Review on 100 Phillips Drywall Screws by Prime Line - MPSC7849 by Louis Mechtak

First of all I can't believe you can have something like a poor quality drywall screw but that's about it. If you plan on using them for simple, low-level projects and with very, very soft wood, you're fine. I pre-drilled the holes (using pine, not hardwood), set the torque to mid-point, and still snapped off the screw heads. My son noticed that the heads do not match the screw shank. In fact, all screw heads were at a slight angle. This meant that when the head of the screw hit the wood, the wood twisted the head and it broke off. I have the same box. They are useless.
