one of my neighbors brought an old power steering pump over to the shop today and ask me if I had the correct allen key to remove a set screw that he needed to remove!
the old part was covered in old dirt/grease and after trying a few allen keys that didn,t fit I grabbed a can of brake cleaner spray and cleaned and degreased the area.
I grabbed my lighted magnifying glass we use mostly for reading spark plugs and found I was dealing with a ROLL PIN which was about 3/32" in diam. so a drift punch was required to push it out! obviously no allen key would be of any use!

I could easily see where the confusion was due to the dirt and poor lighting
