Feb 9, 2021 at 13:59 comment added Solar Mike No, the screwdriver will have two points of contact...
Feb 9, 2021 at 13:56 comment added loStraniero I think the problem you are describing is more related to points of contact and grip? A larger screwdriver will have contact on the entire screw head compared to a smaller one, thus being able to transfer a larger moment. I wonder if not your answer together with kamran's answer is the one I am looking for.
