Hypothetically... if I went to Home Depot and bought, say, 10 non-stainless 5/16" quicklinks (these being what I normally leave at backcountry raps), how many of them do you think would fail at less than 1000 pounds?

I'd say none of them.

How about 2000 pounds? The working load limit is given as 1760 lb, and there's some margin (3:1? Maybe 5:1) built in, right? So I'd guess they'd all be good.

I'd guess they'd all be good to 3000 lbs.

So tell me why the report in the OP should alarm me. Because it's "real data"? Compared to my conjecture? Is it because you (note - I'm not responding to anyone specifically) think there's no quality control if it's not "climbing rated"? And that therefore there may be hidden defects that would cause 1 in 100, or maybe 1 in 1000 to explode under body weight? Shall we chip in and buy 1000 and have them tested? Whoever's wrong gets to reimburse the costs.
