Installing cabinets on metal studs requires some special considerations compared to wood stud walls. Metal studs are thinner and lack the wood grain that provides grip for screws, so you need to take steps to ensure your cabinets mount securely. With the right preparation and materials, attaching cabinets to metal studs is a straightforward process.

Benefits of Using Metal Studs

Before going over the installation process, let’s look at why metal studs are used in the first place:

Strength – Metal studs provide tremendous strength despite their thin profile. They are not prone to warping or rotting like wood studs.
Fire resistance – Metal does not burn, so metal stud walls have excellent fire ratings. This added safety is ideal for kitchens.
Consistent quality – Metal studs have a uniform thickness and lack imperfections found in wood. This makes installation easier.
Thinner walls – Metal studs take up less space than 2×4 wood studs, allowing thinner, space-efficient walls.
Resists pests – Metal deters termites and other pests from damaging the wall’s structure.

While working with metal studs differs from wood framing, the benefits often outweigh the small learning curve. Now let’s look at how to mount cabinets securely.

How to Locate Studs in a Metal Frame Wall

Locating the metal studs is the first step in cabinet installation. Here are the best ways to find them:

Use a stud finder – Electronic stud finders work on metal just as they do on wood studs. Slowly scan the wall until the stud finder detects an edge.
Look for drywall seams – Screws attaching the drywall often line up with the studs. Look for drywall seams and then measure 16 inches over to locate additional studs.
Use magnets – Magnets cling to drywall screws or the metal studs themselves, helping you find them. Neodymium rare earth magnets work best.
Check plans – Refer to the building plans to find the stud layout in the walls. Studs are usually spaced 16 inches apart.
Knock and listen – Tap gently across the wall surface and listen for a change in sound when you hit a stud.

Once you locate the studs, mark them for reference when mounting the cabinets. Now we’re ready to attach them.

Materials Needed for Installation on Metal Studs

Installing cabinets on metal studs requires specific fasteners and tools designed to grip the smooth metal surface. Here are the recommended materials:

Self-tapping screws – Specialty screws that cut their own threads into the metal as they turn. Use at least 2-1/2″ lengths.
Hollow wall anchors – Expand inside the wall cavity for anchoring to thin-gauge metal studs. Spring toggles are a good option.
C-clips – Metal clips that snap into C-shaped slots cut into the studs to hang cabinets.
Saw to cut slots for C-clips – A reciprocating saw works well. Make slots 1-1/2″ long to insert clips.
Impact driver – Provides force needed to drive self-tapping screws into metal. A drill/driver also works.
Stud splicing materials – Metal plates or wood blocks to join studs for added support.
Level – To check cabinets for plumb during installation. Laser levels work great.

Having the right supplies prevents frustration and ensures your cabinets mount securely on the metal stud wall.

How to Attach Cabinets to Metal Stud Walls

With the studs marked and the proper materials on hand, you’re ready to mount the cabinets to the metal stud wall. Follow these steps:

1. Position Cabinets and Mark Locations

Set cabinets in place and use a level to make sure they are plumb.
Mark the wall through mounting holes in the cabinet backs or rails to locate attachment points.
Make sure at least two mounting holes line up over each stud for stability. Expand holes if needed.

2. Install Hollow Wall Anchors

For holes that don’t line up with studs, install hollow wall anchors.
Hammer the anchor into the hole until the flange is flush with the wall.
When the screw is inserted, the anchor expands in the wall cavity.

3. Drive Self-Tapping Screws into Studs

For holes that hit studs, use self-tapping screws.
Drill pilot holes through the cabinet backs first for easier driving.
Drive screws directly into the studs. The threads will cut into the metal as they turn.

4. Use C-Clips for Added Support

For heavy upper cabinets, also install C-clips into slots cut into the studs.
Use a reciprocating saw to cut 1-1/2″ slots into each stud at cabinet height.
Insert C-clips into the slots and hang cabinet rails over them.

5. Splice Short Studs If Needed

If a cabinet only hits a short stud section, splice it first.
Use a metal splice plate or wood block screwed into the stud on each side.
The cabinet will then have a continuous backing surface to attach to.

6. Check for Secure Attachment

Tug on the cabinets once fully installed to verify secure mounting.
Fill any gaps around anchors or screws with shims if the cabinet moves.
Use decorative trim to hide shims if cabinet sides are exposed.

Follow these steps carefully, and your cabinets will enjoy rock-solid mounting on the metal stud wall.

Hanging Upper Cabinets on Metal Studs

Upper cabinets require extra care during installation to attach them securely on metal studs:

Reinforce the studs above and below the cabinet with wood blocking. This gives anchor points to keep them from pulling off the wall under weight.
Make sure the cabinet rails align perfectly with the studs. The bottom screws must hit the studs to support the weight.
Use hollow wall anchors in addition to screws driven into the studs for each mounting hole. More points of contact provide stability.
Drive at least 3-4 screws through the cabinet’s hanging rail into each stud. Longer 3-1/2″ screws provide better grip.
Consider using metal wall cleats or ledger boards to provide more screw points across multiple studs for heavy cabinets.
Place a solid wood shim above upper cabinets and drive long screws through it into the header stud. This helps support the weight.

With multiple heavy-duty anchors into reinforced studs, upper cabinets gain the sturdy mounting required for metal stud walls. Take time during installation to attach them securely.

Tips for Successfully Installing Cabinets on Metal Studs

Follow these additional tips when mounting cabinets to ensure a smooth installation process:

Use high-quality hex-head self-tapping screws designed for metal studs. Improper screws are prone to breaking or pulling out.
Drill small pilot holes before driving screws to prevent stripping them or damaging studs during tightening.
Splice short stud sections together for continuous support using splice plates or wooden blocks.
Slow down the screw speed on your drill/driver to prevent over-tightening and stripping of fasteners.
Double check for plumb during installation. Metal studs lack forgiveness that wood framing provides.
Consider using metal wall cleats to span multiple studs and gain more anchoring points for heavy cabinets.
Attach drawer slides and shelves after mounting cabinets. The base needs to be solidly anchored first.

Following proper techniques tailored for metal studs takes the frustration out of cabinet installations. Take the necessary steps, and you can achieve strong, long-lasting results.

Mistakes to Avoid When Attaching Cabinets to Metal Studs

It’s easy to make mistakes when installing cabinets on metal stud walls if you’re not accustomed to their unforgiving nature. Avoid these common pitfalls:

Not reinforcing upper cabinets enough leading to pulled-off cabinets.
Using drywall screws that lack the strength to hold in metal studs.
Depending on hollow wall anchors alone without also screwing into studs.
Failing to splice short stud sections resulting in inadequate support.
Not pre-drilling pilot holes causing screws to strip out of the studs.
Using standard C-clips that can pull out instead of flanged C-clips that grip better.
Forgetting to shim gaps behind cabinets that lead to movement.
Driving screws too tight causing them to snap or spin freely without gripping.
Not checking for plumb allowing cabinets to torque and pull away from the wall.

With attention to detail and the right materials, you can avoid these mistakes. Take your time and do the job right.

FAQs About Attaching Cabinets to Metal Studs

Here are some frequently asked questions about mounting cabinets onto metal stud wall framing:

Q: Can I use wood screws to attach cabinets to metal studs?

No, wood screws lack the specialized threads needed to grip and hold in metal. Always use self-tapping metal screws specifically designed for fastening into light gauge steel.

Q: What kind of anchor works best for metal stud walls?

Spring toggle anchors are ideal for thin metal studs. They compress during insertion and then expand behind the wall surface. Choose at least 1/4″-20 size anchors for the loads.

Q: Do I need special tools for driving screws into metal studs?

An impact driver allows you to deliver added driving force and is highly recommended. Use the proper driving speed and an adjustable clutch to prevent stripping screw heads.

Q: Can I just use C-clips instead of screws into the studs?
