Fasteners for plasterboard: species and their features

Plasterboard – one of the most popular building materials. It is used to align wall surfaces, as well as for the formation of partitions and other plasterboard systems. One of its disadvantages is fragility. Therefore, you have to use special fasteners that are intended to work with such products. The right choice of fasteners will make it possible to obtain a reliable and durable design capable of withstanding significant loads.


Technical characteristics of drywall differ from the parameters of other materials. It is due to the fact that the products consist of a bulk gypsum, which is held with the help of external paper sheets. So working with a similar product should be especially careful and carefully. Today, for solving these tasks, various fasteners and write. Externally, these products do not differ from the standard tape or metal screws and consist of several main parts.


This element is not mandatory, it is used in the case when you need to create a solid grip between fasteners and plasterboard. Externally, such a product may have a different form. It is adjusted under the material in which the writer will be located. Almost always they are used when you need to fix the sheet of GLC to the wall.


Products made from metal or plastic. The form of such hardware can be different. It is determined by the fact that each of the data of the screws must withstand various loads. In most cases, they are used in a pair with a certain type of dowel.


Technically fasteners for drywall adapted in such a way as to obtain a system that mostly distributes the load as much as possible, and is also unable to destroy the product under high loads. Hardware for working with plasterboard differ in several technical characteristics. But in most cases, classic screws are used here, which fasten the tree or metal. Conditionally divided similar systems on a self-tapping screw and dowels. They are independent elements, but are often combined to create a solid connection. Mounting plasterboard sheet or work with it can be using several types of self-samples.


This self-sufficient class is the most common. Such products are conventional fasteners used to work with wood or metal. They differ only in a step of thread and color. Systems in most cases are complemented by classic plastic dowels. Use them recommended in cases where the sheet of plasterboard is fixed to a wooden or concrete base. In most cases, this implies the walls of the walls or the ceiling.


These products differ small length. In most cases, such fasteners are used to fasten the metal profile, from which all the plasterboard system is formed. A distinctive feature of the product is the presence of a kind of drill at the end of the self-press. Therefore, drilling holes under them in the metal are not necessary, as they themselves are well destroyed by this material.


Self-tapping screws are used to fasten metal parts from which the framework is formed. They have small sizes, the tip of these products is acute. Therefore, experts recommend to sew with the help of repellent metal-plants with a sheet thickness not more than 1.2 mm. In another case, these products will not be effective.

As for dowels, they also have several types.


This fastener is used to fix products with a slight weight directly on the surface of the drywall (for example, lamps, paintings). Made butterflies from special types of polypropylene. Technical dimensions of dowels may be different. A feature of this product is the presence of opening items. When screwing out the self-pressing, the dowel is compressed, forming an additional plane.


Dowel of this kind reminds self-sufficiency, since self-tapping elements are present on its outer surface. This allows you to significantly speed up the installation of such structures. Made them of plastic and metal. Use this dowel for fixing drywall to the base.


The principle of operation of this dowel is similar to a homework-butterfly. The screwing screw makes the squeeze, forming an additional support. A distinctive feature of such fasteners is the fact that it is made of metal. Therefore, Molly is able to withstand pretty high loads.


This type of clamps is the most common. This is a classic dowel, which for fixation is driven into a previously drilled hole. The presence of special spacers does not allow it to slip out of the hole. To get reliable fixation, the hole diameter should be less than the corresponding dowel size. In another case, the design will easily come out of the groove.

Fastening chandeliers and other similar suspension systems in most cases produce to the main ceiling. If you need to fix a not too heavy lamp, we use special anchor. They are equipped with carvings and complemented by various types of dowels. Technically, they can be considered a type of self-sufficiency. Often, during installation of plasterboard systems, metal auxiliary structures are used (for example, sliding corner). They are also a fasteners, but for their fixation to plasterboard use almost always previously described types of hardware.

What to choose?

The type of fastener is one of the main factors affecting the reliability and quality of plasterboard mounting. Therefore, special attention should be paid to their choice.

Buying selflessness, it is advisable to take into account a few simple rules.

  • Give preference to self-headed heads. This will make it easily drown them in the structure of plasterboard. It is undesirable to use hardware for such works that have a head in the form of a hemisphere.

  • Saws must be approached under the type of foundation. For example, in a log house, use fasteners on a tree that will easily enter the tree and secure sheet. A similar algorithm can also be used for wooden frames formed during the ceiling or walls.
  • Screw length is selected individually for a specific situation. It is important that it came into the frame of no less than 2-3 cm. This is especially true of self-tapping screws that are not complemented by dowels and are the main fixing element.

  • Main material. Almost all self-tapping screws are made of steel, but the structure of the metal may differ. The cheapest are black chain screws. They are fine withstand the load, but over time they can rust. These changes can affect the decorative finishing layer.

The choice of dowels for drywall structures is an important stage and implies an assessment of several parameters.


Today, the dowels can be used to fasten the drywall to the base or fixing other products on top of this material. If you need to attach baguette or plinth in the kitchen, then the decision can be a butterfly or drying. Dowel Molly perfectly copes with fasteners of shelves or plumbing.

Fastening technology

Screw dowel-driv not much difficulty. If you need to use other types of designs, it should be understood that they need additional space. It is due to the fact that when opening a butterfly, the protruding systems. Therefore, if a sheet of plasterboard is attached tightly to the main wall, apply such fasteners technically unreal. By the solution of such a problem are ordinary dowel-nails and a properly selected self-press size.

Load capacity

Almost all varieties are used to attach structures on top of the plasterboard. Fixation of heavy products (for example, massive chandelier, shelf, locker) is carried out only with the help of special anchors or Molly dowels. These systems are able to withstand weight up to 50 kg. Driva proven well when fixing structures weighing up to 30 kg. The most simple and unreliable are butterflies, with the help of which you can suspend the design weighing up to 11 kg.

How to calculate flow?

The amount of fasteners affects the reliability of fixation of a plasterboard ceiling or partition. Therefore, it is important before the start of work to carry out the calculation of all components to pre-purchase them. There is no universal formula for calculating samphs or dowels. Recent elements are not used without hardware. Having calculated the amount of self-tapping screws, you can learn the volume of auxiliary products.

To correctly calculate the volume of hardware, one should be headed by several rules:

  • Take into account the fastening step between self-drawing. The optimal is the distance of 35 cm. Please note that end fasteners can not be recorded close to the leaf. Preferably all over the perimeter leave the gap at least 1 cm.
  • If you mount a two-level ceiling or a design of multiple layers, then on the first layer of the screws are fixed at a distance of 60 cm apart from each other. On the top sheet of hardware placed in a step of 35 cm.

It is important to correctly form a crate, which often acts as a frame for mounting drywall. If the dimensions are not painted previously specified values, you can slightly reduce the distance between the elements to get the desired fixation quality.


Work with plasterboard is optimally simple, but requires compliance with some nuances. Especially often it concerns hardware.

To get high-quality and durable design, the basic rules should be followed:

  • Mounting fasteners should be placed only at right angles to the base. It concerns self-tapping and dowels. If the latest products are incorrectly installed, tighten the hardware to such a system will not work.
  • If you screwed the screw at an angle, you need to remove it and install it correctly. Specialists are not recommended to have self-tapping screws in the same hole. The best way to retreat from it aside by 5 cm.

  • All the fasteners need to be completely hiding in a drunk sheet of plasterboard. At the same time, they should not be deepened, since it is possible to destroy the material.
  • When installing sheets, ensure the absence of third-party objects between them and the frame. In another case, they may cause the deformation of the structure or the appearance of cracks.

Fasteners for plasterboard is the main element from which the service life of this material depends. Use only unique and high-quality hardware of proven brands that have proven themselves in the market only. Do not forget that you need to work extremely carefully, so as not to damage the plasterboard.
