Awesome, I checked their catalog and they got 'em, exactly what I need. 
Their part number for the HP one is 93040A108 (had to get out the caliper).

I'd recommend others check out this places' online catalog. As I was 
skimming through it, they seem to have a TON of various connectors, 
fasteners, etc. that I always thought would be impossible to find. They seem 
to have it all.

And for the record, these are called "Plunger-Head Captive Fastners" :)

Thanks Dwight!!
