How to Hang Cabinets with Metal Studs
Hanging cabinets on metal studs requires some special considerations compared to wood studs. Metal does not hold screws as well, so additional steps must be taken to ensure cabinets mount securely. With the right preparation and materials, you can achieve a sturdy installation that will support your cabinets for years to come.
Choosing Appropriate Hardware
The first step is using hardware specifically designed for metal studs. Self-tapping screws are not sufficient, as they can strip out of the thin gauge metal. Here are some good options:
- Toggle bolts – These provide a sturdy hold by going through the hole in the stud and then opening up on the other side. Tightening the bolt causes the metal wings to flatten on the back of the stud.
- Metal screws – Special screws are made to grip and hold in metal studs. Use ones at least 1 inch long and make sure they are rated for metal.
- Hollow wall anchors – You can insert anchors into the stud that expand when a screw is inserted, creating a tight hold. Opt for heavy duty ones rated for maximum weight.
Required Tools
In addition to appropriate screws/bolts, you will need:
- Electric drill and drill bits
- Stud finder
- Level
- Hammer (if using hollow wall anchors)
Locating Studs
Metal studs are often precisely spaced 16 inches or 24 inches apart. But it’s important to still locate them using a stud finder to identify exact center points. Driving screws even 1/2 inch off center can cause them to miss or strip out of the stud.
Follow stud finder instructions to slowly scan the wall and mark centers with a pencil. Check multiple spots up and down to ensure consistency.
Where to Install Screws/Bolts
Ideally screws or bolts should go into the studs where cabinet frames will sit. If the stud layout doesn’t align, here are good options:
- Use drywall anchors – For lighter cabinets, you can use hollow drywall anchors between studs. Look for heavy duty toggle or molly bolt types rated for weight of cabinet.
- Add horizontal bracing – Secure a long piece of wood horizontally to two or more studs. Position it where cabinet frame will be and screw into the wood.
- Shim out from stud – Secure a scrap piece of wood to the stud, then shim out horizontally with more scrap to create a mounting surface for cabinet screws.
Drilling Pilot Holes
It’s crucial to drill pilot holes in the stud before driving screws or bolts. This prevents stripping out the hole or cracking the stud metal. Use a bit slightly smaller than the screw diameter. A good guideline is 70% of the screw width for soft metals like aluminum or 30-40% for hardened steel.
Drill holes centered at your desired height marks. Hold the drill level and straight to perpendicular. Let the bit do the work, don’t force it.
Driving Screws and Bolts
With pilot holes drilled, carefully drive screws or install toggle bolts/anchors per product directions.
For screws, use the right driver bit and a variable speed drill. Set the speed low and increase gradually. Let the screw pull itself into the metal; forcing can damage the hardware or stud.
Follow any specific instructions your cabinet manufacturer provides for installation. They may have recommendations on fastener type, locations, or load ratings.
Tips for Success
Follow these tips to ensure your cabinet installation onto metal studs goes smoothly:
- Use screws rated and designed for metal – at least 1 inch long. Self-tapping varieties won’t hold well.
- Drill proper pilot holes to prevent stripping out or cracking metal when driving screws.
- Distribute screws/bolts evenly to disperse weight. Group 3-4 per stud where cabinets will mount.
- Shim out securely from studs if needed to create mounting points aligned with cabinet frames.
- Consider adding horizontal blocking between studs for more screw/bolt locations if necessary for heavy cabinets.
- Take care not to overtighten screws or bolts. Tightening too much can damage the hardware or pull the metal stud inward.
With the right screws, drilling practices, and preparation, you can gain a rock-solid install for hanging cabinets on metal stud walls. Take the time to do it right, and your cabinets will enjoy years of durable function.
FAQs About Hanging Cabinets with Metal Studs
What type of screw is best for metal studs?
Look for screws specifically designed for metal, at least 1 inch long, such as self-drilling drywall screws or Spax PowerLags. Avoid using standard coarse-thread wood screws.
Should I pre-drill holes for screws in metal studs?
Yes, it’s highly recommended to pre-drill clearance holes before driving screws into metal studs. This prevents stripping out the holes or cracking thin metal when you screw them in.
Where should I place screws on the metal studs?
Aim to position screws centered in the stud where cabinet frames will sit. If needed, shim out or add blocking to create mounting points. Distribute screws evenly spaced vertically.
How do I use toggle bolts on metal studs?
Drill a clearance hole through the stud, then insert the toggle and tighten the bolt to flatten the wings on the back side of the stud. This creates a solid mounting point for hanging cabinets.
What size drill bit do I use for pilot holes in metal?
For soft metals like aluminum, use a bit 70% the diameter of the screw. For hardened steel, use 30-40% the screw diameter. Let the drill do the work, don’t force it.
Can I hang cabinets directly onto the drywall instead of studs?
No, you should always mount cabinets directly onto studs for strength and stability. For metal stud walls, use special screws or bolts designed to grip metal.
Conclusion
Installing cabinets on metal stud walls is doable with the right preparation and hardware. Be sure to use screws or anchors specifically designed for metal that will hold well. Drilling proper pilot holes prevents issues like stripped screws or cracked studs. Locate studs precisely, and distribute screws evenly for maximum strength. With careful planning and the right materials, you can achieve a solid metal stud cabinet mount that will serve your storage needs for many years.
