How to Hang Cabinets on Drywall with Metal Studs
Hanging cabinets on drywall that has metal studs requires some special considerations compared to mounting on wood stud walls. Proper planning and preparation are key to ensuring a secure installation that will support the weight of the cabinets over time. In this comprehensive guide, we’ll walk through the entire process step-by-step.
Choosing Appropriate Fasteners
The first critical decision is which fasteners to use for mounting the cabinets to the metal studs. Here are some good options:
- Self-drilling drywall screws – These have a sharp point that can penetrate the metal stud. Look for screws that are 1 5/8″ to 2″ long to ensure they grip the stud securely.
- Toggle bolts – These insert through a drilled hole in the drywall and then open up on the backside to grip the stud. They provide very sturdy mounting.
- Hollow wall anchors – Plastic anchors insert into pre-drilled holes and expand inside the wall cavity. More suitable for lighter loads.
Self-drilling screws are the fastest and easiest option for most cabinet hanging jobs. Toggle bolts provide the strongest grip.
Finding the Studs
The next step is locating precisely where the metal studs are behind the drywall so you can attach the cabinets directly to them. Here are a few ways to find them:
- Use a stud finder – Electronic and magnetic stud finders can detect nails/screws in studs through drywall.
- Magnets – Move a strong magnet across the mounting area until it adheres to screws/nails in the studs.
- Knocking – Tap gently across the wall and listen for a solid “thud” sound indicating a stud.
- Measure – Studs are often at 16″ or 24″ intervals from a corner or edge. Measure and mark where they likely fall.
Dedicate time to finding studs precisely before proceeding with installation. It’s crucial for proper support.
Pre-Drilling Holes
Once you’ve marked stud locations, pre-drill holes for your fasteners using a bit slightly smaller than the screw diameter. This prevents stressing or cracking the drywall during screw installation.
For self-drilling screws, use a 3/32″ bit. For toggle bolts, drill a 1/2″ hole through just the front of the drywall. Pre-drilling ensures cleaner fastener installation.
Installing Cabinet Hanging Rail
Most cabinets have a hanging rail along the top back edge. Secure this directly to the metal studs with your fasteners.
Position the cabinet, align the rail over your stud marks, and drill in screws or toggle bolts through the pre-drilled holes. Sink screws flush with the rail.
Proper rail installation is key to preventing sagging. Ensure every stud is engaged along the cabinet length.
Securing Cabinets Together
Once each cabinet is securely fastened to the studs, connect them together through the sidewalls.
Pre-drill holes through the overlapping cabinet sides, making sure not to drill completely through both sides. Insert short screws to draw the cabinet sides flush and rigid.
Clamp cabinets tightly together while fastening for best alignment. Fill screw holes with wood filler for a clean look.
Important Installation Tips
Follow these tips for a flawless and sturdy finished installation:
- Support base cabinets on a ledger board attached to the floor rather than hanging from the wall.
- Use shims behind the hanging rail to plumb and level cabinets and fill any uneven gaps.
- Run a level wooden brace across upper rear corners of tall units for added stability.
- Load cabinets gradually, starting from bottom to top, to check for sagging issues.
- Confirm final installed cabinets are perfectly level and plumb. Make any necessary adjustments.
- Caulk along the countertop-wall and cabinet-wall junctions for an air-tight seal.
Proper planning and careful installation ensures your cabinets mount securely on metal stud walls and serve beautifully for years. Now let’s look at some common questions.
Frequently Asked Questions
What size screws should I use to hang cabinets on metal studs?
Use #10 or #12 pan-head self-drilling drywall screws that are 1 5/8″ to 2″ long. This ensures adequate grip length in the metal stud through the drywall.
How do I locate the metal studs behind a finished wall?
Use an electronic stud finder, magnets, or knock along the wall while listening for solid thuds indicating studs. Measure 16″ or 24″ intervals from corners.
Should I pre-drill holes for screws in the metal studs?
Yes, always pre-drill holes the same diameter as the screw shank (not threads). This prevents screws from bending when fastening.
Can I use toggle bolts instead of screws to hang cabinets?
Yes, toggle bolts provide extremely strong mounting. Just pre-drill slightly larger holes through the wall, and take care when tightening bolts.
How much weight can cabinets handle on drywall with metal studs?
With proper screws into the studs and reinforcement, cabinets can safely handle 50-60 lbs per foot of cabinet length.
How do I ensure the cabinets mount flush and even on the wall?
Use shims behind the hanging rail to level and plumb the cabinets. Tighten screws into solid stud contact. Check for any gaps before loading.
Should I attach a ledger board for base cabinets to sit on?
Yes, affix a ledger board securely to the floor rather than hanging base cabinets. This provides better support under their weight.
Conclusion
Installing cabinets on drywall with metal studs is very doable with the right techniques. Carefully choose your fasteners, accurately locate the studs, pre-drill all holes, and take care to mount the cabinets plumb, level, and reinforced. Employ tips like using ledger boards and braces to ensure a stable finished product that will last for many years of service. With attention to detail, you can achieve a beautiful and functional kitchen built on a metal stud frame wall.
