What is the anchor bolt?
Anchor bolts are used to connect structural and non-structural elements to concrete. The connection can be made by a variety of different components: anchor bolts (also named fasteners), steel plates, or stiffeners. Anchor bolts transfer different types of load: tension forces and shear forces.
Anchor bolts provide a strong and durable solution to connect both structural and non-structural elements to concrete material. Concrete foundation bolts are available in several different styles and size configurations to fit a variety of applications. They feature a headstamp for easy identification after the concrete is poured.
The standard anchorage depth achieves the maximum loadbearing capacities so fewer fixing points and smaller anchor plates are required. With only a few hammer blows and minimal torque slippage installation is a simple process. The drive-in pin protects the thread from damage, and ensures a faster installation and dismantling of the attachment.
Key Differences Between Anchor Bolts and Expansion Bolts
While all expansion bolts are anchor bolts, not all anchor bolts are expansion bolts. Here's a table summarizing the key differences:
| Feature | Expansion Bolts | Anchor Bolts (General) |
| Type | Specific type of anchor bolt | Broad category encompassing various designs |
| Mechanism | Relies on friction created by expansion | Can utilize friction (expansion), adhesion (chemical anchors), or a combination |
| Installation | Requires a pre-drilled hole and tightening of bolt/screw | Installation method varies depending on the specific type of anchor |
| Holding Capacity | Varies depending on type and size, generally good for moderate to high loads | Holding capacity varies widely depending on type, material, and installation |
| Applications | Suitable for concrete, brick, and some masonry applications | Suitable for various base materials including concrete, brick, masonry |
Anchor bolts might not be the most glamorous topic, but their importance in construction and engineering cannot be overstated. Often overlooked, these seemingly simple components play a crucial role in ensuring the stability, safety, and integrity of structures.
Anchor bolts may not always be in the spotlight, but they are undoubtedly essential components in the realm of construction, engineering, and infrastructure. From securing skyscrapers to anchoring machinery on factory floors, these humble fasteners play a crucial role in ensuring safety, stability, and reliability in various applications.

When choosing an anchor bolt for fastening into concrete its imperative you choose the correct one. Our concrete anchor bolts range in load ratings from 50kg to multiple tonnes, they're generally used for heavy duty fixing. Purely in terms of load rating chemical anchors are the highest load rated , then it would be through bolt anchors which can be load rated up t o as high as 3.5 tonne, then sleeve anchors which can be load rated up to 1.5 tonne, then everything else such as drop in anchor bolts, shield anchor bolts etc etc
