Machine Straight Link Welded Steel Chain (NACM90)

Finish: Self Colored, Zinc Plated

Produced to the NACM standards

Do not use in overhead lifting applications

Machine Straight Link Welded Steel Chain (NACM90) is a type of chain that is commonly used in overhead lifting applications, as well as in general-purpose applications where moderate strength and durability are required.

The “welded” construction of the chain means that each link is fused together using a welding process rather than simply being interlocked. This provides additional strength and security, as there are no weak points where the links could come apart.
