What Is a Connecting Link? US vs European Type
A connecting link joins two pieces of chain or a chain to a fitting. It looks like a small chain link with a removable pin or screw, which makes it easier to open and inspect than a welded link. This guide explains connecting links and how US and European types differ.
What Is a Connecting Link?
A connecting link is a chain link with one side that opens, usually by a pin or screw. It lets you join chain quickly and take the connection apart when needed. It is not the same as a cold shut, which is closed permanently.
US Type vs European Type
US type connecting link: a simple pin-and-cotter or screw closure, common in US chain systems.
European type connecting link: a different profile and closure, common in European chain systems.
Always match the link type, size and grade to the chain it joins.
How to Choose a Connecting Link
Match the link size to the chain link size and grade.
Choose the closure that suits how often you need to open it.
Confirm the WLL for lifting use.
Choose galvanized or stainless steel for outdoor and marine use.
Connecting Link vs Cold Shut
A connecting link can be opened and reused, while a cold shut is closed permanently. Use a connecting link where the joint may need to be inspected or changed.
