Maybe if you go up a couple of sizes.  It's possible to actually twist off a brass screw with a screwdriver---they're that much less strong.  If that doesn't happen right away, corrosion will eat up brass in a season or two.  I had rubrails on a boat affixed with brass screws just fall off after two years.

Brass is mainly decorative;  bronze is structural.

For that matter, use stainless instead of bronze!  Stronger, generally easier to find, though not as attractive.

Fasteners.

Jamestown Distributors has silicon bronze screws at a much better price.  You can probably by a box of a hundred for what WM charges for 8.  They will also sell smaller amounts.

Thanks, I will check online and go with the bronze.

just a thought bearnkar. Using a bit brace (hand drill) when putting brass or even bronze screws. Maybe lube screws with some ivory soap and or drill a pilot hole/countersink. Especially those slotted screws.
