Omen 15-dc1000 Series - screw sizes

[Formedras]

I've opened my laptop a few times for various purposes (replacing the SSD, cleaning out dust), but I've had a few issues with the case screws that the laptop came with. I've stripped a couple, misplaced a couple more. I need replacements, but I don't know what sizes the screws are.

I'm also planning on replacing the thermal paste due to high idling temperatures (60-70 degrees Celsius on the CPU, though the GPU idles fine closer to 40C), and knowing what screws are in my way there would be useful in case I strip one of those accidentally, too.

Don't worry about me voiding my warranty, it's already expired.

To rephrase my question more concisely:

What sizes of screws does my laptop (Omen 15-dc1000 series) use, both externally and internally?
