Peculiarities

Screws on wood Quite often can be confused with such species of fasteners. The reason is that they look like this way, so it is not always possible to distinguish at first glance what exactly before you. However, with a detailed inspection, a significant difference becomes noticeable, and this is the main criterion when choosing a screw.

  • The head has a rounded shape, whereas other fixtures for fasteners it is semi-alone;
  • The head has a hexagon thread so that it can be conveniently wrapped using a wrench, and the diameter of the bolt itself is somewhat larger than the diameter of the screw;

If we talk about varieties, then screws are divided into several species, among which the most popular are the following:

  • construction, one of the most durable, which is intended to connect certain structures to be interconnected, is able to withstand quite large pressure;
  • Bilateral, which is designed to more in order to maintain the design, which is attached with one of the sides, while the other side often keeps into one or another surface;
  • Self-self-tapping screw, which is a combination of a classic screw and self-pressing, and the best qualities of the same product for fasteners are combined in this design;
  • long, which is intended to fix this or another device or construction of a large mass, or having a thick and long surface;
  • with pressshaba, often acute screw, made from zinc, is great for consolidating particularly durable surfaces;
  • black, manufactured mainly from carbon steel, so that this type of fastener is one of the most durable, it is used to fasten the gypsum fiber sheets, as well as for wood or drywall;
  • For fastening wooden lags, which have a tendency to cluster condensate, so they need strong fixing, and the screws of this type are perfectly suitable for such a job;
  • For balossine, it is preferably made by double-sided, from steel or iron, it can be used not only for its intended purpose, but also to fix various kinds of wood;
  • galvanized, such screws are covered with a layer of zinc, which increases strength indicators, as well as capable of withstanding large and heavy designs.

On the shape of the head

Screws also differ in Head shape.Among the most famous should be called the following:

  • with a secret head, when the head itself does not strongly drank, and a little concave inside the screw;
  • with a semicircular head, when the semi-bodied devices are visible;
  • with a semiplot head;
  • with hex head;
  • with a square head;
  • with internal hexagon.

Specially under the hexagon need to choose and tools, With the help of which you will work with similar types of fasteners. It is also necessary to take into account such a classification, since:

  • The first two types are intended for fixing the fittings;
  • Schupo with a semi-footed hat perfectly suitable if you want to work with accessories, which has extended holes;
  • On the hats is also marked which screwdriver will be the most suitable for working with this type of fastener, so if a straight hole on the hat, then it is better to use an exceptionally flat screwdriver.

In color and material

From this position, the screws differ as follows:

  • galvanized, which are designed for wood work and are presented on store shelves mainly in gold and silver shades;
  • Black phosphatated, which are created from special oxide steel, have a cruciform slot, mainly used for more rough work;
  • yellow-fashioned who have the same appointment and look as well as galvanized.

On the length of thread

From the point of view of thread, the screws differ in each other as follows:

  • Complete thread, under which the passage of the thread from the sharp end and to the outer border, sometimes it takes even to the hat itself;
  • incomplete thread that does not reach the hats, and ends at a distance of a few millimeters from her.

Other types

Classification not only includes a thread type, material or color. Screws also differ in other properties, among which they call:

  • A mirror screw, which differs from the classic fact that a cap of a semicircular or flat format is put on it;
  • double, which can be screwed into a one or another surface on both sides, is considered a universal fastener;
  • key, which is intended to fasten two parts with each other as hard as possible;
  • Cereal shuffle, which is quite commonly used by the tree, initially it was intended exclusively for conducting sanitary work, but later began to be used widely for different works with wooden surfaces;
  • Screw for tin, which is used not only for woodwork, but also to fasten several tin parts, it also easily bonds with a metal and plastic surface.

Currently there is another type of wood screw – Anchor, which is predominantly used for mramor’s work, as well as another type of natural or artificial stone.

However, it is often that such a screw is used to secure wooden products.

Tips for choosing

To choose the screw to work for a specific work, you must take into account several factors.

Mounting

Installation consists of two stages: calculation and technology. At the first stage, you need to determine how much screws will need in work, and on the second – exactly how to fix the design. It is necessary to take into account the mass of features, including what a hole needs to be made, as it will be necessary to secure what you have thought, how to fix – screw without a screwdriver or in this case it is rational to tighten the screwdriver.

It is also important to consider whether you are going to install floors or ceilings / walls.

Calculation

To produce Calculation of the number of screws, It is enough to find a special calculator on the network, which will help to find an accurate digit. To do this, enter the following data in the field:

  • type of screw (or any other fastener);
  • the length and width of the materials and surfaces that will need to be copped.

It can also be done independently with certain tables that are printed in specialized literature.

Technology

Installation technology occurs in several stages.

  1. Before screwing the screw, make markup, then do a small hole.
  2. Used screwdriver must match the thread on the screw screw.
  3. Next, turn the screws with the help of pre-drilling or without it.
  4. If the parts have a small hole, then it is necessary to make a pre-end-to-end hole with a drill that will be slightly labeled circle.
  5. If the details, on the contrary, have a greater thickness, it will be necessary to do a deaf hole with a size of a little less than the diameter of the screw.
  6. If you work with plywood or other thin wood, then you need to do the hole on your own hands. However, if the tree is tight enough, then you will need to take advantage of the drill.

Thus, screws for wood work differ not only by classification, but also by type of use.

It is necessary to take into account a lot of factors that will help you choose exactly the type of screws, which is suitable for your work, as well as finding technology, thanks to which the result of the work will be the most effective.
