SkyletyMini Titanium Locking Clips D-Ring Locking Snap Keychain Keyring Screw Lock Buckle for Outdoor Indoor Dog Tags Use, Lightweight and Sturdy

These worked great for keeping zippers closed on suitcase for travel. Good design and very sturdy metal clips with easy to use screw-type closure.

Amazing quality, threads precision, locking bushing, titanium, can't be beat high strength lightweight the best.

These are great size, strong & light!

The issue is going to be: relatively hard metal (titanium) vs. seemingly relatively soft metal (brass closure); in a fight, the brass loses. So I'm concerned that tightening the closure enough to make sure it's _really_ closed will eventually strip it. We'll see. Meantime, these seem pretty fair.

Not for climbing! I like the screw gate feature because it can't pop open.

I don’t know why, but companies sell kitchen items with rings that rust. These don’t and they are perfect!

OK, light weight. But I don’t use these for the intended purpose because they are not strong enough. . With enough force - which is not too much and happened fairly often - the body will pull out of the screw gate.So, OK for light loads only.

I have long nails and have a terrible time getting the regular circular key rings open to slide my keys on. These are easy, they're pretty, and they're small, but still large enough to hold lotsa keys.
