You often see these in different parts of the house, but typically, you will most likely find these in the kitchen. Cabinets, otherwise known as cupboards, are storage furniture usually made with wood that are intended to store or display items. 

For many homes, cabinets are already pre-installed when you buy or move into the house. However, throughout the years, these cabinets will soon wear down or you're probably looking to update the look of your space. A lot of homeowners by this time would look into installing their own cabinets for their rooms.

Most cabinet manufacturers have everything you will need prior to installing a cabinet. While it is very convenient, a good rule of thumb is to use sturdier fasteners instead of the manufacturer's screws. This will give your cabinets a stronger hold on your walls.

To install cabinets on your walls, you should prepare at least eight screws before installation. For every foot of cabinet you will need about four screws to secure them to the studs behind the walls.

The more cabinets you would like to install to form your storage unit, the more screws you will need. It's always a good idea to stock up on the screws that you will need, just in case you drop some or you need more for extra security during installation.

Do not use drywall screws or other non-shear strength screws because these will surely give up under the weight of the cabinets. Using screws like these can most likely cause an accident or damage your cabinets.

There is no single generic screw that you can use when installing cabinets. Keep in mind that there are different materials that come into play during installation, so we will talk about the screws that are suitable to use for your cabinets.

Other Tools For Cabinet Installation

Aside from cabinet screws, there are some tools that can help you install your cabinets perfectly. These tools are meant to make installation easier for you.

Cabinet Jacks

Ideally, installing cabinets should be done with an extra pair of hands (or more) but this is not a luxury everyone can have. This is where cabinet jacks come in. A cabinet jack holds up cabinets in place while they are being shimmied, clamped into place, or when they are being screwed together.

Cabinets need to be screwed directly to a stud, so you won't be able to do this job without a stud finder. These things are pretty straightforward—you use these finders to look for studs behind the wall where you can install your cabinets.

How Much Weight Can Cabinets Hold?

Cabinets are known to be very sturdy and can hold a lot of weight even with their small size. In the kitchen alone, cabinets are known to hold glassware, dinnerware, serving ware, and cookware, among other things.

According to the Kitchen Cabinet Manufacturers Association (KCMA), installed kitchen cabinets should be able to hold weight of up to 500 pounds for the entire overhead unit. It might sound a lot, but with the number of items that are regularly piled in throughout the years, the load the cabinet can hold should be quite significant. 

Whenever you buy kitchen cabinets, make sure to check with your manufacturer's weight limits. This will ensure that you will be able to secure and you can add additional support to your cabinets if the need arises.

If you are going to have cabinets custom-made, make sure to talk to your carpenter about the load it can handle. Pick high-quality materials, fasteners, studs, and other necessary items to make sure that your cabinets will have a strong, solid foundation to carry heavy loads.
