cDAQ-9171 ground screw spec

[Jossi78]

Hi,

I'm missing a few of those ground screw for the cDAQ-9171. I suppose this ground screw follows some US standard—but which one exactly?
Annoyingly, the larger cDAQs like the cDAQ-9174 and cDAQ-9178 use a bigger screw. 😕

Hi Jossy,

The ground screw used on the NI cDAQ-9171 is likely a slotted #6-32 UNC screw, which conforms to a standard U.S. thread type commonly used for grounding. 

If you need a replacement, a #6-32 UNC slotted screw, approximately 1/4 inch (6–7 mm) long, should be suitable.

Best regards
