Common Anchor Bolt Types: Which One Do You Need?

Anchor bolts are the key fastening components needed to build structures. Most of the engineering projects require different types of bolts. So, there are a lot of types of these anchor bolts. Some of them are used to hold the structure, and a few are needed to fix the structure. So, choosing the right anchor bolts is very crucial to prevent a structural failure.

In this guide, we are going to discuss common anchor bolt types and their applications. Understand the right bolt types for the industrial projects and plants, bridges, and structures. Let’s get started!

What is an Anchor Bolt?

The anchor bolt is used to fasten objects and structures in industrial projects. They are used to hold steel beams, columns, light poles, equipment, and machinery.

Why is it important to choose the right bolt type?

There are different types of bolts, and they are used for different purposes. The shape and orientations of the anchor bolts might be different, but their functionalities are almost the same. They are used to hold or fasten the structures.

Choosing the right bolts affects:

· Load Capacity

· Structural safety

· Costs

· Installation safety

· Durability in the harsh environments (moisture, rain and heat)

So, contractors or engineers always need to check the purpose of using the right tool. They always need to check the environmental conditions before using an anchor bolt for their projects.

Types of Anchor Bolts

Here are a few of the most used anchor bolts for engineering projects and structural uses.

L-Bolt Anchor Bolts

L-bolts form a 90-degree angle. One side of the volt is slightly shorter than the other. The shorter side is embedded into the concrete, and the larger side is left open for the fastener.

Applications

· L-bolts are used in light poles

· They are being used in structural steel columns

· L-bolts are widely used in equipment and machinery.

Advantages

· Cost effective

· Holds the structures firmly

· Used in cast-in installations

· Doesn’t get off easily once fixed

J-Bolt Anchor Bolts

J-bolt anchor bolts are the “J” shaped bolts. The curved section of the bolt holds the structure firmly.

Applications

· Used to adjust solar panels

· Used to hold steel structures

· Pole-based foundations use J-bolts

· Used in highway barriers to provide extra resistance

Advantage

· J-bolts are easy to manufacture

· They are reliable to use for medium to heavy loads

· They provide excellent holding power.

U-Bolt Anchor Bolts

U-bolts are a "U" shaped bolt threaded on both ends. They are not used for embedded systems. They are used for clamping purposes only.

Applications

· U-bolts are used for pipe supports

· They are helpful while fixing the cable arrays

· They are used to clamp small structures or pipes

Advantages

· They are easy to make and install in different projects.

· They are useful to hold round-shaped objects like round poles and steel pipes.

Straight Anchor Bolts

The straight anchor bolts are widely used in all machine types and equipment due to their maximum load-bearing capacity. They are also called headed bolts, where one side of the bolt is threaded and the other one to tighten the bolt through the fastener.

Application

· Straight anchor bolts are used in base plates

· They are used to fix steel columns

· Straight bolts are used in heavy machinery

Advantages

· They offer high load-bearing capacity.

· Offers maximum pull-out resistance.

Sleeve Anchor Bolts

Sleeve Anchor Bolts are considered one of the strongest anchor bolts used to hold large structures firmly. They are pre-assembled bolts having a sleeve on them. Once the bolt is tightened, it offers greater resistance against the wall or roof holes.

Applications

· Sleeve anchor bolts are used in Handrails and guardrails.

· They are used in light machinery.

· They are used where brackets are needed.

Advantages

· Sleeve bolts are suitable for masonry and concrete

· They are helpful for moderate to maximum load-bearing.

Wedge Anchor Bolts

Wedge anchor bolts are used for permanent installations. Once you tighten the bolt, it holds the concrete even better and doesn’t pull off easily.

Applications

· Used in heavy equipment and steel connections

· Heavy barriers use wedge anchor bolts.

· They are difficult to remove once adjusted, so they provide reliability.

Advantages

· They offer shear strength and higher tensions

· They offer greater resistance gain the vibrations, so they are suitable for industries or any other factory machine.

What are the Materials Used to Make these Anchor Bolts?

Low-quality material used to manufacture anchor bolts can compromise the safety of the structure. So. Always look for the right materials used to make those anchor bolts. Different material offers different strengths, so picking the right material is always crucial. Anchor bolts are manufactured using different materials, which include:

· Galvanized Steel

· Alloy Steel

· Carbon steel

· Stainless steel

· Alloys (Anchor bolts are made on demand for extreme environments if needed)

Custom Anchor Bolts—To Use Them in Your Engineering Projects

Most of the time, large-scale engineering projects require custom-sized anchor bolts having more strength and durability. Customized anchor bolts offer the perfect solution for your projects and do not compromise on the structural integrity of the project.
