American standard chains are covered by ISO 606, ANSI B29.1 and DIN 8188 standards. The pitch sizes covered by this standard are 1/4 to 3 inch. American standard chains have a smaller pin diameter than the European standard equivalent. Wear resistance is therefore reduced when compared with the European standard chains. One exception is the 5/8 inch pitch, as in this case the pin and bushing diameters are larger than the European equivalent.
