Smart shopper! Very useful, can't live without them.

 Not really smart.  It was an impulse buy at a local thrift store.  It
looked new and the price was right (about $10).  I don't really need
it as I have other calipers and micrometers:

Meanwhile never say never. Or always:

 Nice.  However, I don't need such hardware very often.  Instead, I
just drive to the local hardware store and buy as needed:

They don't have everything, but between their inventory and my
disorganized collection of fasteners that I've accumulated over the
year, the arrangement works well.  If I need to order fasteners on
eBay, I usually order 100 at a time.

Those grub screws are actually on topic.
Mr Kunich has observed that there are three of them on the current upscale Shimano 2x12 front changers.  One sets the low gear stop. A second sets high gear but is designed such that clockwise expands, anticlockwise restricts. That's the only case for any derailleur ever AFAIK.  The third screw is effectively a cable tensioner in that it rocks the entire plate supporting the anchor assembly.
