What To Know Before Buying Drywall Anchors

When purchasing drywall anchors, consider factors such as weight limit, screw size, and material to ensure you buy the best product for your needs. Read our guide below to learn more about the most important considerations.

Weight Limit

A drywall anchor’s weight limit determines how heavy of an item you can hang from it. If you’re hanging a small photograph or towel holder, the weight limit will matter less than if you’re hanging a shelving unit or large mirror. Ensure you know the weight of the item you’d like to hang before purchasing anchors. It’s particularly important to be aware of your item’s weight if it’s fragile, as using too small of an anchor could cause it to fall and break.

Screw Size

Many drywall anchors come in kits that include the necessary screws. If you buy a drywall anchor set that does not come with screws, carefully check that you have the right size screws for the anchors, and purchase them if you don’t. The correct screw size is often listed on the package.

Material

Drywall anchors are typically either metal or plastic. Metal anchors are stronger, more durable, and better for holding large items. Plastic anchors are less expensive and often come in larger packs. They are better suited for hanging small items, such as small artwork and pictures.

Types of Drywall Anchors

There are several different types of drywall anchors, and each has its own advantages and disadvantages. Here are the main drywall anchor types you will encounter and what their common functions are.

Toggle Bolt Anchors

Toggle bolt anchors, also called industrial bolt anchors, are ideal for heavy-duty use. They are available in both plastic and metal and have a butterfly-like shape with wings that lock against drywall. While durable and designed for large items, they can sometimes be challenging to install because they require drilling a large hole.

Expansion Anchors

These anchors expand to create a tight bond with drywall when installed. They are usually made of plastic and are best suited for lightweight items.

Self-Drilling

Self-drilling anchors, also called threaded anchors, can easily cut through walls and require only a screwdriver for installation. They’re typically made from hard nylon or metal and are designed to hold heavy items.

Molly Bolts

Molly bolts, also called “mollies,” are screws encased with metal that expand inside predrilled holes. They are best suited for medium-sized items and are removable if necessary, which is a rarity among drywall anchors.

Steel-Hollow Wall Anchors

Steel-hollow anchors are sturdy and can typically hold at least 40 to 50 pounds per anchor. They feature metal casing with a screw and a load-distribution washer. When inserted, they expand and tightly hold onto drywall for extra stability.

What Can You Hang With Drywall Anchors?

There are certain items you simply can’t hang from a nail or screw, especially on drywall ceilings and walls. With drywall anchors, you can securely hang heavy objects and ensure they stay in place. Here are some things you can hang with drywall anchors: 

  • Artwork
  • Bookshelves 
  • Clocks
  • Light fixtures
  • Memorabilia 
  • Mirrors
  • Paper towel holders
  • Picture frames
  • Shelving 
  • Towel racks
  • TV mounts
  • Wall-mount cabinets

FAQ About Drywall Anchors

When do you not need a drywall anchor?

If you can locate a wall stud using a stud finder, you won’t need to use a drywall anchor, as nails driven into studs can hold a large amount of weight. 

How much weight can drywall anchors hold?

The weight drywall anchors can hold varies significantly based on the type of anchor and the specific model. Typically, smaller drywall anchors can hold anywhere from 10 to 50 pounds, while more heavy-duty models can hold up to 200 pounds. 

How do you install drywall anchors?

You can install self-drilling anchors without using a power drill by screwing them into drywall with a screwdriver. For most drywall anchors, however, you should drill a pilot hole in the wall using a drill bit that’s smaller than the anchor’s width. Then, place the anchor in the pilot hole and lightly tap it with a rubber mallet until it is fully inserted. Avoid hammering in drywall anchors, as it could break the drywall and create too large of a hole.

Are drywall anchors reusable?

Some drywall anchors are designed to be reused, but it’s important to check the individual product description first if you plan on using an anchor more than once. Most toggle bolts, for example, are not reusable. Reusable metal or plastic anchors still need to be carefully removed. If the anchor is broken once you remove it from the wall, it can’t be reused.

7 Basics to Quickly Understand Self-drilling Anchor System (SDA/IBO)

Self-drilling anchors are first applied in tunnel construction, i.e., NATM.


But in recent years, this innovation reinforcing material is introduced to civil engineering, such like micropiling and soil nailing, and underground construction.

Here are 7 tips help you understand SDA better.

What is self-drilling anchor (SDA, IBO)?

Definition:

Self-drilling anchor is a type of hollow steel bar that is used in the construction industry for supporting structures. 

It is made of steel and has a hollow core that allows for grouting and drilling at the same time.


What is self-drilling anchor system?

 The self-drilling anchor system can be used in a variety of geotechnical applications, such as foundations, slope stabilization, and retaining walls.

 It consists of a continuously threaded, hollow bar that can be drilled into the ground and filled with cement grout to provide reinforcement and stability to a  structure.

 The SDA system is designed to be easy to install, with minimal disturbance to the surrounding terrain, and is often used in difficult soil conditions where traditional anchoring methods may not be suitable.

 

 What are the components of a whole SDA system?

The components of a whole Self Drilling Anchor (SDA/IBO) system typically include:

Hollow Anchor Bars: These are self-drilling, hollow steel bars that serve as the reinforcement and grout conduit for the micropile.

Drill Bit: This is used to drill the hole for the micropile.

Injection Pump: This is used to inject grout into the hollow bar during installation.

Plate: This is typically used to provide a load transfer between the micropile and the structure being supported.


Nut: This is used to secure the hollow bars together or to provide load transfer from the micropile to the structure being supported. Rayon Rock offers hex nut, spherical dome nut and collar nut.

Coupler: This is used to connect two hollow bars together to extend the length of the micropile.

Overall, the SDA system is a micropile system with a fully threaded, hollow, self-drilling anchor that can provide immediate axial loading capacity. The system is typically used for slope stabilization, foundation support, and retaining walls, among other applications.

What is the duration of the SDA system?

The Self drilling anchor system is a construction technique that involves the use of hollow steel bars to create micropiles for slope stabilization, foundation support, and retaining walls, among other applications.

As a construction technique, the duration of the SDA system depends on several factors, including the specific application, site conditions, and environmental factors.

Typically, the installation and construction process for an SDA system can take several days to a few weeks, depending on the complexity of the projec.

 However, once the system is installed and in place, its lifespan can vary greatly depending on the aforementioned factors.

 The galvanized coating applied to the hollow bars can further extend their lifespan.

 Please note: All system components including the bearing parts (nut, plate) and coupler need galvanization.

What are the main suppliers of SDA/IBO systems?

Many construction contractors use this solution in their projects.

Such as Con-Tech Systems (CTS), which is a company that offers Titan IBO hollow bar anchors, soil nails, and micropiles. They are also the manufacturer of the CTS/Titan IBO system.

Additionally, other companies, such as Minova /MAI and DYWI/DSI, supply self-drilling anchor systems.

Who manufacture self-drilling anchor materials?

China is the biggest original manufacturing country of these products.

Many international brands have their OEM for the whole industry chain.

And there is a solid choice if you want to purchase accessories: Rayon Rock. You can get the highest quality nuts and couplers, which have been qualified by the strictest clients in this industry.

Are your products matchable to CTS/DYWI/ systems?

All Rayon products have exact standards to accompany the specific system.

Such as the thread, we follow the international ISO10208 standard for the normal R25, R32, and R38. For other series of SDA/IBO hollow bars, we offer accessories in customized standards.

All products have passed the trial of installation. And free samples can be provided for your test.
