What term is used for fittings that connect various rigging hardware components?

The term used for fittings that connect various rigging hardware components is "shackles." Shackles play a crucial role in rigging applications as they provide a secure connection point for slings, chains, and other lifting equipment. They come in various shapes and sizes and are designed to handle different loads, making them versatile components in the rigging process.

Shackles can be either screw-pin, bolt-type, or safety-type, each suitable for different applications based on load requirements and safety considerations. Their ability to be easily connected and disconnected while providing a strong, reliable link makes them essential in rigging operations, especially when assembling and disassembling systems for lifting loads.

The other terms do have specific uses in rigging but do not primarily denote fittings that connect rigging hardware components in the same manner as shackles do. Bolts are typically used for fastening materials together rather than connecting items in a rigging context. Links may refer to various types of connections, but they are often part of chains rather than standalone connectors. Rings can be used for connections, but they usually serve different specific functions and don't carry the same general application as shackles for connecting multiple rigging components.
