When making an important decision to level the ceiling or wall with plasterboard, you should study all the subtleties of the work. One of the important points is the choice of self-tapping screws for profiles, for drywall. They have distinctive differences in technical characteristics as well as in functionality. Screws for drywall and profiles are sold in the construction market, in supermarkets. But, how to find out What screws are needed for fixing gypsum boards.
Varieties of self-tapping screws
All fasteners used in drywall construction are conventionally divided into 2 large groups:
Screws for profiles with and without drill.
Plasterboard screws are ordinary black.
The importance lies in the fact that - improperly selected self-tapping screws will create flimsy of the entire drywall structure. This will lead to early deformation.
Do not use self-tapping screws with a drill for fastening sheets of gypsum plasterboard. Using a screwdriver, ordinary black screws with a fine thread are perfectly wrapped in a profile.
To determine how many screws you need for purchase, use the calculator.
Self-tapping screws for connecting profiles and hangers
Let's figure out what screws are needed for a profile? Metal screws are divided into 2 types. Each is different in its technical capabilities and is designed to perform specific functions.
It should be noted here that it is possible to use self-tapping screws with or without a drill. The choice will depend on the quality of the profiles. It is better to hold the screws without a drill, but it is hard to screw them through two profiles, and for fastening the suspensions, that's it.
Screw with press washer
Among the masters there are such names of screws as "seeds", "bugs". They are small in size, are used to fix profiles to each other and are the most popular.
GKL self-tapping screw is covered with either galvanized or oxidized coating. Despite the different tips, the functionality of the fasteners is the same. In order to mount these screws, preliminary preparation is not required. They are easily mounted using a screwdriver or drill. The thin tip quickly makes a hole and by slight pressure on the screw it is firmly fixed in the profile.
Use a profile cutter to save screws and fast installation.
With its help, such self-tapping screws are used to firmly fix the profile to the crate or fix metal suspensions. It is allowed to work with a screw without preliminary drilling. A thin tip pierces the base of the material, and the caps tightly fix the screwed elements. The most popular sizes of self-tapping screws for fixing the structure and ordinary profiles with a length of 13-16mm.
Phosphated cone screws
Distinctive features of the head:
- If the tool jumps off the head of the screw, it is impossible to get hurt - it is rounded;
- It is convenient to press the self-tapping screw during installation with a screwdriver or screwdriver;
- With such cooking, in some cases it is possible to use a washer, a gasket;
- The cylindrical shape guarantees a secure fit.
Dowel nails for fixing the profile to concrete walls, ceilings
Fasteners designed for fastening the profile to a brick, concrete wall. Special self-tapping screws with a screw thread are used, complete with a dowel. The threaded screws are made of strong steel and are coated with agents that protect the metal from corrosion. There is a cross-shaped pattern on the head of the impact screw, which allows mounting (dismantling) the fasteners. The dowel has a spacer part that fixes the element in the wall (ceiling) when screwing a self-tapping screw there. The safety part of the dowel prevents the expansion part from triggering prematurely during installation. Using dowel nails allows you to speed up installation. The hole is drilled with a perforator, (with an M6 drill) a dowel is driven straight through the profile.
Self-tapping screws with dowels for concrete surfaces are produced in 2 types: countersunk head, mushroom shape. The mushroom head has an enlarged collar, which makes it possible to increase the area of the attached elements. During installation, the countersunk head completely fits into the material and does not stick out on the surface. This makes it possible to carry out additional work.
In the construction market, self-tapping screws for attaching a profile to a concrete (brick) surface are offered packed in packs.
|Impact screw 6 * 40 mushroom head||100, 200|
|Impact screw 6 * 60 mushroom head||100|
|Impact screw 6 * 60 countersunk head||100|
|Impact screw 6 * 80 countersunk head||100|
|Impact screw 8 * 60 countersunk head||100|
|Impact screw 8 * 80 countersunk head||50|
|Impact screw 8 * 100 countersunk head||50|
|Impact screw 8 * 120 countersunk head||50|
For a concrete wall, use dowels 6 * 40. This type of fastener firmly fixes the guide profiles to the base, on which the heavy load of the entire metal frame falls.
Self-tapping screws for fastening the profile to the tree
The screws are distinctive in length and pitch. Self-tapping screws with a length of 25 mm are used to fasten the profile to the tree. These screws are divided into 2 types: phosphated - black and universal yellow. Both types of screws have a countersunk head with a cross pattern for correct mounting of fasteners. And also the thread pitch is rare.
To mount the screw, there is no need to make additional holes with a drill. They easily pierce the surface and enter the base, while there is a strong fixation.
In the case of fixing drywall to a wooden crate, special wood screws should be used. These screws have a wide thread, which gives ease of tightening and fixing strength. The sizes of the screws used are different. But, the softer the wood, the longer the screw should be.
On sale screws can be in packs and loose. To calculate for one guide profile with a length of 3 meters, you will need to mount about 20 pcs of self-tapping screws with this calculation of the distance after 15-20 cm.
Self-tapping screws for fixing drywall
Consider what screws are needed for drywall. They are different in appearance, size, color.
Plasterboard sheets are attached to the created metal, wooden frame, as well as directly to the rough base. It can be concrete, brick, wood. There are dedicated fasteners for each individual mount. Self-tapping screws for drywall are made of durable steel with treatment against corrosion and oxidation.
A drywall sheet, in most cases, is attached to the created frame of metal profiles. The fasteners are driven into the sheet with a slight immersion so that the surface remains flat and smooth.
For this process, self-tapping screws for gypsum boards with a fine thread are used. The tip of the screw is sharp for good penetration into the metal. Self-tapping screws for drywall whose sizes start from 16mm. It is used depending on the thickness of the plasterboard sheet, as well as its quantity.
Basically, self-tapping screws with dimensions 3.5 * 25mm are used to fix one sheet of drywall. If you need to fix the second layer of drywall, then you need 3.5 * 35mm screws, packed in 1000 pieces. in 1 package.
The head of the drywall screw is designed in such a way that when it is fixed, the top layer of the cardboard remains intact, while the screw goes "flush". For screwing in, an electric or cordless screwdriver with a tightening force control is used. Plasterboard screws are manufactured to exacting quality standards and to specified dimensions.
The right choice when buying
Self-tapping cover. In addition to the basic material from which the screw is made, it is covered with a shell.
- Phosphated coating - black. Fasteners are used in rooms with high humidity.
- The oxidized coating is black. A protective film is applied and used in a room with normal humidity levels.
- Galvanized coating - indoor, outdoor use.
And also self-tapping screws have differences in the shape of the head, thread, tip.
Correctly choose a regular cross-shaped PH spitz for the bat.
When choosing self-tapping screws for gypsum boards, you should pay attention to the size, weight. All elements should have straight heads and cross-shaped recesses have clear edges.
