Chemical anchor bolts consist of two main components a threaded steel rod and a chemical resin cartridge. The rod is inserted into a pre-drilled hole in the concrete, and the resin cartridge is placed inside the hole before the rod is inserted. Once the rod is fully inserted, the cartridge is activated by mixing its contents (usually a two-part epoxy) which causes the resin to expand and harden, securely gripping the surrounding concrete.
