Countersunk screw: use

The 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 fastening bay must be threaded. In the plane of the head is cut a cross-shaped slot for screwing.

Sometimes it is required to connect the parts in such a way that their surfaces do not have any protruding parts. In this case, a screw with a countersunk head is used: securely fastening two surfaces, outwardly it remains absolutely imperceptible. In the common people it is often called the screw "sweat". To mount this connector, use a Phillips screwdriver. After installation into the threaded hole, the screw is screwed into the right side.

This fastening is used in a wide range of industries: instrument making, mechanical engineering, shipbuilding, utilities and other areas. And in the manufacture of furniture screw with a countersunk head - just an indispensable element. With it, tables, sideboards, beds, cabinets and other interior items are aesthetically attractive and comfortable. Often such screws have different additions, for example, an internal hexagon, a sharpened end for self-cutting, 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. From the usual, it differs by the presence in the head of a hole of a special shape. For unscrewing and screwing into it a special hexagonal key is inserted. Such fasteners are stronger than simple ones, besides it lasts much longer. Slots of the usual screw with frequent unscrewing quickly become unusable, which never happens with a hexagonal groove.

A screw with a countersunk head does not spoil the appearance of things, and the screw with an internal hexagon is very reliable. Both types of fastening are very popular both in industry and at home. Combining these qualities, they produce screws simultaneously with a countersunk head and an internal hexagon. Using them, get very strong, and at the same time, inconspicuous connections.

GOST for bolts and screws prescribes the use of only special steel for their manufacture, because the quality of these elements is often directly related to the strength of very important compounds. For example, in the construction and engineering industries, the security, even the life of people, can depend on the reliability of such fastenings.

Screws and bolts can be made of brass, copper and even wood. Steel fasteners are produced both uncoated and with it. The latter is most often white zinc.

A screw with a countersunk head is very important, and sometimes even an indispensable element. At present, without the constructions made with its help, it is impossible to imagine practically any sphere of industry. No less often it is used in everyday life, allowing you to perform very strong, hidden and accurate connections.
