How to Hang Cabinets on Metal Stud Walls
Installing cabinets on metal stud walls requires some special considerations compared to wood stud walls. Metal studs are thinner and have less screw-holding power than wood, so you need to attach the cabinets securely and compensate for the lack of strength. With the right preparation, materials, and techniques, you can successfully hang cabinets on metal studs for a long-lasting installation.
Getting Started with Hanging Cabinets on Metal Studs
Before you start installing cabinets on metal studs, follow these preliminary steps:
Materials Needed
- Cabinets designed for wall mounting
- Self-tapping metal screws in various sizes
- Hollow wall anchors or toggle bolts
- Wood blocking – 1×3, 2×3, or 2×4 lumber
- Wall stud finder
- Power drill
- Level
- Other common installation tools – screwdriver, tape measure, etc.
Find and Mark the Studs
- Locate all the metal studs using a stud finder suitable for metal.
- Mark the center of each stud using masking tape or pencil.
- Most metal studs are 24 inches on center, but double check for any irregular spacing.
- Also locate any electrical, plumbing, or other items behind the wall to avoid later.
Add Wood Blocking Between Studs
- Since metal studs alone are too thin to securely hold cabinets, wood blocking creates a robust mounting surface.
- Cut lengths of 1×3, 2×3, or 2×4 lumber to fit snugly between the studs at cabinet locations.
- Attach horizontally along the length of the studs using drywall or deck screws.
- Provide backing where both uppers and lowers will be installed.
Mounting Cabinets Directly to Metal Studs
Installing cabinets directly against the metal studs is the most straightforward method. Here are some tips for direct metal stud mounting:
Allow Proper Cabinet Spacing
- Review the manufacturer’s recommended spacing between cabinets and from adjacent walls.
- Mark stud locations on the floor and ceiling to map out cabinet placement accurately.
- Minor spacing adjustments can be made by moving a cabinet slightly off-center of the stud if needed.
Use Self-Tapping Screws
- Standard wood screws do not work well on metal. Self-tapping screws are designed to cut their own threads as they turn into metal.
- Use self-tapping screws in the size recommended by the cabinet manufacturer, commonly #8 or #10 size.
Drive Screws Through Back Panel
- Locate the studs behind the cabinet and drive screws through the cabinet back and into the stud.
- Using a screw every 12 to 16 inches provides good holding strength.
- Pre-drilling pilot holes prevents stripping out as you drive in the screws.
Consider Hollow Wall Anchors
- For added support, use hollow wall anchors designed for metal between studs.
- Drive an anchor screw at each corner of the cabinet and near the top hinge into the drywall only.
- This helps grab the wall board and reduce flexing stress on the stud screws.
Installing Cabinets on Wood Blocking
For maximum strength, cabinets can be installed on wood blocking attached horizontally between studs:
Position Blocking at Proper Heights
- Mark locations of uppers and lowers on the studs and attach wood blocking at those heights.
- Leave 11⁄2 to 2 inches above the cabinet top for hinge clearance.
- Make sure blocking runs the full width between studs where cabinets will go.
Attach Through Back to Blocking
- With blocking in place, set cabinets in position and drive screws through the cabinet back into the wood.
- Use at least two screws through the top and bottom horizontal blocking strips.
- This provides strong reinforcement compared to just using the metal studs alone.
Drive Screws Downward Where Possible
- In addition to back panel screws, use angle brackets to drive screws downward through the cabinet top into the blocking.
- This prevents any upward movement or separation over time.
- Angle brackets or L-brackets provide a 90 degree surface to mount flush and screw.
Use Toggle Bolts Where Needed
- At the sides of corner cabinets or areas without backing, toggle bolts grip the drywall from inside.
- Drill access holes through the cabinet sides first.
- Then insert bolts and tighten – they will rotate 90 degrees behind the drywall.
Tips for Hanging Upper Cabinets
Installing upper cabinets on metal studs follows the same principles but has some added considerations:
Provide Solid Mounting at Bottom
- The bottom of upper cabinets sees the most stress, so always mount into wood blocking here for strength.
- If no backing, drive extra toggle bolts into the wall at cabinet bottom corners and near hinge locations.
Use Cleats Along the Top
- Attach 2×2 or 2×3 cleats flat against the wall across two or more studs at the top.
- Drive screws upward through the cabinet top into the underside of the cleat.
- Distributes weight side-to-side rather than relying solely on studs.
Allow Proper Hinge Clearance
- Make sure any backing or cleats are positioned so cabinet doors have room to fully open and swing clear.
- Review hinge specifications to determine required opening radius.
- Wall materials that extend too far above the cabinet top also need to be trimmed back.
Provide Mid-Cabinet Support
- For wider upper cabinets, add support near the middle with extra blocking or metal brackets anchored into studs.
- Helps prevent sagging under heavy loads on shelving.
- Can also install wire tension rods or metal rails across stud bays for mid-span support.
Check for Secure Attachment
- Confirm that all upper cabinets are firmly anchored before loading to prevent pulling away from the wall.
- Try gently pushing/pulling on corners and opening/closing doors to test for any looseness or movement.
- Recheck and add additional fasteners if any weak areas are found.
Hanging Best Practices for Metal Stud Walls
Follow these general hanging tips and methods to safely and securely mount any cabinets onto metal stud wall construction:
Use Proper Screw Length
- Avoid using excessively long screws that penetrate deeper than needed into metal studs.
- Too long can hit electrical or plumbing inside.
- Optimal screw length should allow 1⁄2 to 3⁄4 inch embedment into the metal stud.
Drill Proper Pilot Holes
- Drilling small pilot holes prevents screws from binding up or stripping out the metal framing.
- Use a drill bit slightly smaller than the screw – e.g. 3/32 inch pilot for #8 screw.
- Let the screws cut their own threads into metal rather than forcing.
Distribute Weight Evenly
- Position cabinets to align over as many studs as possible to disperse weight.
- Wall anchors and cleats help transfer load side-to-side between studs.
- Avoid excessive spans which put leverage force on a few attachment points.
Allow Proper Screw Edge Distances
- Keep screws positioned 1 to 2 inches from cabinet edges and corners to prevent splitting the wood or metal.
- Proper stagger pattern helps transfer stress uniformly into the framing.
- Edge distances are less critical with metal, but follow wood screw spacing standards.
Use Molly Bolts at Sheetrock Only Areas
- At hollow areas of drywall between studs, molly bolts grip into the wallboard material.
- Drill access hole through cabinet first, then install bolt. Tighten until snug.
- Good for upper cabinets that can’t align with studs based on ceiling height.
Attach Corner Cabinets Securely
- Use an “L” bracket or equivalent metal corner brace inside corner cabinets.
- Attaches to adjacent wall with multiple molly bolts to prevent pulling.
- Important since corner cabinets have limited wall contact area.
Consider Weights and Loading
- Check cabinet specs to confirm capacities and live/dead loading limits.
- Heavier items should align over studs. Anchors alone may not be sufficient.
- For extremely heavy loads like dishwasher or range, provide dedicated backing support.
Conclusion
Installing cabinets on metal stud walls is best approached by using wood blocking between the studs to create a sturdy anchoring surface. Self-tapping screws driven into the metal studs provide good strength, and hollow wall anchors can add supplemental support. With proper planning and installation techniques, metal framing can support cabinets securely. Pre-drilling holes, using the optimal fastener length, distributing weight evenly, and reinforcing upper cabinets are key considerations when hanging on metal stud walls. Take the time to anchor properly, and the cabinets will look great and perform well for years to come.
Frequently Asked Questions About Hanging Cabinets on Metal Studs
Hanging cabinets on metal studs requires some different techniques compared to wood frame walls. Here are answers to some often asked questions about mounting cabinets to metal stud construction:
Can cabinets be installed directly on metal studs?
Yes, cabinets can be mounted directly to metal studs in some situations. Use self-tapping screws to attach cabinets to the studs, positioning screws every 12-16 inches along the back panel and side walls. Hollow wall anchors between studs can provide supplemental support. This works for lighter-weight cabinets. Extra blocking is recommended to better support heavier cabinets on metal studs.
What thickness of wood blocking should be used?
In most cases, 1×3, 2×3, or 2×4 lumber provides adequate blocking thickness between metal studs. Thicker 2x lumber provides more screw holding strength. Modify thickness according to cabinet load; for example, use 2×4 blocks under base cabinets carrying countertops or upper cabinets holding sinks.
How much weight can metal studs hold?
Metal stud capacity depends on gauge, size/spacing, and fastener type. Typical 25 gauge 3-5/8” metal studs can support up to 150 lbs per linear foot when attached at the top and bottom tracks. Higher weight capacity if secured mid-height as well. Compare metal vs. wood stud strength before loading.
Can I use drywall screws instead of self-tapping screws?
It’s not recommended. Drywall screws have very fine threads that are prone to stripping out of metal studs when used for hanging cabinets. Use good quality self-tapping screws with deeper, coarser threads designed for securing metal-to-metal. The screws will tap their own threads into the metal framing.
Should upper cabinets have a bottom cleat support?
Installing a horizontal wood cleat or ledger strip at the upper cabinet top is recommended to strengthen attachment. The cleat bridges two or more studs and allows screwing upward through the cabinet top for extra support. This helps transfer weight side-to-side off the metal studs.
What kind of hollow wall anchors work with metal studs?
Various types of hollow wall anchors can be used on metal studs, including: toggle bolts, molly bolts, EZ anchors, snap toggles, and nutserts. Toggle and molly anchors compress behind drywall when tightened. Nutserts thread into pre-drilled pilot holes in the metal studs for more direct load transfer.
Should lower cabinets be screwed to the floor too?
Yes, attaching a base cabinet into the floor adds stability. Using cabinet screws or nails through the cabinet “kickboard” into the floor framing helps prevent tipping forward when doors or drawers are opened. Construction adhesive caulk also helps anchor the bottom edge.
How do you attach a corner cabinet on a metal stud wall?
Use an L-bracket or triangle corner brace on inside walls to anchor the cabinet firmly. Attach it to adjacent walls with several molly bolts. This prevents rotation forces from pulling the cabinet off the corner when opening the cabinet door.
Can metal studs be damaged by driving screws too tight?
Over-tightening screws can potentially pucker or deform thin metal studs. Use self-tapping screws and drill pilot holes so screws install without excessive force. Tighten only until snug and flush with surface. Avoid excess torque that can twist or bend the metal.
Conclusion
Metal stud walls require careful preparation and installation methods when hanging cabinets. But with the right materials, reinforcement, and technique, it is certainly feasible to mount cabinets securely on metal framing. The key is using wood backing, proper screw selection, hollow wall anchors, and adequate screw spacing based on the manufacturer guidelines and expected cabinet loading.
