Re: Rivet sizing



Thanks, that helps a lot from the modeling viewpoint, but not from the prototype sizing understanding.

However, having half the story is a good start!

I just received my first Archer rivets today. I ordered the 2 "HO" sizes. The packages are labeled as follows:
# 26: 3/8" (nominal) Rivets (5/8" head diameter)
# 25 1/2" (nominal) Rivets (7/8" head diameter)
From this I take it they are talking 3/8" and 1/2" shafts with slightly larger heads. Hope this helps.

For the post-WW2 era, what determined the sizes of the round or button head compression rivets used in building freight cars?

What were the typical shank and head diameters used? . . . example: 1920s to 1940s gondola cars?

I presume the spacing or pitch was based on where the stresses (or observed failures) were typically the highest?

Do the raised rivet head decals reference the shank or their visible head diameters.

Were there standard practices published by the Master Car Builder's or ARA for rivet sellection, spacing, hole sizes, etc.?
