Yes, socket*less* cap screws. As in no hole to insert a hex key, but other wise
the same shape and height as the head on a socket head cap screw. Roughly 5/16"
to 3/8" X short, standard or metric, course or fine thread, grade, material
unimportant. Does have to be metal... Thought about ordering shoulder bolts and
cutting the head off. May end up going this route but looking for a less
expensive and labor intensive solution since I may need as many as 50.

Could possibly live with an acorn head if it lacked wrench flats, but prefer
the cylindrical over bullet shape.
Another poster mentioned breakaway nuts but you can get bolts in this
style also. I used a couple for a job years ago but can't remember what
or why now. The bolts were used to hold the ignition barrel and steering
column lock on a European Ford application and were IIRC 8mm and maybe
30mm long but it was a while ago. Got them from stock at the local Ford
dealer parts department so a good place to start as I would guess the
same might be used in the US as well if that's where you are.
