What's the hardware on D-sub connectors?

[VanGoghComplex]

I'm making a custom cabling application and using a 15-pin D-sub connector. The female panel mount that I bought didn't come with the standoff hardware - the little hex posts that you screw the sides of the connector into.

What are those? 4-40? Some metric size?

Yeah, 4-40.

Searching on "vga jackscrew" should bring up some sources.
