- Wood studs
The standard, inexpensive coarse-thread bugle screw for hanging drywall on wood studs, and only for that job.
Pros
- Coarse thread grabs wood studs hard and pulls sheets tight without stripping
- Bugle head dimples the paper cleanly without tearing, ready for mud
- Phosphate coating helps joint compound adhere and it is cheap by the pound
Cons
- Phosphate is interior-only and will rust if used anywhere damp or outdoors
- Coarse thread is for wood studs, not metal studs (that needs the fine-thread version)
- #2 Phillips drive cams out more easily than star drive if the depth-setter slips
