Which screw size for M.2 slot

[Stevehere]

I have the Slimline 270-p014

I installed an SSD drive in the M.2 slot and I am impressed with the performance on my first day.

I did attach a heatsink to the SSD.

However and this is my question:

I cannot figure out the size of the screw to secure it to the motherboard

The attached diagram shows the M.2 slot at the bottom of the motherboard.

To the left are two posts, the nearer one to the M.2 slot is not the problem but the one to the left of that is (just to the right where it says front usb).

It does not take a typical computer screw to secure a PCI to the motherboard.

Anyone any idea of the size I need?

Thank you

Hello and first of all thank you to help us. I Have a Pavilion Desktop with the motherboard Willow2 ( https://support.hp.com/it-it/document/c05954013 ). I bought an additional SSD m.2 but to fix it I don't have the right screw. I tried to put a couple of small ones I had at home but it wasn't the right one. Do you maybe help me to discover which size that motherboard's screws need and also (if you know) where I can buy a couple of ones?

I thank you in advance.
