Thanks everyone. All those links came in handy.

Does anyone have any idea on how to secure 24 position straight header
pins to one of these project boxes?

With normal PCBs it would be solder that secures the pins, but this
obviously will not work with these plastic boxes. So after I find the
correct size drill to make the holes in the box for the pins I have to
use some sort of cement top keep the header in place.

the type of cement that's best used depends on what sort of plastic it is.


can you solder the header to a PCB and then bolt the PCB to the case?


another option could be drilling undersize holes for each pin and
forcing the pins in, but the website says that the case is conductive.

if you go this route expect in the ballpark of 1K resistance between adjacent pins.

Do you know of a site that sells cements for this purpose?

I thought about that, since the already existing PCB will already be
secured inside using stand-offs it makes this difficult.

I was just thinking. Since I'll be using stand-offs, perhaps I don't
need a conductive box.(Even though PCBs with circuits etched in them
are considered "static sensitive devices"). So I'm back to square one
as far as finding a place to purchase these boxes. So far the
distributors I've checked have huge minimum or they don't have the
size I need.

no, but plumbers do a lot of solvent welding of plastic, but first you
need to know what type of plastic.

how about a longer than usual header to compensate for the stand-offs?

static sensitivity depends on the circuitry inside the case (I'm
guessing EEPROMS, so it could be a proble)
