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

These are EXCELLENT for key ring/key chains. I worry about the screw closure - unscrewing - but that hasn't happened once and I handle my keys a lot through the day. The screw closure has enough thred for the closure to get a good tight grip. The d-rings are light, large enough to hang keys from, and are small enough so that it is part of the ring, and not an addition that seems over-kill like some spring loaded key rings may be. I like them, and bought a bunch, for the price of just 1 other type of d-ring.

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.

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.

Been using these as keyrings to attach and detach keys quickly. Detaching the house key from the car key set about 5 days a week since purchasing; durable, secure, and easier than a keyring.

These are sturdy and come in handy for lots of temporary tool hanging solutions.

These are great size, strong & light!

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

I use these to secure luggage zippers closed.

Leicht und nützlich für eine Vielzahl von Verwendungen.
