[Accrs] Common Metric Screw Sizes

[Alameda County Central Railroad Society]

I wanted to check to see what the common metric screws size are for O scale models.  Anyone know what that might be?


In HO scale the two most common sizes are M2.0 and M1.6.   Since everything, most everything, has been made in China the 2-56 screw is history now and is very over sized.


Anyone know what that might be?
