The Dark Soul chain tools are made out of 7075. I have never seen the threads wear or strip out. I have seen the pushing pins fail, the screws get lost, and the groove where it pushes the pin through wear and deform. The dark soul tool does use dowel pins for the pusher screw and roll pins for the chain indexing.
