A 1/4" button head cap screw. All the tools are at home and I'm trying to write up a description for a friend. For the life of me I can't recall what size allen wrench to use with a 1/4" button head cap screw. As I recall it's 5/32" but it's been one of those days where coffee just isn't taking the edge off.

Yup, 5/32"

Now I'm trying to dust the cobwebs to figure out the trig for the distance across the points of a 5/32" hexagon.

.18042 is too short, I had to add at least five characters.
