What is the thread?

The term sub -process is used to describe a particular design or profile of the screw thread. Defining the characteristics of the buttress sub -processes are almost perpendicular leadership of the face or edges and strongly oblique end faces. This design allows the pad fiber to exert considerable strength in one direction of rotation and quickly tightened and relax with a minimum of friction and effort. The fibers of the backrest are most often used in the production of lead screws used in machines and as hydraulic seals for viscous liquids such as oil. When turning in a particular direction, the screw is tightened and this voltage is released when it turns in the opposite direction. The profile of this screw reflects this in the specific characteristics of the front and end surfaces of its individual fiber peaks. If some threaded, such as the IS screw, cuts over the entire length and view from the side, the thread profile will resemble the teeth of the saw with a number of equally located peaks and troughs. Parts of these peaks pointing from the head of the bolt are known as the front edges and those SMMidden to head, end edges.

A good fiber is characterized by the front edges that are almost perpendicular to the axis or the length of the screw and the end edges, which are quite sloping. Usually, the front edge of the fiber is tilted at an angles of 3 ° to 7 ° and the end edges at an angles ranging from 33 ° to 45 °. This means that the fiber profile below the thread looks more like a sequence of waves than V shapes that are seen on a conventional fastener such as a nut and screw. This unique fiber formula allows objects to be cut into the cheating fiber to develop a strong force in only one direction and rented with minimal efforts.

The type of fiber can be an ideal choice for use on the machine screws, such as those used to open and close benches where the tensioning power is needed in only one direction. This principle also makes the backrest with a good choice for useIts on the blocks of artillery weapons, where it is necessary to lock very strong lock to contain the rear force developed by the burning of the driving substance. The fiber design is also very suitable for use in viscous liquid seals, such as those that are considerably used in the pipeline of the oil field. The fibers powerful one -way parallel axis allows firmly sealed joints that can be quickly removed and tensioned and with a small effort.
