    The slot in the head of that shaft sure is a curiosity. In keeping with my (usually valid) hypothesis that engineers and manufacturers don’t add features to parts for no reason or at extra cost…  wonder how the slot got there? I have only two guesses… 1 –  there is some sort of key or tab on the shaft to engage in the hole to keep the shaft from spinning should the swage loosen? The slot allows rotational alignment at time of assembly. 2- the shaft is made from a hardware stock shoulder screw that came with the slot for “free” .

    Ideas ???
