| Anchors by McMaster-Carr | Varies | Varies | General purpose, customizable solutions |
Understanding Stud Anchors
Stud anchors are typically pre-assembled fasteners that consist of a bolt body and an expander end plug. They are designed for use in concrete and require a pre-drilled hole that matches the diameter of the anchor. Upon hammer driving the anchor into the hole, the expander plug activates, causing the anchor to expand and secure itself within the concrete. This simple yet effective design allows for a strong hold without the need for additional torque, making it a popular choice among contractors.
Types of Stud Anchors
Power-Stud®+ SD2
The Power-Stud®+ SD2, available at anchors.dewalt.com, is known for its high performance and reliability. It features a wedge expansion mechanism that provides excellent holding strength in concrete applications. This anchor is ideal for general construction projects, where robust anchoring is necessary.
Power-Stud® Stainless Steel Anchor
Also from DEWALT, this stainless steel version is designed for environments where corrosion resistance is essential. It maintains the same expansion mechanism as the SD2 but offers enhanced durability for outdoor and marine applications.
Red Head Stud Anchors
As described on www.fastenermart.com, Red Head stud anchors are designed with a pre-assembled bolt body and expander end plug. Their unique design allows for easier installation, particularly in leveling and jacking applications.
Applications of Stud Anchors
Stud anchors are versatile and can be used in many applications, including:
- Concrete Anchoring: Used in commercial and residential construction for securing heavy fixtures.
- Leveling and Jacking: Ideal for adjusting the height of structures.
- Marine and Outdoor Applications: Stainless steel options provide resistance against harsh weather conditions.
Selecting the Right Stud Anchor
Choosing the right stud anchor involves considering several factors:
Material
The material of the stud anchor is critical. Stainless steel offers corrosion resistance, making it suitable for outdoor applications, while carbon steel is often used for standard concrete anchoring.
Load Requirements
Understanding the load requirements of your project is essential. Different anchors have varying load capacities, so selecting one that meets or exceeds your needs is crucial for safety.
Installation Environment
Consider the environmental conditions where the anchor will be used. For instance, stainless steel anchors are preferable in coastal areas due to their resistance to saltwater corrosion.
Technical Features of Stud Anchors
| Anchor Type | Diameter Range | Load Capacity | Installation Method | Corrosion Resistance |
|---|---|---|---|---|
| Power-Stud®+ SD2 | 3/16″ to 1/2″ | Up to 1,200 lbs | Hammer-driven | Moderate |
| Power-Stud® Stainless Steel Anchor | 3/16″ to 1/2″ | Up to 1,500 lbs | Hammer-driven | High |
| Red Head Stud Anchors | 1/4″ to 1″ | Up to 2,000 lbs | Hammer-driven | Moderate |
| Concrete Stud Anchors | 1/4″ to 1″ | Up to 2,500 lbs | Mechanical | Low |
| Stainless Steel Stud Anchors | 1/4″ to 1″ | Up to 2,000 lbs | Hammer-driven | Very High |

FAQ
What is a stud anchor?
A stud anchor is a type of fastener designed for anchoring materials to concrete. It typically consists of a bolt body and an expander plug that, when driven into a pre-drilled hole, expands to create a secure hold.
What materials are stud anchors made from?
Stud anchors are generally made from steel, stainless steel, or carbon steel. The choice of material often depends on the application and environmental conditions.
How do you install a stud anchor?
Installation involves drilling a hole in the concrete that matches the anchor’s diameter, inserting the anchor, and then hammering it in to activate the expansion mechanism.
What are the applications of stud anchors?
Stud anchors can be used for concrete anchoring, leveling and jacking applications, and in environments requiring corrosion resistance, such as marine settings.
Can stud anchors be removed once installed?
While they can be removed, doing so may damage the anchor or the surrounding concrete. It’s best to consider them a permanent solution unless specifically designed for reusability.
What is the load capacity of stud anchors?
Load capacity varies by type and size. For example, some stud anchors can support loads ranging from 1,200 lbs to 2,500 lbs or more, depending on their design and material.
Are there different installation methods for stud anchors?
Most stud anchors are hammer-driven, but some may utilize mechanical installation methods, depending on their design and application.
How do I choose the right stud anchor for my project?
Consider the material, load requirements, and environmental conditions before selecting a stud anchor. Ensure that the anchor meets or exceeds your project’s needs.
Where can I find more information about stud anchors?
You can find detailed information on stud anchors at websites like anchors.dewalt.com, www.concretefasteners.com, and www.fastenermart.com.
Do stud anchors require special tools for installation?
Typically, you will need a drill for creating the hole and a hammer for driving in the anchor. However, specific anchors may come with unique installation requirements.
