A screw is actually a type of fastener whose long and cylindrical body is completely or partially threaded and has a screw head in various shapes. The nut is also a piece that plays an auxiliary role and is often in the shape of a hexagon. These products are used to connect two parts of the same material or two parts of different materials. The classification of bolts and nuts is usually done based on appearance, material, size, type of application and other parameters. They are used in various industries. In order to be able to choose the right type of bolts and nuts, observe the following points before buying.
Important Tips on Types of Bolts
The higher the grade number, the higher the strength. For example, grade 5.6 is made of low carbon steel and has little resistance compared to grade 8.8.
Carbon steel is highly used in making all kinds of bolts and nuts such as grades 4.5, 5.6, 6.8, 8.8. The main factor in this type of steel is the amount of carbon. Carbon increases the heat treatment capability of steel. Phosphorus, sulfur, manganese are added to steel as needed to improve machining properties.
The number inserted on the bolt and nut indicates its strength. For example, the number 8.8 means that each square millimeter of the cross section of this screw can bear 80 kg or 800 newtons of force and can bear up to 80% of the final force without any deformation.
Where to Buy Bolt?
Due to the fact that various parameters play a role in determining the quality and strength of bolts and nuts, you should have complete knowledge and understanding of their types when purchasing these parts.
