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

01 Replace thin with thickFor important connecting parts on the machine, such as drive shaft and flying shaft, the bolts are usually threaded with fine teeth. When missing parts during maintenance, someone replaced them with coarse bolts. Due to the large inner diameter, small pitch and external Ang
