Indented foundation bolts, also known as anchor bolts, are designed with a unique feature - an indentation or groove on their surface. This indentation serves a dual purpose. Firstly, it increases the surface area in contact with the concrete, thereby enhancing the bond strength between the bolt and the foundation. Secondly, during the tightening process, the indentation acts as a stress concentrator, causing the concrete around it to fracture, creating a mechanical interlock. This mechanism significantly improves the load-bearing capacity and resistance to shear forces.

Furthermore, fully threaded bars offer excellent corrosion resistance, making them a durable and long-lasting solution for construction projects. Unlike plain steel bars, which can rust and corrode over time, fully threaded bars are coated with a zinc layer that provides effective protection against corrosion. This means that these bars can withstand the harsh conditions commonly found in construction sites, ensuring that the structure remains intact for many years to come.
