What is the bead?
Nuts are a type of metal fastener with a defined internal space. which are used to secure parts using screws or rods. There are different sizes and types of beads in the market; Each is designed with a specific purpose. Some nuts can be used without special tools, and some others may have special designs to prevent the screws from loosening. Therefore, it should be said that bolts and nuts complement each other. Anchor bolt, master bolt, chamber screw and other widely used screw models each require their own nuts to be tightened. For this reason, today we see different types of bolts and nuts with different applications and for use in different places. .
Most nuts are tightened by rotational force around the bolt, although some nuts may be compression. The method of fastening the nuts is not important, the nuts hold the components together by mechanical property: this mechanical property is from the friction of the bolts and nuts against each other, which is caused by the partial tension of the bolt due to the compression resistance of the joined parts. is formed, and a slight deformation of the elastic shape of the parts together occurs. Therefore, the beads can be used as a proof of fastening the parts to each other.
Application of beads
What is a screw?
The screw is actually a cylinder surrounded by spiral grooves. The design of the screw groove is different for cutting softer and harder materials, the grooves are often formed in the form of triangles, squares, trapezoids and semicircles on the side surface of the body. The most common use of screws is to hold objects and parts together. At the end of most of the screws there is a special and pointed part to make it easy to enter the part. Common tools for using screws are wrenches and screwdrivers, the head of this tool is usually larger than the body of the screw so that it can apply more force to the screw and drive it along the piece.
