Wedge anchor bolt is a type of fastener that is used to attach objects to concrete or masonry surfaces. It consists of a threaded bolt with a cone-shaped end and a clip that is inserted into a pre-drilled hole in the surface. The wedge anchor bolt is inserted into the hole and then tightened, causing the clip to expand and wedge against the sides of the hole, providing a secure and stable anchor point. Wedge anchor bolts are commonly used in construction, manufacturing, and other industrial applications where a strong and reliable anchor point is needed.
