What Is the Strongest Masonry Anchor
The strongest masonry anchor is the wedge anchor.
Wedge anchors are known for their exceptional hold strength.
Did You Know?
1. The strongest masonry anchor available is the wedge anchor, which can hold more than 10,000 pounds of force depending on the size and material used.
2. Carbon fiber strips or plates can also be used as an anchor reinforcement for masonry, providing an incredibly strong yet lightweight solution.
3. In ancient Egyptian construction, the strongest masonry anchor used was the dowel bar anchor, which consisted of metal bars inserted into the stone blocks to increase stability.
4. A lesser-known and innovative masonry anchor is the undercut anchor, which uses a combination of adhesive and mechanical anchoring to provide exceptional strength.
5. For seismic-resistant structures, one of the strongest masonry anchors employed is the seismic hook anchor, designed to withstand intense lateral forces and keep the masonry securely attached to the building frame.
Drop In Anchors
Drop-in anchors are a popular choice for heavy-duty masonry applications due to their exceptional strength and reliability. These anchors consist of a threaded steel cone-shaped body with a flanged top and a lip at the bottom. They are designed to be set into pre-drilled holes in the concrete or masonry using a special tool, known as a setting tool.
Once the drop-in anchor is inserted into the hole, a hammer is used to strike the setting tool, causing the anchor to expand and grip the surrounding material tightly. The result is a secure and strong anchor that can withstand heavy loads.
Drop-in anchors are commonly used in applications such as securing structural steel connections, installing machinery, or anchoring heavy equipment.
Lag Shield Anchors
- Lag shield anchors, also known as expansion anchors, are a reliable choice for heavy-duty masonry applications. These anchors consist of a tapered cone-shaped outer shield made of durable materials like zinc or stainless steel.
- Lag shield anchors are specifically designed to provide a secure hold in materials such as concrete, brick, or stone.
- The installation process for lag shield anchors involves drilling a hole into the masonry and then inserting the anchor.
- As a lag screw is tightened into the anchor, the anchor expands, ensuring a strong and stable hold.
- These anchors are commonly used for various applications, including securing timber or metal objects, attaching handrails or guardrails, and mounting heavy fixtures or equipment.
Masonry Concrete Screws (Tapcons)
Masonry concrete screws, commonly referred to as Tapcons, are a type of fastener specifically designed for anchoring into masonry, such as concrete or brick. These screws feature a unique thread design that provides exceptional holding power and vibration resistance.
The installation process for Tapcons involves drilling a hole into the masonry using a carbide masonry bit. Once the hole is drilled, the Tapcon is inserted and then tightened using a drill or impact driver. As the screw is driven into the hole, its thread engages and cuts into the masonry, creating a secure bond.
Tapcons are known for their strength and versatility, making them suitable for a wide range of heavy-duty applications, such as attaching electrical boxes, mounting fixtures, or securing doors and windows in masonry openings.
Sammys Hanging Anchors
Sammys Hanging Anchors are a unique type of masonry anchor specifically designed for overhead applications, such as suspending pipes, cable trays, or ductwork. These anchors are ideal for projects that require secure and stable support for heavy loads overhead.
These anchors consist of a rod with a threaded end and a pre-assembled head, which includes a hole for attaching the hanging system.
To install Sammys Hanging Anchors, a hole is drilled through the material being anchored (such as concrete or steel) and then the anchor rod is inserted. As the rod is turned, a sharp piercing point on the anchor’s head cuts into the material, providing a secure hold.
Key features of Sammys Hanging Anchors:
- Specifically designed for overhead applications
- Consist of a threaded rod and a pre-assembled head
- Easy installation process through drilling and insertion of the rod
- Secure hold provided by the sharp piercing point on the anchor’s head
Benefits of using Sammys Hanging Anchors:
- Support heavy loads overhead with minimal effort
- Ensure maximum stability for suspended items
- Suitable for commercial and industrial applications
“Sammys Hanging Anchors offer a reliable solution for securely suspending pipes, cable trays, or ductwork overhead. Their unique design and ease of installation make them an ideal choice for projects that require stable support for heavy loads.”
Hammer Driven Pin Anchor
Hammer driven pin anchors, also known as nail-in anchors, are a straightforward and reliable masonry anchoring solution. These anchors comprise a stainless steel or zinc-coated pin with a knurled or grooved shank for enhanced grip.
Installing a hammer driven pin anchor involves first aligning the anchor with the pre-drilled hole in the masonry and then striking the head of the anchor with a hammer until it is flush with the surface. As the pin is driven into the hole, it expands, creating a secure hold.
Hammer driven pin anchors are commonly used for light to medium-duty applications that require a strong anchor, such as installing electrical boxes, small shelving units, or suspended light fixtures. While not as robust as some other anchors on this list, hammer driven pin anchors still provide a reliable and sturdy solution for many masonry projects.

Frequently Asked Questions
What is the strongest concrete anchor type?
When it comes to concrete anchoring, one of the strongest types is the epoxy anchor. Epoxy anchors offer exceptional hold strength due to the epoxy resin that is injected into the drilled hole before inserting the anchor. The epoxy hardens and creates a strong bond with the concrete, providing superior stability and load-bearing capacity. This anchor type is particularly reliable in heavy-duty applications or when dealing with high tension or sheer loads.
Another highly robust concrete anchor type is the mechanical anchor. These anchors utilize mechanical expansion to grip the concrete securely. The installation involves expanding the anchor within the hole, creating a tight fit and substantial resistance against forces. Mechanical anchors are known for their high load capacity and are commonly used in critical applications such as high-rise buildings or infrastructure projects where structural integrity is paramount.
What is the strongest brick wall anchor?
The strongest brick wall anchor is the shield anchor, commonly known as “rag bolts.” These anchors are renowned for their exceptional strength and stability, making them the superior choice among masonry fixings. Designed to encapsulate and reinforce bolts, shield anchors significantly increase the overall surface area and thickness, providing unparalleled support and durability. With their exceptional design, shield anchors stand out as the most robust wall anchors available in the market.
What is the strongest masonry fixing?
The strongest masonry fixing is the expanding masonry bolt. This highly durable fixing is designed specifically for attaching heavy items, such as fence posts, to masonry walls. By screwing a bolt into a metal or plastic segmented shield and placing it into a drilled hole, the expansion of the segments as the bolt is tightened allows for a secure grip on the sides of the hole, ensuring maximum strength and stability. Whether it’s for industrial or residential applications, the expanding masonry bolt is the go-to solution for robust masonry fixings.
What is the best anchor for brick?
The wedge anchor is widely regarded as the best anchor for brick due to its reliable and strong holding power. It is specifically designed to expand over a larger surface area, complementing the properties of brick walls. This expansion anchor ensures a secure attachment and provides consistent holding values, making it a preferred choice for anchoring bricks in various applications. With its efficient design and superior stability, the wedge anchor is an ideal solution for any project requiring a dependable and durable anchor for brick walls.
Another noteworthy anchor option for brick is the hammer drive anchor. This type of anchor uses a hammer to drive it into the brick, creating a tight and secure hold. With its simplicity and ease of installation, the hammer drive anchor is a popular choice for smaller-scale projects or situations where limited load-bearing capacity is required. Although it may not possess the same expansion capabilities as sleeve or wedge anchors, the hammer drive anchor provides a reliable solution for anchoring bricks in applications that do not demand heavy-duty support.
