Self-drilling screws, as the name implies, eliminate the need for a separate drilling step, as they have a cutting tip designed to pierce through material without requiring a pilot hole. This not only saves time but also reduces the risk of material damage that can occur with traditional drilling methods. The 1 1 4 self-drilling screws refer to a specific size, which typically signifies a 1/4-inch diameter and a 4-thread pitch. The numbers '1' and '20' often represent the diameter in imperial measurements, while '4' indicates the number of threads per inch.

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.
