Twist Link Coil Chain

Twist Link Coil Chain

Long pitch straight link or twist link, general utility chain made of carbon steel. Not to be used in overhead lifting.


Not to be used in overhead lifting applications.

Material – Carbon Chain
The selection of the base steel is left to the judgment of the individual chain manufacturer provided the steel meets the following criteria: Carbon, 0.35% max.; Phosphorous, 0.040% max.; and Sulfur, 0.050% max.

Working Load Limit (WLL)
The "Working Load Limit" (rated capacity) is the maximum load that shall be applied in direct tension to an undamaged straight length of chain.

Proof Test
The "Proof Test" (manufacturing test force) is a term designating the minimum tensile force which has been applied to a chain under a constantly increasing force in direct tension during the manufacturing process. These loads are manufacturing integrity tests and shall not be used as criteria for service or design purposes.

Minimum Breaking Force
The "Minimum Breaking Force" is the minimum force at which the chain during manufacture has been found by testing to break when a constantly increasing force is applied in direct tension. Breaking force values are not guarantees that all chain segments will endure these loads. This test is a manufacturer's attribute acceptance test and shall not be used as a criterion for service or design purposes.
