80-160 loose hood mounting ring

Had my 80-160 on vacation and noticed the hood was loose, I clicked it back into place, and it came loose again.

I noticed that there's a metal ring that that the hood clicks on to, and that ring is held in place by 4 super tiny screws, 3 of which have fallen out.

Does anyone know what size these screws are, or where I can find replacements (or a screwdriver small enough to turn these screws)?

Here's a picture for reference:

They could be JIS (Japanese Industry Standard) threads. Pop the last one out and then search on eBay.

So I inadvertently contacted Ricoh/Pentax Australia, they sent me an exploded diagram of the lens and identified the screw as part "CNL-B 1.4x2.5"

They had the screw in stock, but couldn't send it because I'm in the USA.

I contacted USA support, who told me to send the lens to Precision Camera for repair, which I'm not going to do for a simple missing screw.

Knowing the part number, I gather that 1.4 x 2.5 is the screw size, and that these screws on eBay will easily solve my problem, right?
