Carbon steel expansion bolts are a type of fastener used for securing heavy objects to concrete, brick, or other hard surfaces. These bolts consist of a threaded shaft with a cone-shaped expansion nut at one end and a washer and nut at the other end. When the nut is tightened, the cone-shaped nut expands and grips the surface, providing a secure and stable anchor point. Carbon steel expansion bolts are commonly used in construction, industrial, and automotive applications due to their strength and durability. They come in various sizes and lengths to accommodate different needs.
