Break tested 3 samples of stainless steel 10mm snap hook carabiners.
Manufactured in China
No rating
They cost me about NT$45, that's about $1.50 USD each.
The seller on Taobao advertised these as 316L stainless steel, however when I did two types of liquid detention tests, one showed it having some molybdenum content, and the other showed it not having the minimum 2% required to be 316. It's basically SS304. I messaged the seller and he said he'd contact the factory. Anyways, sometimes this is an issue when not buying direct from a factory, not all sellers know their products well, or double check information is correct/accurate. I'm not stating there is anything malicious here, it's just sometimes there's a problem in the sales aspect, and some North American shops are not exempt from this happening too.

As in my last video, I'd personally feel fine lowering off of two of these unrated 10mm stainless steel carabiners. And if I had the ones rated to 30kN that some manufacturers sell, then I'd be happy just with one.
I'm not affiliated with the manufacturer of this hardware, nor with the seller. I'm an independent climber & developer that is curious about all this hardware being made & used here in Asia.

DISCLAIMER: The information and "backyard science" testing shown in this video is not solid grounds to state a bolt, hanger, or hardware is safe and appropriate to install. It is the developer's responsibility to make the best judgment on up-to-date understanding and practices. Choosing to install and use uncertified climbing/rappelling hardware will raise additional concerns and questions: What is the quality of the raw materials and production method? Is QA(Quality Assurance) and QC(Quality Control) being conducted? What is the AQL (Acceptable Quality Level); meaning is proper testing of a sufficient sample amount being conducted? Does the product meet the requirements for possible certification? If it is certified, are up-to-date certifications provided? Does the manufacturer and/or retailer guarantee quality production? If a bad batch is discovered, will the manufacturer/retailer inform buyers for a product recall?
Developers and installers must also ask: Do I actually know who manufactures the product? Is the retailer I'm buying it from reputable? Is the bolt/hanger/hardware the appropriate choice and metal for the area, (e.g near saltwater)? Am I mixing dissimilar metals? Have I done any personal checking/inspection of the quality, strength, etc? Strong discretion must be exercised if deciding to use uncertified & unrated & untested: bolts, hangers, or hardware that was bought from a hardware-store that you intend to use for life-dependent situations (e.g. climbing, rappelling, rope access).
