       Box car screws
       By: Bobbo Date: May 26, 2020, 9:44 am
       ---------------------------------------------------------
       Does anybody know what screw size and thread the 9400 and 9700
       series box cars use for fastening the shell to the frame? The
       6464 series uses a #4 screw with a sheet metal thread, while the
       9400 and 9700 series use a machine screw thread. I tried gently
       testing with a 4-40 and a 4-36 tap, but neither one matched the
       thread. I am thinking that maybe it is metric?

       According to the Lionel service manual 1-9, page 6-1, the body
       screw for 9700 series boxcars is part #9700-25 which is a
       #4-40x1/4 flat head Phillips screw.

       Lionel service manual 12, page 17-2 calls out Lionel part
       #8405-5 screw which is a #2x5/16 Phillips head screw.

       TrainLarry,
       Thanks for the references. Mine is definitely not 4-40. I didn't
       know about the #2 screws which is why I suggested it might be
       metric. I will have to take the screw to my local hardware store
       to check it out. I always like to stick to the original, no
       matter what I am working on. Maybe in this case I shouldn't
       worry about it and just use the sheet metal thread 6464 screw,
       which I have plenty of (?)

       just a follow up for anybody reading this thread. I had the
       opportunity to check the thread in question and it is, in fact,
       4-40.

       Glad you identified the screw.
       For the future, a set of Imperial and Metric screw pitch gauges
       will come in handy to help identify screws.
