Use this guide to replace the antenna bar in your MacBook Pro 16" 2021.
For your safety, discharge the battery below 25% before disassembling your MacBook. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

Is there a source for the 9 tiny screws that hold down the antenna bar? Your guide describes them as 1.5mm P2 screws. The Apple manual calls them 1IPR (part number 923-06856). I've reached out to Apple and they don't sell them.
The screws described as P2 Pentalobe in the antenna bar removal step ARE NOT P2 Pentalobe fasteners! P2 tools strip out the heads on these. Per the Apple manual, the actual drive type is 1 IPR. Wera makes one.
