Best probability is the screw thread will be metric.

If you have an identical shoulder screw from another driver, same engine, a photo would help, as per GRJ's comment.  Measurements of OA length, shoulder diameter/length would help, too.  If the screw head ends up recessed in a counterbore in the rod, the screw head diameter would also help.

BTW...Just another suggestion.  If you remove an identical screw to provide the above info for us, check to see if it's attractive to a magnet.  If so, and if the screw 'fell out' along the layout somewhere during operation, you might also try scanning the track with the magnet.  I did that once long ago in my HO days.  It's amazing what you'll find!...and hopefully that missing shoulder screw!!

Hang in there.

You'd be amazed what this car picks up on a trip around the layout.  The Neodymium magnet has a pull force of over 100 pounds, it's the K&J BY0X08-N52.

Everything but the axles and that coupler screw is non-magnetic, I use plastic wheels as the friction with the magnetic attraction stopped the metal wheels cold and it was just dragging them down the track.  When done, I just pick the magnet out of the car and all the stuff falls off the bottom of the car.

HOLY GAUSS!!, John!   Magnetraction move over!!!

It's a wonder you don't end up with a bazillion track spikes and floppy rails at the end of a pull!!

Tim Taylor (Home Improvement) would surely be proud of your design..."MORE POWER!!"...that's for sure!

Neodymium magnets...a whole new 'field of dreams' for the hobbyist!

Any concerns for trackside electronic devices when the gauss-mouse passes by?   (Apparently not...you'd be the guy to know!)

OTOH...gotta put this on my project list.   Getting too old to crawl around to the layout pop-up's to do a  manual magnet scan!

Awesome!
