A: yes, this should be fine
A: A stud is pine wood. A soft wood. Normally you use a coarse thread screw when using soft wood. A fine thread screw, like this one is normally used when screwing into hard wood. Exe., oak, maple, walnut etc. This screw may strip out in soft wood.
A: Yes, if you have enough torque from your driver, or if the stud is relatively soft
A: Using this screw on 20g steel might be an issue. Majority of screws will go in with effort. Best use “self drilling screw”, this will make it easier and eliminate needing to drill holes.
A: no, no need. Just drill them in.
A: most drywall screws are self tapping in thin stud material. careful with over sinking, once perforated manage drill speed.
A: No you don't
A: I would test it, they may pierce that thin of metal but if not, pre-drill
A: Hello bruce, The phosphate coating is to aid in rust resistance. Drywall mud contains a lot of water so the coating protects the screw from the moisture content surrounding it. I hope this helps. Cheers, Chris
