Couplers for Sun DB13W3<->VGA DE15 adapter

It works great, but the ends of the standoff bolts without nuts come together where the VGA cable meets the adapter; that is to say, the VGA cable's nuts are on the far side of the shell from its male end, and the adapter's nuts are on the far side of the shell from its female end. I'm wondering what I can put between the two to keep the cable from disconnecting from the adapter. Some searches seem to indicate I want some 4x40 (or 4-40) female-female (coupling) nuts; does this seem correct? -- Eric Christopherson
