phosphated finish. They are used to install material with metal profiles (thickness not more than 0.9 mm). A self-tapping screw for drywall of this type is produced mainly with a “two-start” thread with a sharp tip, a countersunk head (with a cross-shaped spitz).
- Elements for fastening sheets using metal profiles (up to 2 mm). It is made from materials similar to the first type, but the thread is made with frequent steps.
- Self-tapping screw for drywall using wood profiles. Made of steel with phosphated surface. The end is sharp, countersunk head, thread form with a large pitch "single-start". It is also called the drywall-wood self-tapping screw.
How to choose the right device?
When choosing this type of fastener for drywall sheets, you can be guided by the following information:
- Size, raw material used and threaded connection should be considered;
- drywall self-tapping screw, usually available in lengths ranging from 9.5-25 mm, the recommended value is 16 mm;
- these elements are made with a thickness in the range of 0.25–0.48 cm, the best option is 3.5 mm;
- the size of the cap also plays an important role, for drywall it is better to select a self-tapping screw with a small upper part, so the attachment points after finishing work will be less noticeable.
Helpful tips
When installing drywall, the following information may be useful:
- before starting work, you need to make sure that the wiring is correct;
- installation must start from the corner of the structure;
- noise and heat insulating materials must be laid before installation;
- the step of fastening sheets with self-tapping screws should be no more than 20 mm;
- installation is best done first around the perimeter, and then in the center.
Self-tapping screws for drywall (the price of these items ranges from 200-1100 rubles) are very convenient for attaching this type 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 high-quality raw materials and time-tested technologies are used in their production.
