Heavy Duty Stainless Steel Thumb Screw Locking Carabiner Spring Snap Clip Link Hooks. 200-400lb Load. 6 Packs and 12 Packs

They are great and strong. Not just the junk attached to a trinket or plastic trash. I like the quality of these carabiners and would suggest them to anyone

Priced great...quality very good

This set of carabiners fit my need for use with wall tent tie downs

Exactly as expected, very strong and a good size for multi-purpose use. Good value.

I needed SS, and these fit the bill. Especially nice that they can be closed and secured until such time as they need to be opened for one reason or another. My only complaint is they are smaller than I anticipated. Still very useful.

I guess I didn’t realize what size I was ordering, but I was trying to get new clips for my home gym cable attachments. Ones that came were pretty small, I still chose to use them and they haven’t broke yet. I haven’t gotten them max on the weight though, so not sure how strong they will be, but they are good for what I’m using them for.

HIGHLY Recommended!The materials used for the construction is much more "Heavy Duty" than expected! I have not had a chance to put these clips to a test yet, but I am positive they will perform well beyond my needs/requirements.

First of all, it should be obvious that these are NOT rated for climbing or other uses where they may be subjected to sudden high impacts, but in case that's what you were thinking of using these for, don't. For static loads--even relatively heavy ones, these should do just fine. It says it is rated for "180kg (400lb)". While I haven't tested that at all, just judging by the feel of it my hand--the thickness and weight of the steel itself, and given that when the gate is fully closed, there is a good, snug fit, I fully believe that it could handle 400 LB without risking breaking.PROS* Heavy duty* The lock on the gate can, if you want it to, unscrew all the way off if you are holding the gate open and unscrewing it at the same time. This would be a very intentional thing to happen, so I'd call it more of a pro than a con since it gives you options.CONS>>> Given that this is not a climbing-class carabiner, these cons are pretty common and, in fact, many other biners in this class are much worse in these areas <<<* The gate itself has a little bit of play to it, which means one handed operation is sometimes just a bit harder as the gate may push to the side slightly and then slide off your thumb OR it may mean that the gate doesn't fully close without you giving it a slight bump to the side (which won't be a problem if you are locking the gate closed, anyway.* The spring for the gate is plenty strong, but there is a slight sticking point that is bad enough on some of them that makes them not close on their own until, again, you give them a slight bump in the right direction.OTHER THOUGHTS* The lock only screws onto the gate itself. There are no threads on the part the gate makes contact with on the top. This is not necessary, but it does (at least theoretically) add just a bit more strength to the closed (and locked) gate and thus to the biner as a whole.
