7-Shaped Easy-to-Install Anchor Bolt

The 7-shaped easy-to-install anchor bolt is a typical type of anchor bolt, named because of its "7" shape (right-angle bending structure). Its structural features are: one end of the screw is a threaded section (used to connect the upper structure), and the other end is vertically bent into a 90° hook, and the overall shape resembles the Arabic numeral "7". This design enhances the anchoring force through the mechanical bite of the bent part and the concrete. It is suitable for the foundation fixation of small and medium-sized structures. It is one of the most commonly used anchor bolt forms in the fields of construction, machinery, and electricity.
Q235B (ordinary strength, used for non-important structures, low cost).
45# steel (medium strength, used in scenes with large loads after quenching and tempering).
Q345B (high strength, used in earthquake zones or heavy equipment, tensile strength needs to be verified.
