The set you have is for a Stage One I think?? I also had a set like that & used them for a few years but the middle length should really be longer like the centre ones. There should really be 2 sizes only, long & short, that would be a better way to explain. I found that the middle length ones are a tad short if you want to put them all the way into the block like the rest. Almost too short for washers or you have to undo a couple threads so they stick up. Never liked that & found out later they are for I believe a Stage One (please correct me if wrong) & not a stocker. I have them in a pile & wont use them anymore. Good for spare washers or nuts if need be!
