Inspiron 3910: Specs for WYT40 Standoff???

Hi,

Does anyone know the specs (height, thread pitch) for a missing NVME standoff for an Inspiron 3910?

The Dell part number is WYT40.

I know the screw is a M2x3.5, but the standoff is missing and I would like to get an aftermarket standoff locally.

Thanks in advance.
