I doubt it.
Anyway, in case you lower off somewhere in Europe, worth reading...

Never seen an aluminum biner from a hardware store on a climbing route or in a hardware store. I've seen steel ones, but they usually get tossed pretty quickly.
Pretty sure this is a euro thing. Interesting read though.

The take-aways are thus:
"- Every "hardware" carabiner sucks, to say the least, whether they are new, old, regardless of their shape, type, width and where they were bought in Italy. All, apart from one, open on average at circa 1200 daN (kg).
Every "climbing" carabiner, even the oldest, most used and worn, is better than the best new "hardware" carabiner. And even if really worn, they fail close to the stated breaking strength; this is almost twice as much as the average "hardware" carabiner.
Often the abseil carabiner on a single pitch sport climb (which therefore becomes the only anchor) is far and away the worst carabiner in a climber's gear kit. Often even failing, with a closed gate, at loads which are less than a "good" climbing carabiner with an open gate."
By 'hardware carabiner' they refer to those clips you'd use to maybe hang a hammock or something. Definitely available here, although I can't recall seeing any on anchors here.
A test of the varying grades of maillon rapide[quicklink would be of more interest. Seems like those are all over the map.
I'd use old carabiners myself but people f*ing steal them off anchors so I go with the quick links.

Hardware store quick links are completly bombproof. I will break your climbing rope any time you wish with a quick link. even the skimpy little 1/4in quicklinks are stronger than a climbing rope. they say they are only rated for 880 lbs but i tested them and was able to break 10.1mm climbing rope with a 1/4in quicklink in the system.

I do a fair bit of logging with retired climbing rope. I get all my firewood by gathering downed trees from the woods. you end up breaking a lot of rope this way and learning lots of cool stuff. the quick link test was specificaly to test quick links. The rope bearing surface was a standard climbng carabiner clipped to a 1/4" National quick link made in Malasia that was in turn clipped to the truck with a locking biner. I drop tested it with a pickup thruck and the rope broke @ the knott where it breaks in almost all of my tests.

I have used the same brand,the next size up ,with static 1inch webbing for years rigging framing jobs,etc.They are pretty tough.I have never tried to break em though.Good information.

I had zero intention of useing the 1/4 inchers for climbing aplication. I usually use the 5/16th and 3/8ths though lately I have been useing Climb tech quicklinks which seem to be of higher quality. Anyways I had a few 1/4" links hanging arround as I use them to fix plow chain. I just had the urge to see if the little ones would break climbing rope and they do. That test makes me super warm and fuzzy useing the 5/16th links.

working on a specific test for QL is complex.
i have seen very strong hardware store ql and some very weak.
a lot has to do to the tread (the screw thing). even some bought new in the same box were differend.
i have never seen an original Mailon Rapide even cut in half, to be weaker than listed.
some "problems" are now being known on the fixed draws (perma draws) where most ql are used.
my experience is that all UMBRANDED gear should not be used, or worse, left on a route.

No accountability means no quality control.
Maillon-Rapide is worth investing in for your quicklinks. Much cheaper than an ER visit.

I don't think it matters much, at least enough to justify the expense of using rated maillons as opposed to hardware store quicklinks if all you're doing is leaving them on fixed rappel stations.
Fixed quickdraws = maybe.

I will wager a $10,000.00 bet to anyone any time that I can and will BREAK YOUR DYNAMIC CLIMBING ROPE with a National hardwear store 3/8ths quick link. the test is really fcking easy. just tie a climbing rope to a 3/8ths in quick link and clip that to a pickup truck. tie the other end to a big assed tree. drop test the truck. the rope will break @ the knott every time unless it hits a sharp edge. If this test is not good enough for you then you are a hopelessly pathetic tech weinie.
Annother way of looking at it is if these things are so sketch where are all the dead bodys?

I don't know of many accidents involving Army surplus carabiners either but I certainly wouldn't economize that way. Beer is sold in all price ranges so suit yourself. I like Belgian ales and Rapide links...

Steve, I am useing Climb Tech links these days mostly because they are priced better than the local hardwear store. The bonus is they are better worksmanship than the Nationals and presumably intended for climbing aplications? I will not hessitate however to run down to my local hardwear store and grab some quick links if I have an anchor project, am out of stock and do not feel like waiting for mail order.
What part of I will completly DESTROY your climbing rope with a 3/8th link do you people not understand?
Heck, if I can BREAK your expensive European CE/UIAA tested rope with my POS Quick link does that not prove that your expensive, thouroughly tested rope is more of a POS than my quicklink?

I second that ^^^
My skinny ass couldn't generate 1/10th the load needed to break one of those things in a fall, and I don't generally rappel with my truck clipped to my harness so I think we're good here.
On another note, I completely trust a fresh 1/4in buttonhead in bomber granite as well... and a quicklink has got to have 10+ times the strenght of that.

Even with my truck i have never been able to get one of these things to fail. The Rope always breaks first.

Most of the manufacturing defect concerns that I have are with the smaller diameter quicklinks. Smaller rod size and rope wear makes a 1/4" unrated link a time bomb IMO. I like beefy anchors and install beefy anchors that will still be around long after I am gone.
Once you get into 3/8" diameter links then the safety margin increases to the point where they are pretty reliable. Beyond that it is really a question of preference.
I buy most of my gear at cost so the comparative price points are very reasonable. I buy a box and use them up and go get another one.

1/4" anything is a time bomb INMOP though I have broken climbing rope with 1/4 in link rated @ 880lbs I am assumeing that the working load of 880lbs is 1/3 of actual strength?

Interesting, because I remember the day when many fixed rappel anchors on this side of the Pond were straight from the hardware store. To me the best news was that even old "climbing" 'biners were much stronger than new "hardware store" ones.
As for 1/4" anythings, if nothing else, the relatively sharper edge would greatly diminish the breaking strength of anything passing over it.

Tradman can break ropes with trucks and malaysian links.
Check.

When I broke the rope with the 1/4incher i made certain that the rope bearing surface was a standard carabiner. the rope did not and never has broken over the edge of the connecting biners or quick links. It always breaks at the knot.
