Consider reinforcing the cabinets by attaching two screws into the stud. You can also anchor the cabinet to the drywall using French cleats or toggle screws, but only if you also secure it to a stud. Heavy cabinetry shouldn't be attached solely to drywall.
Hanging a cabinet without studs is a fairly DIY-friendly project, especially if you know how to use drywall anchors. Still, there is some skill involved in working with toggle anchors, as it's crucial to drill the correct-sized hole.
It is, as long as the hole isn't larger than the thickness of the stud . If you are hanging anything heavy on a studded wall, the fixings should be screwed into the studs.
Do Base Cabinets Get Attached to the Wall? Base cabinets should always be attached to the wall into the stud. This prevents them from accidentally shifting.
Use a stud finder to locate the wall studs. You'll want to screw the cabinets into them for secure installation. Mark the center of the studs with a pencil. Extend the lines up and down the wall with a carpenter's level, making sure you keep the lines plumb.
Installing upper cabinets starts with answering the question: How are kitchen cabinets attached to the wall? Typically, this is done by using a stud finder to locate studs and by drilling wood screws through drywall to attach the cabinet.
If you want to be safe, you can always cut out a section of drywall that will be completely hidden behind the cabinet, install a cross-stud inside the wall, screw the drywall piece back on for a spacer, then install the cabinet to the new cross-piece.
Drill pilot holes through the back of the cabinet and position your cabinet onto your located wall studs. Using wall screws of at least 1.5 inches or longer, screw the cabinet to the wall as it rests on the support. Put some shims in along the back of the cabinets if your cabinet is looking a bit wonky.
While drywall alone can hold about 1.6 pounds to 2 pounds per square foot, mounting an object to the stud with the proper hardware allows the drywall to support up to 100 pounds.
If you're going into metal studs, you could also damage wood screws since they aren't reinforced for use in metal. So, if you want to avoid having to break out the tools for drywall repair, it's best to use drywall screws for your projects.
The short answer is – it depends. Picture hooks do not necessarily require a stud in order to be functional and useful. The best rule of thumb to apply is that heavy items (think: mirror, heavy frame etc.) will require a hook that is anchored to a stud.
The holding strength of a screw in drywall is very close to nothing. Anyone can easily tear a screw out of drywall with just their bare fingers. If you need to mount something to a wall, you either need to hit a stud or you need to use a hollow wall anchor.
Once pilot holes are drilled, screw cabinets together using #8 x 2 ½” trim head screw. Wall cabinet should be secure to adjacent cabinet. Mount the cabinet to the wall stud with a 3-inch, #10 screw.
Kitchen cabinets approved by the Kitchen Cabinet Manufacturers Association are graded to hold up to 600 pounds of weight or 272.155 kilograms. Most manufacturers, however, have their own standards and guarantees, so it's probably more likely that you'll find cabinets that will hold up to 500 pounds of weight.
Drive screws into the back, just tight enough to hold it in place. Drill pilot holes with a countersink/taper bit through the face frames and connect the cabinets with #8 screws. If your wall is bowed, glue shims over the stud lines where you'll secure the mounting screws.
Things to consider when hanging kitchen units on stud walls
 In our example, a couple of timber battens as shown in the diagram to the right, is all that is needed. Some large units may have a further fixing rail nearer the lower edge of the unit.
Attach the cabinets to the studs with at least two screws in each mounting rail, while attaching the cabinets to each other with at least four drywall screws. Once all cabinets are securely in place, trim off the exposed shims with a utility knife.
Use a stud finder to locate wall studs. Mark stud locations on the wall. Confirm stud positions by drilling small pilot holes.
Studs are vertical 2 by 4 inch beams that support the frame of your home. You can find them behind your drywall, usually spaced 16 or 24 inches apart. Since studs are made of thick and sturdy wood or metal, they can securely hold screws better than wall materials like drywall.
By using wall anchors, toggle bolts, or specialized hardware, cabinets can be securely mounted without compromising the wall's integrity.
