5 Types of Dynabolt and Their Uses


Dynabolts are one of the most commonly used and versatile anchor bolts in the construction industry. Whether you’re building a new structure, adding to an existing one, or just securing something to concrete or masonry, there’s a Dynabolt to meet your needs. This expert guide will deeply dive into the different types of Dynabolts available and their specific uses.

Types of Dynabolt and Their Uses

Sleeve Anchors:

One of the most popular types of Dynabolts, sleeve anchors are used for light to medium duty applications. They are available in different sizes and lengths, making them ideal for various applications, such as attaching electrical boxes, light fixtures, and pipes. Sleeve anchors expand when the nut is tightened, creating a tight fit between the fixture and the concrete or masonry.

Wedge Anchors:

Wedge anchors work similarly to sleeve anchors but offer a higher load capacity, making them ideal for heavy-duty applications. They attach heavy equipment or machinery to concrete floors, walls or ceilings. When the nut is tightened, the wedge is drawn up inside the sleeve, creating a secure and tight fit.

Through Bolts:

Through bolts are used when you need to fasten something to the concrete and have access to both sides of the structure. They are commonly used to construct bridges, towers, and other large structures. The through bolt is inserted through a hole in the concrete and tightened from the opposite end, securing the fixture.

Strike Anchors:

Strike anchors are used for medium to heavy-duty applications requiring quick installation. They can be quickly installed and provide high load capacities, making them ideal for securing structural supports, railings, and tie-downs.

Drop-In Anchors:

Drop-in anchors are used when you need a smooth, flush finish and don’t want anything protruding from the surface. They are high strength and work by inserting into a pre-drilled hole and then using a special tool to “set” the anchor into place. Drop-in anchors are typically used for securing handrails, guardrails, and other safety equipment.


Choosing the right Dynabolt is essential to ensuring a secure and stable fixture, regardless of the application. Understanding the different types of Dynabolts available and their specific uses can help you select the right anchor bolt for your needs. Consider the load capacity, the type of fixture you’re attaching, and the surface you’re securing when choosing a Dynabolt to ensure reliable and long-lasting results. When in doubt, consult with an expert to ensure the safety and durability of your construction projects.
