Correct shoulder screw information?

Classic Toy Trains Forum

Does anyone know what the proper shouldered screw is for attaching the valve gear to the side of the locomotive? I’ve been told it’s a 4-36 or a 6-32…I have only one of the original shouldered screws & it appears to have (3) threads and the shouldered portion makes up about 60% of the screw length.

I’ve tried using a 4-40 shouldered screw…however, the length is too short, but it does thread properly.

If anyone has any information on what the correct screw is for this AF model…I’d appreciate the information. Thanks one and all for any assistance!

I failed to mention…this is an ‘O’ gauge, pre-war AF model # 420 locomotive.

Mike,

Not that familiar with AF but you mite try looking thru Olsen Toy Train’s archives. Believe they have parts lists and additional info on most of the “O” gauge product. You’ll have to google them I can’t remember their web addy.

Hope this helps.
