Decent versions cost a lot more but are high tensile, and when used with a good quality allen key (again not El cheapo rubbish) will be far less likely to cause any damage
Screws are fine as long as people use either a proper "Turnscrew" or at least good quality hollow ground bits, again avoid the huge sets available for a few quid and buy the best available such as by Snap-on, they will last forever anyway
I agree with the above , I use an inch pound torque wrench ie lever type as opposed to a torque driver allen/hex heads are easier to torque accuratly I would have difficulty avoiding scratches with a turnscrew let alone screwdriver bit...
