Wire Diameter
Drywall screws must not be eccentric, the simplest way to judge whether the wall screw is eccentric is the round head down on the table, see whether the thread is vertical, and also people in the middle of the head. If the screw is eccentric, the problem is that the power tool will shake when screwed, seriously damaging the material being screwed in. The longer the specification, the more troublesome it is to encounter this situation.
