First time hanging on 20-gauge steel studs at 16" o.c.

Screws: Use #10 or #12 self-drilling (Tek) screws, 3/4" to 1" long. They cut through steel without pre-drilling. Wood screws won't work — they're not self-drilling and will bind.

Screw placement: 7/8" from edge of stud flange. Don't overdrive — flush or slightly below surface. Overdriving can deform the stud.

Working direction: Steel studs are lighter and more flexible than wood. Work from one end, pulling studs back into place as you go. Use a stud puller or clamps to keep alignment.

Studs themselves: 20-gauge is thin — easy to damage. Handle carefully. They're also hollow, so avoid crushing the flanges when screwing near ends.

Tools: Use a drill/driver with a clutch. Impact drivers can over-torque and strip screws.

Safety: Steel studs conduct heat/cold and are noisy. Wear gloves — edges are sharp.

Code note: Check local building codes for screw spacing requirements — typically 12" o.c. along edges, 16" o.c. intermediate supports for drywall.

Pro tip: Snap a chalk line for consistent screw height. Steel doesn't shrink or swell like wood, so you don't need to worry about seasonal movement.

Key differences for 20-ga steel studs @ 16" o.c.:

Screws: Use fine-thread, self-drilling drywall screws (S-12 or similar). Coarse wood screws strip the thin flange. Length: 1" for 1/2" board, 1-1/4" for 5/8". Drive flush — don't dimple paper; steel won't "give" like wood.

Stud orientation: Flanges must face the same direction (usually all open-side right). Check every stud — twisted studs = wavy walls. Knockouts align for plumbing/electric; don't cut flanges.

Fastening pattern: 12" o.c. on walls (IRC R702.3.5), 8" o.c. on ceilings. Start center of panel, work outward. Steel deflects more; this prevents oil-canning.

Stud quirks:

• 20-ga (33 mil) is non-structural — no point loads. Don't hang cabinets/heavy items without blocking.
• Flanges are sharp — wear gloves.
• Studs twist easily; brace top/bottom track before sheathing.
• Use resilient channel or hat channel for ceilings — direct-screw to 20-ga joists risks screw pop.

Tools: Screw gun with depth-sensitive nosepiece (not impact driver). Magnetic bit holder helps.

Code: IRC R603 (cold-formed steel), R702.3.5 (fastening). Check local amendments.

Pro tip: Snap chalk lines on studs before lifting sheets — hard to find flange centers through rock.
