Steel quick links are specifically designed to link chain to itself or other items, but allow quick changes if necessary. These zinc-plated steel, oval links center themselves quickly for impeccable chain balance and security. These links will never suffer the re-annealment problems of split key rings, quick release snaps, or other spring-based solutions. And with just a quick counter-torque with two screwdrivers, can be rendered almost impossible to open or close (for long-term security).
