Abstract
The ends of the metal pins of a chain of balanced design are carried in the aligned bores of the chain link sidebars. The links are of an engineering plastic and the ends of each pin are deliberately fitted differently in the one and the other bores of the two sidebars such that cyclic loading as in chain operation causes the pin to 'walk' in the direction of the other bore. Abutment means prevents movement of the pin in that direction and the pin is thereby self-securing but can be readily removed in the other direction when required.
