How to Hang Kitchen Cabinets on Metal Studs

Choose the Right Fasteners

Self-tapping screws are generally not suitable for attaching cabinets to metal studs. Instead, choose fasteners designed for metal:

• Sheet metal screws – These have sharp threads that bite into metal. Use #8 or #10 gauge, 1 1/4″ to 2″ long. Pre-drill clearance holes.
• Toggle bolts – The spring-loaded toggle wings compress to fit through holes then spring open behind the wall. Use 3/16″ to 1/4″ diameter bolts.
• Molley bolts – Similar to toggle bolts. The sleeve expands behind the wall. Use 5/16″ diameter bolts.
• Hilti bolts – Expansion bolts inserted into pre-drilled holes. Top choice for heavy cabinets.

Locate the Studs Precisely

Finding the exact stud locations is crucial for proper cabinet installation. Here are some tips:

• Use a stud finder designed for metal studs. They detect changes in density, not magnetism.
• Verify stud finder results by tapping along the wall and listening for a change in sound.
• Check for drywall seams as a clue to stud locations. But seams don’t always align with studs.
• Examine for screw pops that might indicate stud edges.
• Consider using magnetic stud finders to double check results. They may detect plumbing or other metal behind the wall.
• Make small drill holes to confirm stud edges, 1/8″ holes are easy to patch later.

Attach Horizontal Mounting Strips

Mounting strips provide a continuous fastening surface and reinforce the studs:

• Use 3/4″ x 3 1/2″ pre-drilled strips. Run them horizontal to the floor.
• Position strips to match cabinet height and spacing. Allow room for filler strips.
• Predrill clearance holes and attach with sheet metal screws into studs.
• Join strips over seams using splice plates.
• Use shims to level and fill any gaps behind strips.

Drill Clearance Holes in the Cabinet Back Panel

• Mark stud locations on the back panel.
• Drill oversized clearance holes approximately 1/2″ in diameter.
• Holes allow minor adjustments to align with the strips.

Fasten the Cabinets to the Strips

• Lift or temporarily brace the cabinet in position on the wall.
• Insert bolts through the clearance holes and tighten into the mounting strip using washers.
• Use lock washers or thread locking fluid to prevent loosening over time.
• Level the cabinet both horizontally and vertically as you fasten it. Make any adjustments needed.
• Cover exposed strip portions with trim or filler panels for a finished look.

Proper planning, finding the studs accurately, and using the right fasteners for metal studs will lead to success in hanging your kitchen cabinets securely. Take your time and don’t force bolts that don’t align correctly with the studs. With care, you can achieve a safe, sturdy installation.

Frequently Asked Questions About Hanging Kitchen Cabinets on Metal Studs

How do I find the exact stud location on a metal stud wall?

Use an electronic stud finder made specifically for detecting metal studs, and verify the results by tapping on the wall and listening for changes in sound. Also check for drywall seams and screw pops as clues. Make small drill holes to confirm stud edges if needed.

What fasteners work best for mounting cabinets onto metal studs?

Self-tapping screws are not recommended. Opt for fasteners made to grip metal like sheet metal screws, molly bolts, toggle bolts, or Hilti bolts. Match the size appropriately to the cabinet load.

Should I use a leveling rail system instead of mounting strips?

Leveling rail systems are an alternative option. They can save installation time compared to strips and provide easy leveling. However, rails may flex more than wood strips under heavy loads. Consider the cabinet weight when choosing.

What is the best way to find the studs for a partial height backsplash?

Use the same metal stud finding techniques in the lower wall area. Confirm with small drill holes if needed. The ends of countertops often align with studs, providing a clue to their location behind a backsplash.

How much weight can metal studs hold for cabinets?

With proper fasteners like toggles or expansion bolts, metal studs can safely support up to 500 lbs per stud. Spread loads over multiple studs whenever possible. Wall construction and stud gauge also factor in.

Conclusion

Hanging kitchen cabinets on metal stud walls is doable with careful planning and the right techniques. Locating the studs accurately is crucial. Use specialty fasteners made for gripping metal. Install mounting strips horizontally to reinforce the studs and provide a continuous fastening surface. With proper clearance holes and fastener selection, you can securely mount your cabinets onto metal stud walls. Taking a methodical approach will lead to a safe, stable result that lasts for years of heavy use.
