Self-Drilling Plastic Drywall Anchor Weight Limit:
The most common type of plastic drywall anchors are the self-drill plastic anchors. These are used to fasten down walls with a minimum amount of effort. They have been around since the late 1980’s and they still work well today.
You may think that these plastic drywall anchors weigh a lot, but they really don’t. They weigh less than 1 pound per foot (0.4 kg/m2). However, they do not come cheap. A typical set of 5 will cost you $100 or more.
In addition to the weight limit, there are other factors that make them a good choice. First, they are easy to install and remove once installed. Second, they are very strong; however, it takes some skill to use one properly because you need to drill through several layers of drywall before you reach the hardwood flooring underneath your wall.
Finally, they are inexpensive. If you want to save money, then you could try out self-drilling drywall anchors instead of using nails.
What Are Self-Drilling Plastic Drywall Anchors?
These plastic drywall anchors are made up of two pieces which fit together like a puzzle piece. The first part is called the “base” and it consists of a thin sheet of plastic or even cardboard with holes drilled into it at regular intervals. The second part is called the “bolt” and it consists of a thick plastic cylinder at one end and several plastic flaps that stick out of the other end.
These two parts fit together so that the holes in the base align with the flaps on the bolt. To use it, you drill a hole using a power drill bit into the drywall. Next, remove the bolt (which has remained outside of the drywall).
Then, place the bolt back into the drywall so that it aligns with the hole you just drilled. Finally, screw in the bolt and repeat this process three more times until you reach the flooring.
Screws are then used to fasten the base to the floor or to hold the wall in place. These plastic drywall anchors have many benefits including being easy to use and inexpensive (even though they cost more than regular screws). They also allow you to mount your wall in hard to reach places.
How To Use Plastic Drywall Anchors
The plastic drywall anchors come in two pieces which are held together by a pair of metal wires. Before you use them, you must first remove these wires so that the two pieces can fit together more tightly. To do this, place the anchor over a hard surface such as wood or tile.
Then, start drilling the wires until they break. You can then remove the wire pieces through the holes in the base.
The next step is to drill the holes into the drywall. Use a power drill and make sure that you go slowly so that the bit doesn’t snap off inside the wall. Keep drilling until the bit has gone through the entire wall.
After this, remove the bit from the power drill and then place the bolt into one of the bolt holes. Next, push it in so that it goes all the way through. At this point, you should be able to see the bolt head on the other side of the wall.
While holding the bolt in place with one hand, grab the base with your other hand and place it over the bolt so that the holes line up. Next, push down on it so that the flaps go through the wall. There may be a little resistance but keep pushing until it is all the way through.
Once this is done, you should be able to see the flaps on the other side.
At this point, your plastic drywall anchors are ready for use. The bolt and base can be used to support heavy objects such as shelves or even concrete blocks. The flaps on the bolt side can be used to screw into the wall or even a wooden beam.
You can also use the bolt side to secure the base to a wooden beam.
Once your structure is in place, it is a good idea to screw it into the wall as well as the floor or beam. This will prevent injury in the event that someone bumps into it.
You can then mount your shelves or other items onto the wall using screws, nails or even glue.
How To Remove Plastic Drywall Anchors
If you no longer need the item that you have mounted, it is important that you remove it. You can do this by drilling out the drywall anchors and removing them.
Whether you buy other plastic drywall anchors or decide to go with another type of fastener, you’ll need to know how to get rid of your old ones so that you don’t get any accidents in the future.
First, find the studs in the wall using a stud finder. Then, use a drill to make pilot holes for the new anchors into these studs. Next, remove the old plastic anchors by drilling out the center.
You can then pull them out and repeat this process until all of them are gone.
Once this is done, you should have no problems putting up your new shelves or other items.
Where To Buy Plastic Drywall Anchors
Plastic drywall anchors can be bought in most hardware and home improvement stores. They are usually quite cheap and you’ll definitely want to get a few extra. A bag of 100 costs less than $10 and should be more than enough to support all of your shelves and other items.
You can also find them online if you don’t have a store nearby or perhaps you’d rather have them shipped to your door.

How To Use Regular Drywall Anchors Instead Of The Plastic Ones
The regular drywall anchors can be used in exactly the same way.
If you already have a bunch of these in your toolbox, then you are already set.
They work in exactly the same way as the plastic anchors except that you obviously can’t use a power drill to drive them in as easily. You also need to countersink them into the wall so that the head is flush with the wall.
If you have to drill a pilot hole, make it about half the diameter of the screw. This will ensure that the head sinks into the wall enough to be flush.
These work great for hanging lightweight objects such as pictures and lightweight shelves but obviously aren’t strong enough to support heavier items.
You can also buy these in a stainless steel version. These cost a little more but they are corrosion resistant. You’ll mainly find these in the DIY and Hardware stores.
Frequently Asked Questions
Here are answers to some of the most commonly asked questions about plastic drywall anchors.
Can I use a regular metal screw in a plastic anchor?
A. No, this is not a good idea as they will easily strip, especially if you are using a power drill.
Will the plastic anchors work in hardboard and particle board as well as drywall?
A. No, they will not work in hardboard or particle board as they are not strong enough to support anything being hung from them.
Can I use a drill to put the plastic anchors in?
A. Yes, you can but it is best not to. If you do this, only use a smaller power drill bit such as a 1/32″ or 1/64″. Larger sizes will easily strip the plastic.
