An expansion bolt with a stud type is a type of fastener that is commonly used for heavy-duty applications where a secure fixing is required. The bolt consists of a threaded rod with a cone-shaped expansion wedge at one end, and a nut and washer at the other end. During installation, the bolt is inserted into a pre-drilled hole in the material being fixed, and the nut is tightened. As the nut is tightened, the expansion wedge is forced into the wall of the hole, causing it to expand and grip the material, providing a secure fixing. The stud type expansion bolt is designed for use in applications where a high level of axial and shear strength is required, such as fixing heavy machinery to concrete or masonry surfaces. The stud provides added stability to the bolt, helping to prevent it from rotating or loosening over time.
