A conical cap Expansion Bolt is a type of fastener used to secure objects to concrete or masonry surfaces. It consists of a threaded bolt with a conical-shaped expansion nut at one end.
To install a conical cap expansion bolt, a hole is drilled into the concrete or masonry surface. The bolt is then inserted into the hole, and a torque is applied to tighten the nut. As the nut is tightened, the conical shape of the expansion nut causes it to expand and grip the sides of the hole, creating a secure connection.
Conical cap expansion bolts are commonly used in construction and engineering applications where a strong and reliable fastening solution is required. They are often used to anchor heavy objects such as machinery, equipment, or structural elements to concrete or masonry surfaces.
