Another anchor question: Why don't we use quick links rather than shackles to attach the rode to the anchor?

Seems to me that the same size quick link is about 20% stronger than it's shackle equivalent, and if you tighten the closure nut with a wrench there's
no way for it to work open. Even if you only tighten by hand and by some miracle (fish with fingers, crafty crabs?) it manages to work open, you still
won't lose connection so long as there is some tension on the rode.

20% stronger? Where did you get that from? I thought that a shackle was
stronger.

There are different grades of shackles.

Looked up several different manufactures, typical values for a 5/16" quick link are around 1700 lb., for a standard grade carbon steel, galvanized
shackle the number seems to be about 1500 lb.

I realize that you can get shackles in different grades, just as you can chain. How many of you go out and buy grade 70 transport chain to use on your
ground tackle? I'll bet most buy proof coil (grade 30), in which case the basic el cheapo shackle is going to be stronger than the chain anyway.

I was merely musing that IMNSHO, the quick link is less likely to work loose, unless of course you mouse your shackle with stainless steel wire, which
is a pain in the butt some days.

Why stainless? I mouse with galvanised wire, and change it when
it looks seedy. Tho' I suppose the fresh?water use stops that
being much of a chore.

Galvanized works just fine, it just happens that I have a bunch of stainless on hand from the MIG welder.

I carry stainless rigging wire, but I usually mouse with cable ties - you have
to check them, but they seem to last a season with no trouble and can be popped
off with a pliers.

I do, all the time. Have about 300' of it on the truck.

OH!

Not me, I just went out to the barn and cut a length of 3/8' G70.

All my shackles are moused w/SS wire.

DO NOT USE A QUICK LINK!!! Seriously! Never! They fail 100 % of the time at
light loading weights when compared to the chain..

More to the point. the shackle you can fit to the chain is weaker
than the chain. Buy your rated chain from an industrial sling mfg. and
have them put an oversize link at each end. (small extra charge). Now
you will be able to fit the proper sized and rated shackle.
