Nitro™ ANSI Cottered Roller Chains
Cottered roller chain uses cotter pins on one side of the chain versus being staked "riveted" like standard roller chain. The main benefit of cottered chain is the ease of cutting down the roller chain, which is why most cotter pin chain is available in the larger ANSI chain sizes. No grinding of the pin head is needed! The cotters are manufactured from carbon steel for improved shear strength.
