Drywall is the most practical building material. This raw material is usually used for cladding and leveling walls, as well as for the manufacture of partitions. Drywall sheets have excellent technical properties, in addition, 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 device is a self-tapping screw for drywall. Consider the main points in the selection of this element.
Types of screws
Drywall sheets are installed using profiles that are made of various materials.
Depending on what raw materials these elements are made of (metal or wood), the following types of devices for
attaching drywall can be distinguished:
- Fasteners made of carbon steel with phosphate treatment. 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 “double-thread” shape 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 of materials similar to the first type, but the thread is made with frequent steps.
- Drywall screw with wood profiles. It is made of steel with phosphating surface. The end is sharp, countersunk head, the shape of the thread with a large step "single start". It is also called a gypsum plasterboard self-tapping screw.
How to choose this device?
When choosing this type of fastener for drywall sheets, you can be guided by the following information:
- parameters such as size, raw materials used and threaded connection should be taken into account;
- a drywall screw, as a rule, is available in a length in the range of 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 choose a self-tapping screw with a small upper part, so the attachment points after finishing work will be less noticeable.
Useful 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 begin from the corner of the structure;
- noise and heat insulation materials must be laid before installation;
- the step of fastening sheets using self-tapping screws should be no more than 20 mm;
- installation is best done around the perimeter, and then in the center.
Self-tapping screws for drywall (the price of these elements ranges from 200–1100 rubles) are very convenient for fixing this type of material. They provide a solid 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.
