Even more dumb now...
A) I thought I was trying to buy some of those cool T15/slot head screws
B) while I was posting the original thread, I was looking at the six black button head Phillips long screws, And six short silver Phillips flat head screws rattling around in my 1400 systainer thinking to myself, “I wonder how these got in here”
2+2= the table widened comes with replacement standard base screws with Phillips heads, and the longer Phillips head extended screws
Face, meet palm...
