In addition to the 200 feet of new galvanized anchor chain I also ordered two special shackles from 1st Chain supply. Normally, the weak link (no pun intended) in the anchor system is the shackles used to connect the chain to various thimbles and swivels. The problem is the shackles that one finds in the Marine store that fit inside the chain links have working loads less than the chain they connect to. The ones that are as strong as the chain have pins that are two big to fit inside the chain links.
There are two solutions to this problem. You can order the chain with oversize links at each end. but, order lead times are much longer (four to six weeks). The other solution is to use special alloy shackles that are as strong or stronger as the chain links they connect to. That is what I did. 1st Chain Supply has these alloy shackles available on their website they are in stock and I was able to order them when I ordered the chain. As I usually do before I connected them to the chain I coated the threads with Tef Gel to makes sure I will be able to take them off when I want to in the future.

You're not worries about corrosion between dissimilar metals? Or are these alloys galvanically similar to the chain?
I'm assuming the alloys are galvanically or at least similar to the chain. But, you make a good point and is something I will to keep an eye on.
