I did the numbers pretty quick
In Response To: 304 stainless?? ()

316 stainless is mor likekly, you're right. Even so, the yield strength is somewhere around 42,000 psi for bar stockdepending on the condition. I'm sure you are also right that the anchor rode never gets to 90 deg but it is the sine of the angle so at 60 deg the lateral load would be 87%. I'm typing on my Ipod so I can't update my calculation sheet but even with these considerations (and given my very crude guesses at dimensions) the strength of the fitting is still only about 30% of the strength of the chain and I didn't even consider the strength of the weld. I'd want to make sure the fitting is not the weak point.
