Typically, a metal hollow wall anchor can support up to about 50 lbs. in a 1/2-inch drywall. You can see all of our heavy-duty hollow wall anchors' sizes in the chart below.
Hollow Wall Anchors Features:
Medium duty for typical loads of 10kg for 4mm, 15kg for 5mm and 6mm fixings. Use with our auto-collapse hollow wall anchor tool for rapid repetitive fixing or simply screw in with a power or hand screwdriver to expand the anchor.
Threaded drywall anchors are suitable for objects weighing up to 25 pounds and are ideal for use on drywall. Hollow-wall anchors can hold up to 30 pounds per pair on plaster, paneling and other hollow walls.
This way, the hollow wall anchor make it possible to fasten heavier objects to plasterboard. With such anchors, one square meter of (properly installed) plasterboard comprising a single wallboard can support a weight of 15 kg.
Typically, drywall can support between 5 and 10 pounds with a simple nail, but anything heavier requires additional support. For heavier objects, using drywall anchors or finding a stud to screw into will provide a much more secure hold.
The type of fastener you use can also influence the amount of weight the drywall can hold. If you opt for picture hangers or simple nails, then stick to objects that are less than 20 pounds. Flat mounted hooks and anchors may be able to hold up to 50 pounds, while drywall screws can hold about 20 pounds of weight.
If your ceiling is supported with joists, attach the heavy object directly to the ceiling joist to provide extra support. If your ceiling is hollow, you can use toggle bolts to support your heavy object instead.

Mounting a TV with drywall anchors or bolts is a great option if you can't drill into a stud. You'll need to use a hollow wall anchor that looks similar to a regular screw, with a butterfly toggle at the end. Once they're placed in the wall, they'll attach to the back.
Choosing Hollow Wall and Drywall Anchors
Determining the correct wall anchor to use for your project depends on the wall's material and, more importantly, the weight of the item being hung. Ensure the item's weight does not exceed the anchor's weight limit. Some anchors may require special installation tools.
Holding power is formulated based on environmental factors, like wind speed. As a general rule, a holding power of 90 pounds is sufficient for safely anchoring a 20' boat in winds up to 20 mph. For the same wind speed a holding power of 125 pounds is adequate for a 25' boat.
Hole Diameters
M6 - 10mm hole.
Drywall anchors can hold anywhere from 10 to 200 pounds, depending on the type and installation. Always choose an anchor rated for more than the weight of the item you are mounting.
Wedge anchors are one of the strongest anchors available. They come in nine different diameters and several different lengths. The larger the anchor, the more holding power it has. They also come in several different materials, so you can use them in areas with or without the possibility of corrosion.
If you're hanging an object up to 25 pounds, use an anchor to securely fasten the object or picture frame to the wall without damaging the soft drywall itself. A threaded anchor will come with a small plug that you can screw or hammer into the wall.
not always stated in the vehicle or car seat owner's manual. If the manufacturer offers no weight limit, do not use lower anchors or the tether anchor if child + car seat weight is more than 65 pounds.
One square meter of double plasterboard can support 25 kg, and triple wallboard can support 35 kg. The studs reset the weight that the wall can cope with. For example, one square meter to the left of a stud can support 15 kg, and one square meter to the right of the stud can support another 15 kg.
Hollow wall anchors
If you're fixing into plasterboard that hasn't been skimmed you'll need a setting tool, but in other instances that may not be required.
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.
Threaded Drywall Anchors:
While they don't include the attaching screw, these are also good for ceiling and overhead hanging. These are secure, and are labeled as self-drilling, which means you don't need to pre-drill a hole to install them, unlike every other type of drywall anchor.
