Anchor bolts are essential fasteners used in construction sites, specifically for attaching objects to concrete. Anchor Bolts come in various types, each with a specific purpose. Due to the vast number of Anchor Bolts available in the market, it can be challenging for beginners to understand the proper usage of each type. Understanding the different anchor bolt types & their applications can save you time, money & effort.

Types of Anchor Bolts

Expansion Anchor Bolts Expansion bolts rely on the principle of friction to create a tight and secure connection between the bolt and concrete. These bolts expand when tightened to produce a secure anchoring effect. Expansion anchor bolts come in direct drive, wedge & sleeve types, and they are perfect for reinforcing concrete for additional stability.

Screw Anchor Bolts: Screw anchor bolts have a pre-drilled hole in the concrete, making the installation process much simpler & less time-consuming. The threads on the screw anchor bolts provide a consistent and secure hold in concrete, offering excellent gripping power for various applications. These bolt types are typically used in light-duty applications such as shelving and light fixtures.

Adhesive Anchor Bolts: Adhesive anchor bolts consist of a threaded rod and a hardening adhesive that creates a secure connection between the bolt and the concrete. These bolts are ideal for heavy-duty applications and have a strong & reliable hold also they are perfect for installing fixtures & fittings that must withstand high loads or vibrations.

Wedge Anchor Bolts: Wedge anchor bolts come in varying sizes and lengths, making them suitable for a range of applications. The threaded portion of the bolt expands when tightened, effectively locking the bolt in place. Wedge anchor bolts are ideal for installing structural steel, aluminum & other fixtures that require a high-load capacity & a secure attachment to concrete.

Sleeve Anchor Bolts: Sleeve anchor bolts are similar to expansion anchor bolts in that they use the principle of friction to create a secure connection. These bolts come with a variety of head types, making them versatile & capable of supporting various load capacities. Sleeve anchor bolts are ideal for non-heavy-duty applications such as installing handrails and guardrails.

The right anchor bolt can ensure safety and stability for your structures, giving you peace of mind knowing that your construction will withstand the test of time. While there is a wide selection of anchor bolt types, choosing the right one can be easy and stress-free with the help of this guide.
