[Amps] 3-500z socket

[gdaught6 at stanford.edu]

I have a new ceramic Johnson socket for a 3-500z that I'd like to use 
to replace a socket with filament pins which are VERY loose.  The 
trouble is, the new socket is VERY tight.  

Does anyone recommend a lubricant of any kind?  What is the best 
plan?

Thanks in advance es vy 73,
