Cap screws from which kit?
And what i see is a manageable, non-catastrophic failure when subjected to loading far more than realistic worst case. They are rated for 12% elongation minimum meaning like a 1.5 in radius bend before breaking (and you probably slip off first, or the bending force drops).
Bending is a safety feature. Unless you are looking for some serious fall arrest (and there are better options) 3/8 gr 8 is fine.
I agree with you on the 3/8 from the hardware store bending being the better option and in all reality in normal use would prolly be no big deal.
The bolts in the middle are the ones that sheered off and snapped. They broke right at the threads. They broke flush with the tree. These were out of a kit I bought but they seem to be the bolts that are offered by treehopper and quick and quiet.. I just assumed they couldn’t handle that heavy of a load so started testing other bolts.
The 3/8 were all drilled same depth with same bit with stopper
