What Size Screws for Metal Studs?
Metal studs want fine threads and exact lengths — coarse wood screws strip out of thin steel, and long screws punch through to the other side. The chart: #6 fine-thread for 1/2 and 5/8 in board on light-gauge studs, self-drilling #6–#8 for 20-gauge and heavier, longer screws for double layers. Match thread, point, and length to the stud gauge.
What to Look For
- Fine thread always on steel — coarse threads strip out of 25–20 gauge studs.
- 1/2 in board: #6 x 1-1/4 in; 5/8 in board: #6 x 1-5/8 in — the two sizes that hang 90% of walls.
- 20-gauge and heavier: switch to self-drilling points — sharp points skate on thick steel.
- Double layers: step up to #8 at 2 in or longer to reach through both sheets into steel.
- Drive to dimple, never to tear — 8 in on edges, 12 in in the field per GA-216.
Top Picks
1. Fine-thread drywall screws, #6 x 1-1/4 in, bulk box Best overall
The commercial drywall staple — fine threads bite light-gauge steel without stripping, bugle heads dimple cleanly, priced by the thousand for whole floors.

Fire-rated and ceiling board need the extra length — same fine thread and bugle head, sized to bury properly in steel through thicker gypsum.
Check price on Amazon →3. Self-drilling drywall screws, #8 x 1-1/4 in Best for heavy-gauge studs
Drill points cut 20 to 18-gauge steel that stops sharp-point screws cold — for structural studs, shaft walls, and anywhere light-gauge rules end.

Avoid
- Coarse-thread wood screws in steel studs — they strip the moment they bite.
- Sharp-point screws in 20-gauge-plus steel — they skate, snap, and mar the stud.
- Screws long enough to pierce the far side — points in the next room snag wire and insulation.
- Overdriving past the paper — torn faces hold nothing; set the clutch and trust the dimple.

FAQ
What screws for drywall on metal studs?
#6 fine-thread drywall screws — 1-1/4 in for 1/2 in board, 1-5/8 in for 5/8 in board. Fine threads grip thin steel where coarse threads strip out.
Do you need self-drilling screws for metal studs?
Only for 20-gauge and heavier steel — light-gauge 25–22 gauge studs take sharp-point fine-thread screws. Structural studs, shaft walls, and 18-gauge track need true drill points.
How many screws per sheet of drywall on steel studs?
Roughly 28–32 per 4x8 sheet at GA-216 spacing — 8 in on panel edges, 12 in in the field. Ceilings and fire-rated assemblies run tighter schedules.
Can you use wood screws in metal studs?
No — coarse wood-screw threads strip out of thin steel instead of tapping it, leaving a spinning screw with zero hold. Always use fine-thread or self-drilling screws rated for steel.
