I agree with the posts about the tool being designed to be more or less idiot proof. I have one. But the first Hollowtech crank I installed was before I got the tool. I just took a small/fine-bladed needle nose pliers and spread it against the fastener to tighten it. I read the installation instructions so I understood it should be about finger tight and did so.
