PXIe-8301 Thunderbolt 3 thread pitch.

Solved!
Go to solution

What is the thread pitch/screw size for the holes next to the Thunderbolt 3 ports on the card?  Are there any readily available retaining clips that are compatible?  Thunderbolt 3 is great but in a busy production environment it's easily disconnected or damaged with a bump or tug.  I think the larger one is 4-40 but not sure about the smaller hole.

I think you need to get this cable retainer - I would assume these are compatible as Thunderbolt cables are fairly industry standard.

Santo_13,

 

Thank you but unfortunately the screw for the Sonnet is a 4-40.  The screw hole on the side is smaller.  I've looked through various manuals and forums but have not found a single mention of the specs or any hardware made for this.  There has to be something, thank you again.

Well, that is rather surprising, there is no trace of documentation of that screw.

That's an M2 nut above each connector. The holes at either side are 4-40
