Chemical anchor bolts are specialized fasteners that utilize a two-part adhesive system to bond with the concrete substrate. Unlike traditional mechanical anchors that rely purely on physical expansion or friction to secure themselves within the concrete, chemical anchors use a resin or adhesive, which is mixed with a hardener, to create a strong bond. This resin is typically injected into pre-drilled holes in the concrete before the anchor bolt is inserted. As the resin cures, it forms a very strong adhesive bond with both the bolt and the concrete, leading to excellent load-bearing capabilities.

Another important aspect of bolt structure is the threading. The threading of a bolt refers to the grooves that wrap around the shank of the bolt. The threads on a bolt are what allow it to be screwed into a nut or a threaded hole in a material. The pitch, or distance between each thread, can vary depending on the application of the bolt. Coarse threads are better suited for applications where quick assembly is required, while fine threads are used for applications that require higher strength and precision
