I recently purchased Swiss made screwdrivers, Horotec brand, with the perfect tip to remove links.
I got a screwdriver with 1.6mm blade for my Rolex watches, and another one with 1.8mm blade for my Omega watches. They work great and they do not damage the screws at all.

Here is picture of screwdriver tips taken from link above. Note, I am not associated in any way with Otto Frei, I am simply a satisfied customer.
Also, before putting the screw back into the bracelet I use the tip of a pin to put minuscule amount of low strength loctite threadlocker #222 on the screw. I purchased this at Amazon:
