To shackle or Quick Link?

Bang on the Mark Scotty.... and Never use a screw type link. The threads
strip in a hurry with very little force and then the entire unit straightens
out! I speak from experience here!

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

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

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

No, just a note, quite possibly a B-flat, one of my favorite notes.

Then you don't know how to properly use a micrometer.

WTF?
You trying to inject a serious note into this discussion?

2/16" that anything like 1/8" ?

Exactly the same. very good ozone. You didn't cheat and ask Jax, did
you?

I did, but he told me that 1 + 1 = 3 and that 1/16 should really be
1/17 because when you measure 1/16 the jaws of the micrometer are
never square and have a very small gap so the actually read a little
larger than actual.

are

No...I think 10'000 lbs of Beneteau with a pinch of Donal is a recipe for
