Industry produces a huge number of types of fasteners designed for different purposes. These are nails, bolts, screws, anchors, screws. It is the latter that will be discussed. A screw is a connecting element with a cone-shaped head and a threaded rod along the entire length. It is used to connect various parts (wooden, metal, plastic, etc.). The mounting socket must be threaded. A cross slot is cut into the plane of the head for screwing in.
Sometimes it is required to connect parts in such a way that their surfaces do not have any protruding parts. In this case, a countersunk head screw is used: securely fastening two surfaces, it remains completely invisible from the outside. In the common people, it is often called the “sweat” screw. A Phillips screwdriver is used to mount this connector. After installation in a threaded hole, the screw is tightened to the right side.
This mount is used in various industries: instrument making, mechanical engineering, shipbuilding, housing and communal services and othersareas. And in the manufacture of furniture, a countersunk screw is simply an indispensable element. With it, tables, sideboards, beds, cabinets and other interior items are aesthetically attractive and comfortable. Often these screws have different additions, for example, an internal hexagon, a pointed end for self-tapping, etc. This greatly expands the scope of their application.
The hexagon socket screw is useful in cases where it is necessary to periodically connect and disconnect parts. It differs from the usual one by the presence of a special-shaped hole in the head. For unscrewing and screwing, a special hex key is inserted into it. Such fasteners are stronger than simple fasteners, and also last much longer. The slots of a conventional screw quickly become unusable when often unscrewed, which never happens with a hex groove.
The countersunk screw does not spoil the appearance of things, and the socket screw is very reliable. Both types of fastening are very popular both in industry and in everyday life. By combining these qualities, screws are produced simultaneously with a countersunk head and an internal hexagon. Using them, they get very strong, and at the same time inconspicuous connections.
GOST for bolts and screws prescribes to use only special grades of steel for their manufacture, because the quality of these elements is often directly related to the strength of very important joints. For example, in construction and mechanical engineering, safety may depend on the reliability of such fasteners,even people's lives.
Screws and bolts can be made from brass, copper and even wood. Steel fasteners are available both without coating and with it. As the latter, white zinc is most often used.
The countersunk screw is a very important, and sometimes simply irreplaceable element. At present, without structures made with its help, it is impossible to imagine almost any industry. It is no less often used in everyday life, allowing you to make very strong, hidden and neat connections.
