National Mfg N240-341 Zinc Cold Shut 1/4 Inch 20 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N240-341 is a zinc cold shut designed for temporary chain link repair and chain coupling applications. Cold shuts are open-link fasteners that allow quick connection or repair of chain without tools. This unit is manufactured from zinc-coated steel, providing basic corrosion resistance for light-duty use. Each cold shut is sized at 1/4 inch and is intended as a single-use fastener — it must not be reused after closure. This package contains 20 pieces, bulk bagged for jobsite or shop use. Typical installers include maintenance technicians, riggers, and general tradespeople working with chain assemblies.

The N240-341 cold shut is suited for temporary repairs on 1/4 inch chain or as a coupling link to connect chain to attachments such as hooks, rings, or anchors. Per standard practice, install one size larger than the chain being repaired to ensure proper fit and load distribution. This product is intended for temporary, non-critical applications only and is not rated for overhead lifting or permanent load-bearing use. The 20-piece bulk bag suits service vans, maintenance kits, or light inventory stocking.

Installation Notes

Cold shuts are installed by hand or with light-duty pliers to close the open link around the chain. Always select one size larger than the chain to ensure the cold shut seats properly. This fastener is single-use only — once closed, it must not be opened and reused. This product is not intended for overhead lifting, permanent structural connections, or safety-critical load-bearing applications.
