This is for a Weaver C-1, Pennsylvania, 0-8-0, Masonic Switcher. This a screw for the connecting rods (shoulder screw).

Still looking for this screw. Any suggestions appreciated
I'd start by trying to get exact measurements, a picture, and also determine the exact thread pitch and diameter. There are tons of different rod screws, so guessing for a locomotive we don't have is pretty poor odds.
First find out what screw threads into the hole, this way you know the size and thread. chances are you won't find the correct shoulder screw, so use a piece of tubing. I made a few shoulder screws this way, even using multiple size tubing to get the correct diameter shoulder.
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.

What a great tool. This should be a "Must Have" in everybody's tool shed. Thanks John for alerting us to this product!
Cheers, Dave

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!

I just ran it around the mainline slowly for about four laps. I didn't get any Ross track spikes, but I did get a bunch of iron filings from cutting track. All of those places were vacuumed, but obviously the magnet reaches deeper. I have to do the same thing on my other loops and the sidings.
