[Boatanchors] Nice Rack Hardware?

[GDM]

Some years ago,  a poster to a BA list  described two part hardware used 
to rack mount equipment.  The first part is a stud threaded on each 
end.  That  screws into the rack holes.  Then you "hang" the equipment, 
followed by a knurled barrel shaped nut that screws onto the end of the 
stud sticking out through the equipment holes.

Particularly nice for hanging heavy equipment.   You don't have to hold 
things up with one arm while trying to get a rack screw started with 
another.

I bought about 50 of them at that time and like them a lot.  
Unfortunately no name on them and the container I received them in is an 
unmarked small paper bag.

Obviously a different look then typical rack screws, but I like the the 
ease of use and the unique appearance.

Any one know the name or source?
