What is the difference between a carabiner and a snap hook?

Carabiners and snap hooks are both types of hardware used for connecting items, but they have distinct differences:

Carabiners and snap hooks are both types of hardware used for connecting items, but they have distinct differences:

Shape and Design: Carabiners typically have a more elongated shape with a spring-loaded gate that opens to allow items to be attached or detached. Snap hooks, on the other hand, have a wider, more rounded shape with a hinged gate or latch mechanism for opening and closing.

Intended Use: Carabiners are commonly used in climbing and mountaineering activities where strength and security are paramount. They're designed to withstand high loads and are often rated for specific weight capacities. Snap hooks, on the other hand, are more versatile and used in a variety of applications such as rigging, boating, and securing loads. They may not always be rated for climbing or high-load applications.

Gate Mechanism: Carabiners typically have a spring-loaded gate that automatically closes when released, providing added security. Snap hooks may have various types of gate mechanisms, including hinged gates, screw gates, or twist-lock mechanisms, depending on the specific design and intended use.

Strength and Load Capacity: Carabiners are engineered to withstand significant loads and are often tested and rated for specific weight capacities. Snap hooks may vary in strength and load capacity depending on their design and intended application, but they may not always be as robust as carabiners.

In summary, while both carabiners and snap hooks serve similar purposes of connecting items, they differ in shape, design, intended use, gate mechanism, and strength, with carabiners being more specialized for high-load applications like climbing and snap hooks being more versatile for various everyday tasks.
