Installing cabinets on metal studs requires some special considerations compared to mounting on wood studs. With proper planning and the right materials, you can securely fasten your cabinets and ensure they are level and sturdy. Here is a comprehensive guide on how to install cabinets to metal studs.
Steps to Install Cabinets on Metal Studs
Choose Appropriate Fasteners
Self-tapping screws specifically designed for metal studs are required. Standard wood screws will not work. The screws should be 1 5/8 to 2 inches long so they can penetrate the stud. Look for pan head or truss head self-tapping screws. Other options include toggles or molly bolts.
Locate the Studs
Use a stud finder to locate all the metal studs where cabinets will be installed. Mark the locations with masking tape or pencil. Measure and space the cabinets accordingly so at least 2 screws can be installed into studs on both sides.
Add Backing for Additional Support
For extra strength, cut 1×4 or 2×4 wood backing to fit between the metal studs behind where cabinets will be fastened. Screw the boards to the studs using self-tapping metal screws. This provides solid anchoring behind the drywall.
Use Drywall Anchors
For cabinet mounting locations that don’t line up with studs, use hollow wall anchors designed for metal studs. Toggle bolts that expand behind the wall are a good option.
Drill Pilot Holes
Drill 1/8″ pilot holes in the studs where screws will go. This allows screws to thread easily into the metal without binding up. Use a high speed steel drill bit for metal.
Mount Cabinets Level and Plumb
Use a 4 foot level to check cabinets are plumb vertically and level horizontally. Shim as needed between the cabinet bottom and floor to make any adjustments.
Drive in Screws
Use a clutch-drive drill/driver so screws are installed without stripping or snapping the heads off. Set torque low and increase slowly until screws are completely set. Take care not to overdrive screws.
Check for Wobble
After installing, check if cabinets wobble at all. Shims can be added at screw locations to eliminate any gaps behind the cabinet. Re-tighten any loose screws.
Tips for Installing Cabinets on Metal Studs
- When possible, plan cabinet locations to align with studs for maximum strength.
- Pre-drill oversized holes in the back of the cabinet where screws will go to allow for adjustment.
- Use fender washers under screw heads to prevent them from pulling through the cabinet back.
- Don’t rely solely on drywall anchors – always try to hit studs.
- Load heavier items like dishes in lower cabinets, not upper ones.
- Make sure cabinets are adequately braced together with fasteners like corner gussets.
Common Mistakes to Avoid
- Not finding and marking stud locations first.
- Using the wrong fasteners that are too short or don’t anchor properly.
- Failing to pre-drill pilot holes in the studs.
- Not checking for level and plumb as cabinets are installed.
- Overtightening screws resulting in stripping or breaking.
- Not fully engaging toggle bolts behind the wall.
- Neglecting to support adjacent cabinets for rigidity.
Frequently Asked Questions
How do I find the metal studs?
Use an electronic stud finder designed for metal studs. Move it slowly across the wall to detect stud edges. Alternatively, use small finishing nails to probe for studs and find their edges based on resistance.
What screws should I use?
Self-tapping metal screws between 1 5/8 to 2 inches long are best. The coarse thread and pointed tip are designed to drill into metal studs. Pan head, truss head, or hex washer head screws are good options.
Should I hit every stud?
When possible, align cabinets with studs and attach them securely into the studs. If sections end up between studs, use hollow wall anchors rated for metal studs as additional mounting points.
How do I ensure cabinets are level?
Use a 4 foot level on the cabinet face frame and floor as you install them. Shim underneath if needed until the cabinet is perfectly level left to right and doesn’t tilt down or up in front.
What is the best drill bit for pre-drilling?
Use a high speed steel drill bit made for metal cutting. This prevents the bit from getting dull or breaking. Drill a 1/8″ pilot hole in studs before driving screws.
Final Thoughts
Though installing cabinets on metal studs presents some challenges, taking a careful and methodical approach makes it entirely achievable. The key steps include using the right fasteners, locating all the studs, providing solid backing, pre-drilling properly, checking for level, and avoiding overtightening screws. Follow these guidelines and you can gain peace of mind knowing your cabinets are securely fastened to metal studs.
