Weaver used #2-56 machine screws to mount their trucks.  The length may have varied a bit depending on the specific car configuration.  A common length was 3/4"; however, they may have used a shorter length screw on the flatcars...I'm not sure.  Just measure the length of the screw that's holding the other truck and you'll have the answer!

I have hundreds (in various lengths) on hand in my parts supply as I do a lot of work with Weaver trucks.  If you don't have any luck finding them locally, send me an email and I'll gladly hook you up with a few of each length.

Does anyone know what the specific size of the Weaver screw is? That would be a good jump off point on line or when I go into Ace.

Just a suggestion, the other end of your freight car still has the truck attached, correct? Why not take THAT screw out, take it with you to your local hardware store, and ask them to match it?

My repairman says he can find screws for Atlas and Weaver at ACE Hardware.  

Yes - hardware stores are always a place to start when looking for...hardware. They won't have the very small screws found on Asian brass locos, but 2-56/4-40 and other "Lionel/MTH screws" are possible. Just take another one with you, if you have it, for a starting point.

And, Radio Shack has been a source of 4-40/2-56 nuts and bolts in the past. We still have one; drove past it last Saturday; open.

I tried that. Was asked “what is it for” and was told “we don’t sell screws for things like that”

helped myself and ended up with screws that looked correct but didn’t fit right.

i did a bit of leg work on this and the best advice I was given was “ask someone specifically what screw you need” so that’s what I did.

thanks to all who replied, now at least I have some numbers to use when looking so I’m not just guessing!

Just my opinion but, I would sure find a different/better hardware store to do my shopping. All the person had to do was find a nut that looked like it would accept your screw, and thus you now know the exact tread size. Besides, it is none of there business what the screw is for,,,,,,,,,just sell me some more!

Again, simply try different nuts on your screw sample, until you find the correct one.

My guess is a 1" 2 56 machine screw.   Some were shorter, but when changing Weaver plastic side frame trucks, to die-cast trucks, the longer screw were require.  Care needs to be taken, the screw can penetrate the hopper.   

 

That’s why it’s important to look at/measure the length of the other remaining screw.  I doubt they’re 1” long on a flatcar...but I suppose anything is possible.  At least he knows now to look for 2-56 machine screws...that is what Weaver used.

I bought my supply through Fasten-all.  I got 100 2-56 x 1 in black Phillips pan head screws for about $5.  The real trick is to only buy one size...1 to 1.5 inch long and cut them to my needs.  Everybody already has the tool for this!  Check out your wire cutters.  Around the pivot point is a series of holes for several size screws to trim them.  You may have to look around for a pair with 2-56 since it is as common.  The cutters are also available in metric...
