I need help identifying these screws and more importantly the screwdriver required to remove them. I believe they are pozi screws, but am not sure what size bit or screwdriver I’d need to remove them. They are holding the tweeter bracket for B&W CDM1 Speakers. I’ve attached a couple photos. Appreciate.

That's a Pozidriv. It's a variant or further development of the Philips screw: https://www.albanycountyfasteners.com/blog/what-is-pozidriv-is-it-different-from-phillips/
It's hard to tell from the picture, but I bet it's a PZ1. Could be a PZ2. That would match up well with the M4x18 mm size listed on the BOM.

You want a #2 Pozidrive screwdriver. If you don’t have one you can try a #2 Philips they usually work just fine for pozi.
I’ve begun the process of stripping them and I’m not in the mood to have to exact them if I do. I thought by the description in the B&W manual someone would know. Is there a size number ?
Philips will cam out of a Pozi screw in high torque application but for removing some screws holding a tweeter bracket to wood I think a Philips will work just fine.
Well... The BOM does list the screw as "M4x18". A similar screw here: https://www.trfastenings.com/Produc...chine-Screws/Pan-Head/PoziDriv/TR00009823-100 lists the drive as PZ2.
So +1 for PZ2.
McMaster-Carr has Pozidriv screwdrivers.
