In Hollow Pin Chain, the pin has a hole, allowing for the installation of various attachments. Usually, these chains are used for conveyors. 
The advantages of installing attachments into the hollow pin include the following:
1. The hollow pin is at the center of articulation and always keeps the pitch length. Regardless of whether the chain is straight or wrapping around the sprocket, the center distance of attachments is always the same. 
2. With a crossroad over two chains, the load from the attachments is distributed to both sides of plates equally. The chain can fully use its strength and not twist.
3. It is easy to change, maintain, and adjust attachments.
