To clarify, the screws are not (Japanese Industrial Standards) screws. Those were discontinued as a standard in 2018 and these screws do not have the JIS dimple marker on them. The current ISO (International Organization for Standardization) 8764 and DIN (Deutsches Institut für Normung) 5260 replaces the JIS screw standard. If you have a modern Phillips screwdriver or bit that conforms to ISO 8764 or DIN 5260 it will be compatible and work perfectly with these screws, if you have an old or non-conforming one it could strip them, though these screws are going into plastic so if you're being careful and not overtightening them it would be unlikely. Always check the fitment of a driver to a screw before applying force to it. A JIS screwdriver will work with them, I have that same Vessel impact screwdriver and it's great for tapping screws loose with a hammer, but it isn't explicitly necessary and there's no need (other than a tool addiction) to buy tools for a discontinued standard when you might already have a backwards compatible Phillips on hand, or inexpensively and locally available.

Thanks for the information, DMONKEY. I looked up JIS screws.

The screw in the center is an example of JIS screw - see the dot?

I went and bought 2 Vessel screwdrivers from Amazon based on this video.

I already have some #3, #2, #1, #0 and #00 Philips screw drivers in my tool bag.

Some of the inexpensive Philips screw drivers bought from the bargain bucket at the
local Aubachon hardware store crack the 4 blades on trying to loosen just one or two
old rusty screws. You get what you pay for.

The oldest Philips screw drivers lying in the bottom of my tool box are Craftsman's.
Purchased from from SEARS years ago. The heads do look different - more rounded and
have a larger point than the black magnetic sharp tipped ones I recently bought from Harbor
Freight.

These old SEARS screwdrivers never cracked but they can round out brass wood screws
with Philips heads and do not fit properly in drywall screws so they are not used much.
