A pin-type anchor bolt is a fastener designed to secure objects or structures to concrete or other masonry materials. It typically consists of a threaded rod with a pin or wedge mechanism at one end that expands or locks the bolt in place when installed. This design ensures strong holding power, making it ideal for heavy-duty applications such as construction, industrial machinery, or structural supports.

The installation process involves drilling a hole in the base material, inserting the bolt, and activating the pin or expansion mechanism by tightening. This action creates a secure grip, preventing the bolt from loosening under tension or vibration. Pin-type anchor bolts are often made from durable materials like stainless steel or galvanized steel, ensuring resistance to corrosion and wear.

These anchor bolts are widely used in environments that require reliable and long-lasting fastening solutions, such as bridges, columns, and large equipment bases. Their ability to handle heavy loads while resisting external forces like wind or seismic activity makes them a preferred choice for structural and industrial applications.
