The AS cover
ALL recommended/recognised applications & uses of Slings, Rigging, & Lifting Equipment, and these Ring Eyes/much of their use falls under the latter two of those three, and they are frequently directly involved in the use of Slings too. So yes, the part that applies is pretty much the entirety of the Aus Std
and it's US/European & other Country's equivalents!
But by using the ring eyes as tie-downs, you aren't loading along the axis of the threaded shaft - and for each degree you move away from that axis, there's a marked reduction in strength....
PLUS there's the shearing forces applied on a very small section of 'already weakened by threading' bolt,
AND the added leverage & therefore twisting forces applied on the 'somewhat less than massively strong' A-arm tubes, that small section of thread, & the bottom eye of the shock by how far ahead of all those the Ring Eye projects.
But you go right ahead & use them how you will - I've posted my 'word of caution'. :thumbup:
