Drywall anchors aren't required for all wall-based fastening applications. If there's a stud directly behind the wall, for instance, you probably won't need to use them. Studs offer support for screws as well as the objects with which they are used. Of course, studs don't encompass the entire space of a given wall.
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.
Comments Section Drywall anchors are used when there is no stud behind the drywall. And only then. If you happen to have studs right where you need to drive the screws, then that's all you need.
Self-Drilling Wall Anchors
Overtightening them can damage the drywall and make the hold less secure. Self-drilling anchors are made of plastic, nylon or metal and come in different weight ratings.
You definitely want to hit a stud for heavy-duty loads like a TV bracket, a handrail, or a grab bar. Hollow wall anchors won't cut it. And for that, you first need to find the studs.

Installing an item in a stud behind drywall is the best option for strong support, so try to find studs first. Use anchors if studs aren't available.
An anchor can fail for several reasons, including the item you're hanging is too heavy, the hole for the anchor is too big, the screws going into the anchor are not the right size, and the drywall (or plaster) is old, damaged, and not stable enough.
Are wall anchors a permanent solution? Yes, wall anchors provide a long-lasting and permanent solution to basement wall instability. Once the wall anchors are installed and properly tightened, they effectively stabilize the walls and prevent further movement.
Threaded Drywall Anchors are the easiest to use as they are self-starting anchors that only need a Philip's head screwdriver to install. With their pointed tip, all you have to do is mark your wall where you want the anchor to be inserted and screw it in.
If you're using a threaded anchor, you must use a screwdriver or cordless driver to install the anchor into drywall. Attempting to hammer it in will damage the anchor and likely the wall. You can use a hammer to tap an unthreaded drywall anchor into a pilot hole as long as the pilot hole isn't too small.
A 1 1/2-inch (4d) nail driven in at a 45-degree upward angle can hold as much as 20 pounds. That's enough for a small to medium picture frame or a small wall light or planter.
Your first task in choosing an anchor is to have an understanding of three things: Your Boat - Your boats' size, weight and design characteristics affect what kind of anchor you will need to use. For instance, a 30 foot 10,000 pound houseboat needs a larger anchor than a 30 foot 6000 pound speedboat.
Whether you have a brick or uneven stone façade, or mounting a TV above a fireplace, mounting a TV can be tricky, but even more so when mounting a TV without studs. Even though drywall can support a TV up to 100 lbs., it's still brittle and the mount can require additional support.
Too few or too many: Follow the drywall manufacturer's instructions on the number of screws to use. Too few causes obvious issues, while too many means more mudding. Precision drives: Be careful how far you drive the screws if using a drill.
How much weight ceiling joists hold depends on their size and spacing and what they're made of. Wooden joists can support 50 to 100 pounds per square foot. Steel joists are more common in commercial buildings and can handle higher loads. Joists are spaced at regular intervals of 16 or 24 inches apart.
Now that the anchor is in place, you can screw in the item you want to hang. Make sure to use the right size screw for the anchor, and be careful not to overtighten the screw, as this can damage the anchor.
Foundation wall anchors consist of a threaded steel rod that is attached to the interior wall of the basement and anchored into the soil outside the home with a steel plate.
Can you remove and reuse drywall anchors? Whether you can reuse a drywall anchor or not depends on the type. Plastic expansion anchors and plastic self-drilling anchors, which expand once screwed into the wall, are single-use only.
Solution: The Manual Touch. The key to overcoming this is to skip the drill. Manual installation with a screwdriver allows for a gentler approach, ensuring the anchor threads engage properly with the drywall. If an anchor is already loose, gently remove it, patch the hole, and try again in a slightly different spot.
How it works: A molly bolt is a screw encased with metal that expands in a predrilled hole to support medium-weight items. Best for: high-use and mid-weight range items, like coat hooks, or with lightweight items in the ceiling, such as smoke detectors. Weight limit: 25 to 50 pounds.
Whether they be floating shelves or shelves with brackets—always, always use drywall anchors to mount them (if you're not screwing them into studs, that is).
Plastic screw anchors are some of the most common wall anchors, and they can perform well for many small jobs. Our expandable plastic screw anchors come in a variety of shapes, sizes and colors with larger options accepting larger screws to give you a little extra strength.
