The 4 Main Styles of Construction Anchors

Construction anchors are essential in any building project using concrete materials. Anchors attach structures and building adornments to concrete. They are used for all types of projects, from dams to office buildings, making it crucial to use the appropriate variety of fasteners.

Although there are many different types of fasteners and anchor bolts, there are four main styles of construction anchors that most manufacturing companies use. Let’s discover these popular types of construction anchors and their unique qualities.

Concrete Screws

Concrete screw anchors can be temporary or permanent fixes for securing medium-high loads into brick, concrete, hollow brick, or stone. Better known as concrete anchors, they provide an immovable and quick hold. You can install these anchors in tough spaces without risking distortion or damage. These fasteners are common for installing glass curtain walls.

Wedge Anchors

Wedge anchors, also known as expansion bolts, are another popular style of construction anchors. They are popular because the application process is easy, and they are among the strongest concrete anchors available. Wedge anchors are two pre-assembled pieces threaded at the top and expanded at the bottom. This anchor is best for heavy loads and areas that frequently experience earthquakes.

Toggle Bolts

A toggle bolt, or butterfly anchor, is a fastener best used for hanging things onto materials like drywall or hollow brick. This anchor has wings that open inside the wall, holding itself against the structure to stay securely in place. The wings on the toggle bolts are bigger than the bolt, allowing it to secure the hanging item across a larger area.

Plastic Anchors

Plastic anchors mount materials like brick, concrete, or lightweight concrete. This type of anchor is inserted into a loosely drilled hole. Then, you can tighten it with a screw, not the center. The softer material expands as the screw enters the plastic anchor, allowing it to conform tightly around the screw.
