Missing M.2 Standoff for Precision 3640
Hi,
Does anyone know what type of M.2 stand off would fit the precision 3640 motherboard. Currently the motherboard does not have any stand offs for both M.2 slots just a screw as seen in the image below. I tried a few other stand offs but they don't fit as the size of the hole on the motherboard is too big.
I am not sure if an stand off is needed in this case as the M.2 connector is also quite low on the motherboard (height wise) so I am not sure if I should just be using that screw that came with the motherboard to attach the SSD without any stand offs.
If anyone knows what type of stand off would fit this motherboard or if it doesn't need one by design please let me know.

.
does the pic above show a M2X2.5 Dell ssd screw (from screw list in service manual) installed in a standoff?

I know this is a late response, but I just ran across this issue also. In both M.2 NVME slots there are riser screws already installed on the motherboard at the 2280 position. Those riser screws are necessary because approximately 2mm thermal pads are placed in the white sections of the motherboard labeled "thermal pad area". The riser screw supports the tail of the M.2 NVME so the card doesn't bend when tightening the screw.
The M2x2.5 screw actually threads into the riser screw. I cloned the original M.2 NVME to a larger drive and this is how I found it configured on my 3640 Tower from Dell. I ordered a 2nd M.2 NVME for slot 2 so I had to order additional M2x2.5 screws because my motherboard only had the standoff screw in slot 2 and was missing the M.2 NVME attachment screw.
