How to Hang Heavy Cabinets on Metal Studs

Hanging heavy cabinets on metal studs can seem daunting, but with the right techniques and materials, you can securely mount them. Here is a detailed guide on how to hang heavy cabinets on metal studs.

Selecting the Right Hardware

The key to successfully installing heavy cabinets on metal studs is using the proper hardware. Here are the essentials:

Toggle Bolts

Toggle bolts grip the backside of the wall and are ideal for heavy objects. When screwed into a metal stud, the wings flip out and hold firmly inside the wall.

Heavy-Duty Screws

For added strength, use coarse-thread screws specifically made for metal studs. They have thicker shafts and grip tightly. Self-tapping metal screws work well.

Solid Blocking

Installing a solid wood blocking between the studs provides extra reinforcement for heavy cabinets. Use 2x4s or 2x6s secured horizontally between studs.

Washers

Washers distribute weight over a larger surface area. Place oversized washers under the screw head and against the back of the cabinet.

Locating the Studs

Finding the metal studs is crucial for securely mounting the cabinets. Here are some tips:

• Use a stud finder specifically designed for locating metal studs. They detect changes in density.
• Check for screws/nails in the drywall indicating stud locations. Measure 16 inches on center for standard spacing.
• Use a neodymium magnet. It sticks to drywall screws/nails in the stud. Slide along the wall to locate them.
• Tap along the wall and listen for a solid “thud” sound. Hollow areas indicate empty space between studs.

Measuring and Marking Stud Locations

Once the studs are found, mark them for drilling:

• Mark stud center locations with painter’s tape. Measure for 16 inches on center.
• Mark the exact cabinet location with tape. Double check measurements.
• Mark drill locations on the tape, spaced 2-3 inches from cabinet edges.
• For corner studs, place marks 3-4 inches away from corners.

Drilling Pilot Holes

Always drill pilot holes to prevent screw stripping and provide more holding power:

• Use a carbide bit for smooth drilling through metal. Lubricate the bit for easier drilling.
• Drill pilot holes centered on the stud marks. Match pilot hole size to screw diameter.
• Drill slowly and smoothly to avoid damaging the metal studs. Let the bit do the work.
• Drill through just the surface of the blocking if using. Don’t go all the way through.

Installing Toggles and Attaching Cabinets

You’re ready to hang the cabinets onto the studs:

• Screw toggle bolts into the studs where needed for extra support. Leave wings partially open.
• Place cabinet against the wall. Insert screws through cabinet backs into pilot holes by hand first.
• Use washers under screw heads and against cabinet backs. Tighten screws with a screwdriver.
• For blocking, insert screws at slight downward angle into the edge of the blocking boards.
• Check cabinets for level and tighten all screws securely. Do not over tighten.

Tips and Warnings

Follow these tips when mounting heavy cabinets onto metal studs:

• Use a helper or temporary support to hold cabinets in place when fastening.
• Be extremely careful around electrical wiring inside walls. Avoid drilling into wires.
• Wear safety goggles when drilling metal and a dust mask if creating excess dust.
• Do not depend solely on drywall anchors for heavy items. Use studs for most of the support.
• Make sure cabinets are level side-to-side and front-to-back. Shim if necessary.

Hanging heavy cabinets securely on metal studs takes precision and the right hardware. But with careful planning and execution, you can achieve a solid, long-lasting installation. Follow these steps and tips, and you can confidently mount large cabinets on your metal stud wall.

Frequently Asked Questions

How much weight can you hang on metal studs?

Metal studs can typically support 15-20 pounds per square foot. For heavy cabinets, ensure you hit multiple studs to distribute the weight. Add blocking between studs for very heavy cabinets over 150 pounds.

What size screw do you use for metal studs?

For most cabinet installations into metal studs, #10 or #12 pan head screws with a coarse thread work well. Use 1 1/4″ to 2″ lengths. Self-tapping metal screws are ideal.

Can I use drywall anchors on metal studs?

Drywall anchors do not grip metal studs as well as screws, so they should only be used as supplementary support. Rely mainly on screws into the studs themselves for heavy cabinets.

What kind of drill bit is best for metal studs?

Carbide drill bits specifically for metal cut through metal studs cleanly and smoothly. Lubricate them to prevent binding. Standard wood bits can be used in a pinch.

Should I hit every stud when mounting heavy cabinets?

Yes, try to locate each stud underneath the cabinet length and attach into all of them. This distributes the weight evenly and provides maximum strength. Add blocking if needed.

Conclusion

Installing heavy cabinets on metal studs takes more skill and preparation than on wood studs. But with the right hardware, locating techniques, drilling practices, and installation tips, you can securely mount large cabinets onto your metal framed walls. Just be sure to find all the studs, reinforce with blocking, pre-drill holes, and use toggles and screws specifically made for metal. Follow these best practices outlined above, and you will gain confidence hanging hefty cabinets on metal studs.
