Knuckle bolt

The main function of joint bolts is to connect and fix various mechanical equipment and structural parts, such as 

Bridges, buildings, mining equipment, etc. Because the joint bolt can be freely retractable, it can adapt to the deformation

 and stress of the structural parts, so as to ensure the firmness and stability of the connection.

Joint bolts are widely used in low temperature and high pressure valves, pressure pipelines, fluid engineering, oil drilling

 equipment, oil field equipment and other fields, often used in disconnecting occasions or tools, such as valve industry,

 folding bicycles, strollers and so on.

In addition, the threaded precision of the joint bolt is high, which can improve the overall workpiece quality as an accessory.
