M20, a common bolt size in civil engineering, refers to a metric bolt with a nominal diameter of 20 millimeters. The 'M' prefix denotes that it follows the metric system, where the diameter is measured in millimeters. The size specification does not only include the diameter but also implies the thread pitch, which for M20 bolts is typically 2.5mm.

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.
