Abstract
This invention relates to an endless track having chain links which are connected by connectors as well as rod members extending through the connectors. A connection between the connectors and rods is provided by clamping contact surfaces on the rods and connectors in abutment with other, at least one of said contact surfaces comprising at least one depression arranged around the circumferential area of the bolt or connector contact surface, whereby a friction lock preventing the bolts from moving axially and/or rotating with respect to the connectors is achieved.
