Refers to the part between the connecting piece and the nut. A flat metal ring used to protect the surface of the connector from chafing by the nut and to disperse the pressure of the nut on the connector.Washer is divided into: flat washer - C level, large washers - A and C level, large washers - C

Original title: Bolt fastening SolutionsAt present, almost all bolts used in industry need to be controlled, which is the so-called torque control torque refers to the use of predetermined torque or predetermined torque and Angle, to carry out industrial fastening, in order to ensure enough clamping

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
