I see there are standoffs listed at 4-40 on the McMaster-Carr site,  
so it should be possible to buy nuts for standoffs.

However, I have a few scavenged #4 standoffs which I thought might be  
4-40 but recently bought 4-40 nuts that don't work.  The stand-offs  
appear to have more threads.  4-48?  Though for example, McMaster- 
Carr doesn't appear to sell those.  Maybe the standoffs I have are  
metric?
