Model Railroading > Help - Coupler mounting screw Proto locos

I have a friend who is not local to a hobby show who is looking for replacement coupler box screws for a Proto locomotive.

Can anyone confirm whether the coupler box mounting screws on a Proto S3 (or SW800) are #2-56 screws?
I believe they are but there is a possibility that they may be metric.

Once I get the proper size, I will mail him what he needs.

Thanks.

Just had a thought, are these a plastic friction plug.

Somebody out there must have a Proto switcher of some sort. The frames are all similar.
I am in On3 scale so no Proto locos here.

Thanks to anyone who is willing to look at the underside of their loco.

Have replaced some of mine w/ 2-56 screws after using a 2-56 tap. Kadee sells them: www.kadee.com/htmbord/page246.htmww.kadee.com/htmbord/page246.htm

Thanks Andy,

I will send him some 2-56 screws and that should do the job.

Appreciate the reply. For a while there, I thought I was not going to get an answer.

Cheers...
