How to choose a screw for drywall?

Drywall is the most practicalbuilding material. This raw material, as a rule, is used for plating and leveling walls, as well as for making partitions. Drywall sheets have excellent technical properties, besides their cost is low. 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:

• Fasteners made of carbon steel withphosphated treatment. They are used to install a material with metal profiles (a thickness of not more than 0.9 mm). Screws for gypsum cardboard of this type are produced mainly with a thread of "two-jaw" shape with a sharp tip, the head is hidden (with a cruciform spitz).
• Elements for fastening sheets using metal profiles (up to 2 mm). It is made from the same kind of materials, but the thread is made with a frequent step.
• Self-tapping for gypsum board with profilesmade of wood. 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.
