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.

One of the most significant advantages of self-fastening bolts is their ability to provide a stronghold in environments where traditional bolts might loosen over time due to vibration or thermal expansion. Their locking mechanism ensures that once tightened, the bolt remains securely in place until intentionally removed. This feature makes them invaluable in safety-critical applications such as bridge construction and aircraft maintenance.
