Screws are widely used in electrical engineering, automobile manufacturing, mechanical equipment, construction and decoration, food and medical machinery, petrochemical industry, shipping equipment, coal mine machinery, aviation instrument manufacturing, transportation facilities, steel furniture and other fields, and are very important products in modern life.
1. The screw has been corroded, and the thread of the screw will fail due to insufficient hardness, so new screws need to be replaced.
2. The combination deformation of screw pulling and torsion is caused, especially the torsion deformation will be twisted and broken when the thread connection is made, so the shear strength of the material is greatly less than the tensile strength.
3. Although the screw is small, it can be used for a wide range of purposes, so that the assembly and installation of any equipment cannot be separated from each other. Therefore, the screw manufacturer reminds you that if you want to use the screw, you need to choose products with good quality to ensure normal operation.
4. Weak separation from base metal and poor bonding force will lead to thread failure, so it is necessary to check whether the connection is correct.
