Hey. Quick (hopefully) question. Given a "standard" screw-held wheel, is there some degree of common relationship between axle length and track?

For example, do you take the track and minus 5mm to work out the necessary axle length? Like, a 65mm track would require a 60mm axle; 60mm, 55mm, etc...?

I only have a couple of knurled axle cars so far so don't have a great reference point for this and am trying to be economical in ordering parts to build up a couple of loose bodies. 

Thanks
