Columbia Dropout Screw Inquiry

[Rudy Rude]

Does anyone know the appropriate dropout screw specs(thread count, pitch etc.) for a 37 Columbia? I tried threading in a dropout screw from my 42 Shelby Travler w/no luck, the threads seemed different. I assumed they might be the same. Here's a pic of the dropout (forged): viewtopic.php?f=6&t=28346

Thanks!

I cant tell you what size it is but I can confirm that it is an odd thread. I had to buy expanding bolts that go into drywall at True Value to fit mine.
