An integrally forged link for an endless track comprising: a link lower part having a bottom surface which provides a track shoe attaching plane; a window area above the link lower part, wherein there are two window areas and a strut therebetween in said integrally forged link, and two bolt through-holes each extending from the track shoe attaching plane towards a respective one of the window areas and penetrating to a lower periphery of the respective window area; each of the bolt through-holes being provided with a female thread, whereby a track shoe connecting bolt is capable of being inserted and engaged therein; reinforcing parts in a region which is located under the lower periphery of the window areas and which is located above the link lower part, so that said reinforcing parts prevent stress concentrations in said integrally forged link and in which region stress concentrations would be generated in the absence of the reinforcing parts; and an extended part of each said bolt through-hole is located in the respective reinforcing part, said extended part being provided with said female thread.
