Anchor bolts are used to attach structures such as buildings or objects to concrete, the purpose of which is to keep it in place. There are many types of these that are trademarked by manufacturing companies, but all consists of threaded ends where a nut and washer are attached. Proper installation of concrete anchor bolts is very crucial to a building. If improperly done by the contractors and structural engineers, issues with the integrity of the building and strength ratings will arise.

In order for the installation to be done properly, collaboration between contractors and engineers is important, as well as utilizing the appropriate hardware as per the engineer’s plans. Basic installation involves drilling a hole the same size as the bolt shaft then inserting it in. That’s it.

However, there are different bolts for different application; therefore, installing these varies slightly. Here are two samples:

Drop-in anchors are used in applications that are medium to heavy-duty. They come in different kinds of steels such as zinc-plated carbon. It consists of a tubular expansion shield that is paired with a solid, cone-shaped expander plug. Installation procedure is as follows:

1. Using a hammer drill with a matching drill bit the size of the outer diameter of the anchor, drill a hole in the concrete that is deeper than the anchor length.

2. Make sure the hole is clear of debris and particles.
