SHONAN 3 Inch Stainless Steel Chain Quick Links- 4 Pack 5/16” Large Locking Carabiners Heavy Duty Chain Connector, 1535 Lbs Capacity

One link locked up after unscrewing it all the way. Two other links locked up after screwing them shut all the way. A wrench wouldnt work. Tried WD-40 on them, but that didnt work. Had to use a bolt cutter on the two that locked while screwed shut. If we hadnt had a bolt cutter, it wouldve meant our pet being stuck in a cage, because we wanted to use the links as extra security while we were out of the house.

This is a great product and very under rated. This connector will pull a big load.

good for removing my engine chevy sbc

I havent used them yet, but they are well-made, I have ordered before, and they have held up well.

Worked Great

I use these to connect a dog leash to a harness/collar and this is far more secure than the connectors that come with most dog leashes. I have had other fasteners fail. These are very reliable and secure.

These are best I have found - nice packaging - really high quality with no manufacturing flaws

great fit

Very low quality.

I did not need 5, just 3 for my boat. But quick links are things you do not know what you can use them for until you have them. They will not be in my tool box for long. And if I need more I would order them again.
