National Hardware N240-374 Cold Shut Connecting Link, Zinc, 7/16 In.

A cold shut connecting link is a quick, tool-free solution for joining or repairing chain without welding or soldering. The National Hardware N240-374 is a zinc-plated steel link designed to restore chain functionality on the spot, making it ideal for outdoor equipment, fencing, securing loads, and industrial applications where a fast temporary repair is needed.

The cold-shut design locks securely once closed and cannot be reopened, creating a tamper-proof connection that holds safely for the duration of its use. By selecting a link one size larger than your existing chain, you ensure a snug fit that prevents slippage. This approach allows you to restore chain operation immediately while you source a permanent replacement, adding valuable flexibility to maintenance and repair work.
