Lpc2000

Sorry for the off topic, but I was hoping someone here would know a 
source for 4-40 screws that come with a thread locking material pre 
applied to the threads.  When I was at another company they used to 
use them all of the time.  I've spent an hour or so searching the web 
and have come up with a company that will take your screws and coat 
them for you but none that sell common screws pre treated.

Does anyone know of a source in the USA?

I've been all over McMaster-Carr and Granger with no luck...

Thanks, and sorry again for the off topic.  The screws will be 
mounting a PCB with a LPC2194, so it's not tooooo far off topic :)
