Bachmann Locomotive Screw Thread Pitches...?

Hi. I am working on making entirely new 3D printed body shells for a Bachmann HO Scale steam locomotive. I intend to attach the bodies to the old chassis, and I will have to tap the holes for the screws after the shells are printed. However, I don't know the thread pitch of the various body screws. If anyone could help me so I can buy the appropriate taps.

The screws in question, according to Bachmann's parts department, are:
10119
10597
10547
10619
10367

Thanks in advance for the help!
 
Good Morning and Welcome.

Hmmm, If the chassis only has holes for screws and not threaded, why worry about the pitch? I would think that as long as the screw goes through the thing you could use what you have on hand. If fact, you may decided to use a slightly bigger screw for a tad more holding power? That being said, does not Bachmann have a parts list for the loco?

Well, here's the thing: Sometimes it's the chassis or tender frame that's threaded, other times it's the body shell that's threaded.

In any case, Bachmann's parts list only lists the screws' part ID numbers--it doesn't specify their thread pitch, and I can't tell by looking at the screws themselves what their pitch is. So any help would be appreciated.
