Tighten bolts and nuts according to the following standards. There is a lot of work to tighten threads when assembling mechanical parts. In fastening operations, tools play an important role, through the correct use of the most suitable tool for the operation, can carry out the correct operation, wh

In this section, a bolt axial force detection system based on ultrasonic surface waves is established. The transmitted signal energy of the surface waves can be used to detect the bolt axial force, and the attenuation of the bolt axial force can be monitored online by using the surface wave energy d

The stainless steel bolt encountered water condensing in the air. Pollution means they contain a lot of sulfide or carbon monoxide. When they come into contact with water, they form sulfuric acid and hydroxide, which chemically corrode stainless steel bolts. Stainless steel bolts rust because the pr

When we use stainless steel screws, nuts and bolts, we often encounter the problem of locking, so what is the cause? How to solve this problem? The deflection Angle of thread matching and the soft characteristic of stainless steel are easy to cause the matching of locking screw and nut.With their re
