How to Install Cabinets on Metal Studs

Installing cabinets on metal studs requires some special considerations compared to installing on wood studs. With proper planning and materials, you can securely mount cabinets on metal studs. Here is a comprehensive guide on how to install cabinets on metal studs.

Introduction

Metal studs are increasingly popular in modern construction for their strength, consistency, and fire resistance. However, their lack of solid anchoring points presents challenges for installing cabinets and other fixtures. Using the wrong fasteners can result in pulled-out or stripped screws.

The key requirements for proper metal stud cabinet installation are:

• Finding solid points to anchor the cabinets
• Using self-tapping screws specifically designed for metal
• Attaching reinforcement blocking between studs for added stability

When done correctly, your cabinets will be level, plumb, and securely fastened to withstand years of use. This guide will walk you through the entire process.

How to Install Cabinets on Metal Studs

Step 1: Locate Studs and Identify Solid Anchoring Points

• Use a stud finder to locate the metal studs. Mark the center of each stud.
• Identify solid horizontal points to anchor the cabinets. The top and bottom plates where the studs meet the floor and ceiling are ideal.
• Mark at least 3-4 anchoring points for each cabinet. Having multiple anchors prevents sagging or pulling out.

Step 2: Attach Reinforcement Blocking

• Cut 2×4 or 2×6 wood blocks to fit snugly between the studs at your desired mounting heights.
• Predrill holes in the blocks to prevent splitting.
• Use self-tapping 3-4″ screws to attach the blocks to the studs. Make sure they are fully secure.
• The blocks will provide solid horizontal anchoring behind the cabinets.

Step 3: Prepare the Cabinets

• Drill pilot holes in the cabinet back panels or rails where they will align with your anchoring points on the studs. Go slowly to avoid splitting.
• For added strength, install horizontal hanging rails along the top and bottom of the cabinet boxes.
• Make sure the cabinets are level and plumb before securing to the studs.

Step 4: Mount the Cabinets

• Use self-tapping screws (at least 2-1/2″ long) designed for metal studs. Do not use wood screws as they can strip out.
• Make sure to hit the studs or blocking with your pilot holes. Secure each cabinet at all anchoring points.
• Tighten the screws just until snug. Avoid overtightening.
• Check for level and plumb when all cabinets are mounted. Make any necessary adjustments.

Helpful Tips for Installing Cabinets on Metal Studs

• Use toggle bolts at anchoring points if there is no stud. They grip by clamping behind the wall.
• Apply painters tape to the drill point to prevent swarf from scratching the cabinets.
• Stagger adjacent cabinet screws to avoid hitting the same stud.
• Use fender washers for a wider surface area on the back side.
• Apply construction adhesive between cabinets and wall for added stability.

Common Mistakes to Avoid

• Not finding solid horizontal anchoring points. This can lead to sagging cabinets over time.
• Using screws that are too short. They should fully penetrate the stud or blocking.
• Stripping out screws by overtightening or hitting metal instead of a stud.
• Not piloting properly sized holes for screws. This can split cabinet backers.
• Only attaching at vertical studs. This puts all weight on a few points instead of distributing it.

Frequently Asked Questions

How do I find the studs behind drywall?

Use an electronic stud finder or knock on the wall and listen for solid vs. hollow points. Popping off outlet covers can also reveal stud edges.

What size pilot hole should I drill?

For most self-tapping screws, a 1/8″ pilot hole is ideal in metal studs. enlarge the pilot hole slightly in wood blocking or reinforcement.

Should I use lag bolts instead of screws?

Lag bolts are overkill for cabinet installation. proper self-tapping screws specifically designed for metal provide plenty of strength.

Can I use toggle bolts instead of finding studs?

You can use toggle bolts at points where there’s no stud access, but they should not replace screws into studs and blocking altogether.

Should I use epoxy, glue, or adhesive too?

Construction adhesive between the cabinet and wall provides extra stability and adhesion, but should not be used alone without mechanical fasteners.

Conclusion

Installing cabinets on metal studs presents some unique challenges, but is manageable with the right materials and techniques. The keys are finding solid horizontal anchoring points, using metal-appropriate fasteners, and reinforcing between studs. With proper planning to distribute weight across multiple studs and blocking, metal studs can provide a very sturdy cabinet installation that will last for many years. Follow the recommendations in this guide and you can gain confidence in securely mounting cabinets on metal studs.
