An
anchor bolt is used to attach objects or
structures to
concrete. There are many types of anchor bolts, consisting of designs that are mostly
proprietary to the manufacturing companies. All consist of a threaded end, to which a
nut and
washer can be attached for the external load. Anchor bolts are extensively used on all types of projects, from standard buildings to dams and nuclear power plants. They can also be used to firmly affix embed plates to a concrete foundation when used with a structural steel element.
