Difference Between Anchor Bolt and Expansion Bolt

Anchor Bolt vs Expansion Bolt

If you’ve ever done any home improvement or construction work, you’ve probably heard of anchor bolts and expansion bolts. But do you really know the differences between them? For those who aren’t familiar with construction terminology, it can be difficult to understand when to use an anchor bolt versus an expansion bolt. In this blog post, we will discuss the differences between these two types of bolts so that you can make an informed decision when it comes to your project.

Anchor Bolt

Anchor bolts are used in concrete foundations and masonry walls to secure pieces of wood, steel, or other materials together. The anchor bolts are embedded into the concrete, and then a nut is used to fasten them together. Anchor bolts come in many sizes and shapes depending on their purpose and application. Most commonly, they have a hexagonal head with a washer at one end and a threaded section at the other end.

Expansion Bolt

Expansion bolts are similar to anchor bolts, but they expand when they are inserted into a hole drilled in concrete or brickwork. As the bolt is tightened, it expands inside the hole creating a secure bond that won’t move or come loose over time. Expansion bolts generally have a hexagonal head with two slots for a wrench on either side for easy installation or removal if necessary. Expansion bolts also come in various sizes depending on their purpose and application. Most often, they are used for heavy loads such as roof trusses, machinery frames, and large signs.

Anchor Bolt vs Expansion Bolt – What’s the Difference

  • Expansion bolts are used to secure materials to concrete or masonry surfaces.
  • Anchor bolts are used to secure materials to wood or metal surfaces.
  • Expansion bolts are inserted into predrilled holes in the concrete or masonry surface.
  • Anchor bolts are inserted into predrilled holes in the wood or metal surface.
  • The expansion bolt expands as it is tightened, creating a tight fit against the sides of the hole.
  • The anchor bolt does not expand as it is tightened.

Conclusion:

When it comes to choosing an anchor bolt versus an expansion bolt for your project, it’s important to understand how each type works so that you can make the right decision for your needs. Anchor bolts provide strong support by anchoring pieces of wood or steel together, while expansion bolts provide even more strength by expanding inside predrilled holes in masonry walls or concrete foundations. No matter which type of bolt you choose, both are essential components of any successful construction project!
