Update: contacted Irontrail about the super stakes having a crack and was willing to provide pics. Luke at Irontrail asked how many, I told him 8 out of the same dozen stakes. I had a tracking number for a new dozen in 15 mins.
Shout out to customer service not seen much anymore.
If the super stakes continue to crack, stainless fender washer anchors are cheap and I've never had one fail or pull out in 25 or so years in Pettis, Benton, Saline and Johnson counties. A J-hook and a few cents for a fender washer. Easie-Peasie.
All that I use on cable-restraints and dog proofs.
