Overview
This is a Grip-Rite #8 x 3 inch drywall screw with fine thread and a sharp point, sold in a 1 lb box. Fine thread and a phosphate coating point it at light gauge steel stud framing rather than wood.
The 3 inch length is longer than a typical single layer drywall screw, which fits jobs like double layer drywall or furring over steel studs where the screw has to reach through more material. Fine thread is the detail that separates it from a coarse thread wood screw, since fine thread is meant for steel track rather than wood framing.
- #8 x 3 inch, fine thread
- Sharp point, no pre-drilling needed
- Phillips bugle head
- 1 lb box
Who it's for
Useful for someone fastening drywall into light gauge steel studs, or building up multiple layers of board. Not the choice for wood stud framing, where a coarse thread screw holds better.
Pros and cons
- Fine thread matched to light gauge steel stud framing
- 3 inch length reaches through double layer board
- Bugle head countersinks flush for a smooth finish
- Not suited to wood stud framing
- Sold in a small 1 lb box rather than a bulk tub
Performance notes
The sharp point and fine thread combination is designed to bite into thin steel track without pre-drilling, while the bugle head lets the screw countersink into the drywall face for a flush finish. The phosphate coating is meant for paint and joint compound adhesion, not exterior corrosion resistance.
