The sole purpose of an 16B hollow pin connecting link is to join two sections of the hollow pin 16B roller chain and is also commonly referred to as a 16B hollow pin master link. Our premium DUROCHAIN 16BHP connecting link is a genuine tier one link made from the best quality carbon steel material, with unique hardened pins and shot-peened components for the maximum capacity possible. When it comes to a roller chain, we all know it's no better than its weakest link; that's why we expressed the same quality and artistry with our 16B hollow pin connecting link as we did in our chain.
